Post by thread:[PIC] MPLAB 8.6,PICKit 2,AC164110,AC162050:PK2Erro

Trying to help a buddy out here. He has the latest version of MPLAB, an old PICKit2, and he wants to develop some code in the 12F675. I told him he really needs to be able to debug, and we looked up the docs for debugging that chip with the PICKit2. As far as we can tell, you can do that with a special header: The AC162050 which contains this special little version of the chip: PIC12F675-ICD. To connect the AC162050 to the PICKit2, you must have an ICSP to RJ-11 adapter, the AC164110. So we ordered both those parts from Digikey and they arrived. We hook up the PICKit2, update the firmware, connect the RJ11 adapter, and the AC162050. MPLAB sees the device, sees the chip (once we got the RJ11 adapter on right way round) and we can program code into it... But we can't debug. It says: PK2Error0028: Unable to enter debug mode NOTE: This device requires an ICD Header for debug. See "Header Specification" DS51292. PICkit 2 Ready http://ww1.microchip.com/downloads/en/DeviceDoc/51292S.pdf is exactly where we found the info on which ICD header to purchase. And sure enough, it says for the PIC12F675, you need an AC162050, which we have right here in front of us, plugged into the PICKit2... ??? The jumper is in the right place (pins 1 and 2 are shorted) and we can program the chip... and it verifies... and won't debug... help? -- James Newton 1-970-462-7764

Some of the first ICD header models have some special constraints (I don't remember if some applies to 12F675): 1) Some devices won't work when using both internal oscillator and MCLR disabled at same time. 2) Some devices won't work if a certain pin is pulled-up during reset (I think it is RB4). This pin must be pulled low during reset. I think this doesn't applies to 12F675.

This is a warning, when some of the configuration bits were not set up right, which will prevent the chip from entering the debugging mode. E.g. Debug bit wasn't turned on, WDT wasn't turned off, etc. Funny N.

I know you already got the hardware and want to make it work, but as a alternative to just getting the code developed how about sticking to the simulator? I don't think I've ever used a ICE or other hardware debugger on such a small chip. The simulator is definitely the nicest debugging environment if you can manage to simulate the inputs properly. That sometimes means writing host code to generate a .STI file, but that's usually easy to do. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.

When debugging a chip that needs a header, MPLAB IDE expects the ICD version, but there is no special ICD version on the list to select, just the normal one.

I'm not finding a "debug bit" in the config. The device selected is "PIC12F675" and that is the only option I see for that device in the list. There is no debug version, as far as I can find, e.g. no PIC12F675-ICD listed. The chip we are connected to IS a PIC12F675-ICD. The project build configuration is debug, not release Under build options, on the compiler tab, Debug optimization is on. Config is currently FOSC Oscillator Selection bits RC oscillator: I/O function on GP4/OSC2/CLKOUT pin, RC on GP5/OSC1/CLKIN WDTE Watchdog Timer Enable bit WDT disabled PWRTE Power-Up Timer Enable bit PWRT disabled MCLRE GP3/MCLR pin function select GP3/MCLR pin function is digital I/O, MCLR internally tied to VDD BOREN Brown-out Detect Enable bit BOD enabled CP Code Protection bit Program Memory code protection is disabled CPD Data Code Protection bit Data memory code protection is disabled Oh... hang on, there it was... Should have been "INTOSC" not "RC oscillator" I was confusing that setting for the /internal/ RC oscillator... Ok, all better now... Thanks for the hint. PICList rocks as always! -- James Newton 1-970-462-7764 {Original Message removed}
