ARM7 (LCP21xx, 23xx, 24xx) & cortexM (LPC17xx,13xx,11xx) register settings wizard

[alexan_e]

Hi
I have used AVR's for a few years and I'm trying to learn how to use ARM7 and specifically the NXP/Philips LPC2103 and maybe LPC2131.
I was wondering if anyone knows of an application that includes a wizard (like the codevisionAVR) where you can select the function of the pins , inputs/outputs , enable and setup timers, ADC etc. and automatically create an initialization file with the registers setup values for the selected functions.
I' don't mean the start up file which is made automatically with applications like Keil uvision because this file has a different purpose.
I wasn't able to find such an application and it would make life much easier.

Alex

Re: ARM7 (LCP21XX) register settings wizard?

Only pdf can help. ya i also felt that the same way after running with ARM from 10years. wish i had a tool. there is no help other than pdf register information

Re: ARM7 (LCP21XX) register settings wizard?

I wasn't able to find any software that can help with the configuration of resisters so i have started my own freeware application.
This is the first version of the software, it can help to set up the mcu pin registers that control the function of the pin and I/O direction.
I will add more features and I will post them here as I do,
my intension is to add timers, interrupt, ADC, SPI.

The current version Supports the following mcu but i will also add some more later.
LPC2101-02-03
LPC2131-32-34-36-38

I have also created a web page for the software, you can find my home page through my profile, but i will also post the latest version here too.

Alex

P.S. this is a windows application but all the library needed are included in the executable so it may work using WINE in linux but i haven't tried.

Re: ARM7 (LCP21XX) register settings wizard? (ARMwizard v1.1)

I have updated my application to v1.1,
in this version i have added a screen where all the available interrupt
sources are listed , from there you can select the needed interrupts and place them
in the selected interrupt vectors.

The code generated includes the main function, the interrupt functions and
the initialization of them and of course the settings for registers that control
the function of the pins and I/O direction like the previous version.

LINUX USERS
I have tested the application in PC-Linux using WINE, unfortunately there is a
problem in the I/O page and the mouse position is not detected properly.
The only workaround for now if to use the arrow keys to navigate and
space to select/change, also the + and - expand/collapse the tree nodes.

The supported mcu list is the same as the previous version
LPC2101-02-03
LPC2131-32-34-36-38

You can download from **broken link removed**

This is a sample of the interrupt screen

Re: ARM7 (LCP21XX) register settings wizard?

I have just uploaded the new version (v1.1.1) to my page ,
it is a minor update in the functionality of the application but i have also added the following devices
LPC2104-05-06
LPC2141-42-44-46-48

This included mcu should cover now the most popular models in the 21xx series i think.

Re: ARM7 (LCP21XX) register settings wizard?

I have released version 1.2.1 of my freeware application

The application has settings for the A/D converter,can initialize the direction and
functionality of pin registers and also setup the interrupt sources and adds automatically
the interrupt functions and initialization code.
You can view a sample of the generated code in previous posts

Supports
LPC2101-02-03
LPC2104-05-06
LPC2131-32-34-36-38
LPC2141-42-44-46-48

Visit my website through my profile (i have also added RSS to my page),
or download directly using this **broken link removed**

What is new in ARMwizard v1.2.1
-------------------------------------------------

• the application is now fully compatible with Linux using WINE
• a fast selector menu has been added which serves a dual purpose
  - shows which alternative pin functions are enabled
  - goes directly to the pin with the selected function when clicked
• added pin diagram pictures for all included ARM mcu [ajishgopalr edaboard.com]
• some small fixes of function descriptions for the mcu pins
• FIO checkbox, when checked the generated code uses Fast GPIO registers and adds the initialization

Re: ARM7 (LCP21XX) register settings wizard?

I have uploded ARMwizard v1.3 to my website.

what is new in v1.3

• Added external interrupt settings in the interrupt tab, these are automatically enabled when an external interrupt is added to a vector
• Added timers tab for up to four 16/32bit timer settings, all the settings are available using check boxes, dropdown and edit boxes.
• All the mcu pin diagrams pictures have been resized to have a height of 650 pixels because in the previous version some of them had a height of more than 768 pixels [ajishgopalr edaboard.com]
• The first mcu profile is now automatically selected in the combobox (not loaded)
• The frequency is automatically converted to MHz/KHz/Hz and period in ns/us/ms/s for easier read

The settings included in this version are

• GPIO, select inputs/output direction or any alternative pin function using a convenient graphic interface and also a quick selector which has all the functions in groups.
• Interrupts, select from a list any of the available interrupts sources and add them to the selected vector, the functions will be created automatically.
• External Interrupts, set the external interrupt options using combo boxes.
• A/D converter, set any aspect of the ADC (mode, channels, interrupts etc.) with explanation for every setting and see the calculated clock and sample rate without having to calculate anything.
• Timers, set any aspect of 16/32 bit timers (mode, MAT, CAP, interrupts etc.) with explanation for every setting and automatic clock calculation.

These are images from the added settings

And this is a sample code for the added timers and external interrupt code

Re: ARM7 (LCP21XX) register settings wizard?

ARMwizard updated to version 1.4

What is new

• Added the PWM settings tab to set all the registers of pulse width modulation
• The last loaded configuration file (.sav) is stored and used as default path/name when you restart the application and press load configuration. [Simon B.]
• The PR register of Timers, MR0 register of PWM and CLKDIV of ADC have a right click function to set value by target frequency or period. [Simon B.]
• The CCLK clock frequency is always common and can't be set individually for each peripheral.
• Added individual PCLK setting for each timer for chips that support it (23xx, 24xx).
• ADGINTEN (in ADC) is now enabled by default since the reset value of the register is 1.
• The load button is now enabled when the application starts.

this is a sample of the generated PWM initialization code

Re: ARM7 (LCP21XX) register settings wizard?

ARMwizard updated to version 2.0
This is the first version that supports the LPC17xx Cortex M3 chips (LPC1763/64/65/66/67/68/69), more 17xx models will be added in newer versions.

What is new

• Added support for LPC17xx chips, includes LPC1763/64/65/66/67/68/69 mcu profiles
• Added pin setting for open drain and repeater mode for LPC17xx
• Added GPIO interrupt trigger edge selector to enable interrupts for selected GPIO pins
• CLKDIV register of A/D can also be set by target sample rate ( in addition to A/D frequency)
• When Timer2 & Timer3 is used the PCONP enable bit is set to enable the timer operation

Re: ARM7 (LCP21XX) register settings wizard?

ARMwizard updated to version 2.0.1

What is new
• Added support for LPC1751/52/54/56/58/59

I had to release v2.0.1 one day after v2.0 because I have added the LPC175x chips and I had to make a few changes in the application to work correctly with them (no capture registers are available in timer 2 and 3 in these chips).
A download of only the profiles wasn't an option, sorry for the inconvenience.

Re: ARM7 (LCP21XX) register settings wizard?

good work.
On which platform did you create this software?

 

[alexan_e]

Re: ARM7 (LCP21XX) register settings wizard?

ARMwizard updated to version 2.0.3b

What is new

v2.0.3b
• Fixed: The pclock is common only in LPC177x/8x. For LPC175x/6x there are individual divider settings

v2.0.3
• Fixed: the Pclock couldn't be set over 100MHz in LPC17xx ADC, now the limit is 200MHz [Johann Zimmermann]
• Fixed: in LPC17xx the Pclock divider is now common and can be set to 1/1 - 1/31

V2.0.2
• Removed: __irq prefix from LPC17xx functions [Phil Young LPC2000 forum]
• Added: The missing exception interrupts for LPC17xx
• Added: Bit masking for reserved bits of PCONP, SCS, INTWAKE registers
• Added: Support for LPC177x/8x having the IOCON register
• Added: In quick selector if a pin of a function group is set then the group is also shown with a checkbox
• Fixed: when the external match checkbox were enabled in timers the match control register stop and reset bits were disabled.
• Fixed: The motor PWM input pins were shown in the SD/MMC section of quick selector
• Fixed: a few pins functions in LPC2470/78 were not commented

Re: ARM7 (LCP21XX) register settings wizard?

Could the registers NOT presently supported be listed somewhere, or placed on a Misc tab?

For example, I couldn't find the RTC configuration registers anywhere.

Thanks for a great product!

PS: V2.0.3b runs great under 32-bit Ubuntu 11.10 + Wine 1.2.3.

Re: ARM7 (LCP21XX) register settings wizard?

I'm adding the peripheral tabs with all the related registers settings as I add new functionality to the application.
Having tabs with registers of peripherals that are not implemented would mean that there would be no settings so I don't see the point of setting a bunch of registers to the default value when you have to lookup at the user manual anyway in order to use them.
In addition I have to read a bunch of manuals each time I add a new peripheral in order to check which registers are available in each mcu and add them so even adding just the names would require a lot of time.
In addition I also have to check the keil header which often uses different names in the header (compared to the NXP user manual) in which case I use a set of defines in order for the original names to be working properly.

Thanks for the feedback on Ubuntu 11.10 + Wine 1.2.3.

I wasn't thinking of full support, but just a list of registers for the selected processor that don't have full support, that I can select to put a comment in the generated code to remind me to look it up and set it.

Perhaps an "Unsupported" tab with a sorted list of "extra" or "other" registers, a 1-line description, and a checkbox to add a comment for that register to the output.

And, maybe, an optional box to enter a hex or binary value, to be used after I do look it up. That way everything can reside within your app, even if is not fully supported..

Re: ARM7 (LCP21xx, 23xx, 24xx) & cortex M3 (LPC17xx) register settings wizard

ARMwizard updated to version 2.1 , added SPI/SSP settings

What is new:

• Fixed: There were cases where the CCR1.0 checkboxes were not shown for PWM
• Fixed: The PCLK divider range was 1/1 - 1/8 instead of 1/1 - 1/31 for LPC177x/8x
• Fixed: The PWM power control bits (PCONP) were not set to turn on the peripheral in LPC177x/8x
• Fixed: The ADC1 power control bits (PCONP) were not set to turn on the peripheral in LPC2134/36/38
• Fixed: There was an erron in the name of the included header for LPC2141
• Fixed: In LPC175x/6x the right click on the pull up/down triangle didn't change the mode correctly (from up<->down)
• Added: All edit box values can now be increased/decreased using the up/down arrow keys (like spin edits)
• Added: For desktops with vertical resolution lower than 660 the ARMwizard form is reduced to 550px and a scrollbar is shown
• Added: SPI/SSP settings for all the included mcu models
• Added: Set the power control bits (PCONP) to enable every used peripheral even if the default setting after reset is on
