PIC32 micro controller tutorial

pic32 starter kit

Hi.

I would like to know if someone have already designed a board to use the hirose connector of the PIC32Starter Kit in order to use the peripheral devices.

If you have devolped one, please post it here.

Thanks

I never use PIC32 start kit from Microchip because I build the one for myself. I share it for everybody who want to develop it.

how to program pic32

Hi KST, thanks for your help.

The schematic you have posted is for buildin a development board, right?
And how do you program the pic32??

pic32 development board

Microchip do have a board the the starter kit plugs into and lets you access the ports.

On the schematic KST provided you see the connector named "ICSP" (Header6).
Well you can use the ICD2 or REAL ICE from Microchip to programm or debug.

You should use MPLAB v8.15 or later, compiler is the C32 from Microchip, programmer is the ICD2. Good luck for you !

PIC32 Starter Kit

KST, thật vui khi gặp thành viên là người Việt Nam ở diễn ðàn này ---> I am very glad to see Vietnamese people here ^^

Good job KST

well i have placed PIC32MX360F512L device on a simple board...and added some capacitors to it...and tried to connect to PICKit2...and it says to me VPP voltage level error... however i did connect everything right... but only thing which is weird for me on this PDF schematic is u are using inductor between avcc and agnd???

or what?

You should try to test kind of your PIC, may be PICKIT2 don;t support for this PIC.
Good luck for U !

MPLAB IDE doesn't support prgm/debugging PIC32 using PicKit2 but, pickit 2 stand alone programmer will support PIC32 programming.

Re: pic32 schematic

Hi,

I've saw your dev board to pic32. Could you share project files like pcb design ?

It's sound good. So, you mean third party PicKit2 software can program PIC32? I have bought PIC32 starter kit and only have PicKit2 programmer.

For thread starter, this is one of PIC32 Starter Kit.

I was under the impression that the pic32 starter has a built in programmer and debugger and is accessed via the supplied usb cable
