icd-u40

ICD-U40 is a perfect solution for debugging and programming PIC. It's fully independant from MPLAB, well integrated in PCW and is quite cheap. It has very advantages vs ICD2, at least it's faster. Here is the circuit and PCB for those who want to make it themself.

The following times represent the time it takes to execute a single step command on a 1 Ghz PC:
MPLAB USB ICD-2 1.36 seconds
PCW serial ICD-S40 (40Mhz) 0.16 seconds
PCW USB ICD-U40 0.24 seconds

Don't ask me for the firmware, is very easy to obtain, this is in your PC :D

Regards......

Being MPLAB independent is not necessarily a good thing. It supports its own IDE and appears to be reliant on CCS C which has a rather crippled demo version (2K program, limited PIC support PIC16F877, PIC16C544 and 16 bit PIC18F458)

Note: the 1.36Sec MPLAB USB ICD2 step rate seems more like RS232. Are you using a non 18F4550 version, that thing steps very fast.

PS on a side note; by the sheer number of programmer and or debugger threads here I often wonder if anyone actually builds projects or just spend all their time building programmers...

And an ugly interface IMHO.

Hi nooknikz

Work perfect and very fast, I debug the pic18f4550 Step by Step in a powerful C debugger!!
 
icd-u40 firmware

Hi Folks,

Nice job !
Can I use a max232 instead FT232 ?
If possible , DTR signal must be inverted ?

Thanks

Hi wjr1955

Yes you can use max232 and this programmer is called ICD-S40, keep the dtr signal non inverted and the ICD-S40 is powered from the target board

You need to swap anode and cathode of LED LD4

icd-u40

is it possible to use 18f452 instead of 18f252 ?
if possible which firmware should be use?
 
icd-s40 clone

hi everyone,

i was in hurry when i post the board, and i miss something to mention:
- on this board you have just to make a wire connection between R40 and D3 -anod, on the bottom board.
This is because i forget to cut the Q1 colector and VPP led from the Vdd, with the D3 diode. And i also connect the Vpp led to the Vdd, instead the ground.
So i introduce the D3 diode after the pcb was finalized, and i put a via close to the R40, for this wire connection.

Added after 1 minutes:

18f452 is a 40 pin device, not a 20 pin device as 18f252. But if you arrange the PCB and the firmware should work without any problems with the correct fuse settings. Like disabling the extra peripherals of 18f452 with the fuses.

Hi, folks.
Do you ave schematic for new revisions of ICD-U40, wich support dspic, or J series?

Thanks.

Hi. Any body have eeprom content for FT232R?

Thanks.

Here is the CCS U-40 or/and S-40 (either of them will do) debugger firmware. If you need...

Hi folks

are you have eeprom for FT232RL ? And how to program to FT232RL ?

Thank you very much

NICE WORK FOLKS.

CAN WE USE 18F2550 INSTEAD OF 18F452 AND REMOVE FT232 ?

Hi. FT232R can be programmed with MProg but eeprom content is missing:

hi nooknikz
you have to download the datasheet for the rl chip, from the www.ftdichip.com and also the program utility for eeprom programmer, called MProg. (it was version 2.9c when i played with this). All avaible on the web page. Its quite easy to play with this utility.
this is the newest Ft232 chip, with eeprom inside the device, with no external crystal.
