Help - programming problem!

Help urgently please!

I'm running behind on a project and am having some problems with programming.

I thought I'd try out the PIC16f722 as I need capacitive buttons , have never used the device before. However I cant get my programmer to detect it. I'm using PICKit 2 program with a programmer by ETT called ET-PGMPIC USB I assume it's just a copy of the microchip one - as it uses microchips software.

I've tried my old chips on it - ie 16F88 and it detects those fine, however it will not detect the PIC16F722 - it just comes up with "No Device Found" if I try and read it, it says "Unsupported Part (ID = 1880)"

initially I tied it in the ZIF socket but it didnt work, so then I tried it ICSP mode, still nothing. The Vdd goes to around 6V for 100ms when I check communication - so it's getting enough voltage.

Anyone programmed this series of chips? Is there anything Im missing? I updated the operating system on PICKit successfully thinking it may have been outdated but still no joy.

Any help as always would be greatly appreciated.

Thanks

Maybe that's the clue... the software programmer does not or can not identify the part. Unless there is a more upto date version, you might be out of luck. Alternatively check Microchips website to see if there is a more uptodate firmware available...

Thanks Malcom,

It says that unsupported part error ID=1880 if there is no micro connected - so ya not sure really what it means. Downloading the latest update from Microchip was the first thing I did.

Am just wondering whats specific about these chips thats giving me a problem - is is just because they are new?

I see people on here have programmed them with no signs of issue - what are they doing that I'm not?

Ok, I splashed out and bought a PICKit 3, the latest upgrade to PBP, I'm now using MPASM as it recommends using it, I'm only an occasional user of PBP

However I get a tonne of errors Why doesnt' it just work? If I spend money I expect it to work without too much drama.

Errors are things such as: symbol not previously defined (ADRESH)
Illegal opcode

But there are tonnes...

Here's my code: - BTW - how do I put this in that neat little code window on here?

@ DEVICE PIC16F722, _DEBUG_OFF
@ DEVICE PIC16F722, _BOR_OFF
@ DEVICE PIC16F722, _MCLRE_OFF
@ DEVICE PIC16F722, _PWRT_EN
@ DEVICE PIC16F722, _WDT_ON
@ DEVICE PIC16F722, _XT_OSC

DEFINE OSC 4
DEFINE ADC_BITS 10 ' Set number of bits in result
DEFINE ADC_CLOCK 1 ' Set clock source Fosc/8 "2uS"
DEFINE ADC_SAMPLEUS 50 ' Set sampling time in uS

ADCON0 = %110011
ADCON1 = %1000000

TRISA= %00000000 'Set 'em all to outputs
ANSELA= %00000000 'Set 'em all to digital
TRISB= %11111111 'all input
ANSELB= %00000111 'LAST THREE ANALOGUE
TRISC= %00000000 'Set portC all outputs

CPSCON0 = %00001101 'Cap sense off

'-----Allocate Variables
ButtonSense VAR byte

Start:

ADCIN 13,ButtonSense
PORTA = ButtonSense
goto start
end

Those are for PM not MPASM.
I would try generating your HEX like you always have. Then load the HEX.

If you are using MPSAM then I beleive you need to edit the INC file in the PBP2.60 folder and comment out the config lines - this has been documented so a search of the forum should throw up plenty of examples.

As for placing code in a box, if you use " [ code ]" & "[/code]" (without the quotes ) it does the job

Code:
