A/D compiler issues

[BobEdge]

Hi,

Ever since I have been using PBP I have had the same problem. If using MPASMWIN the A/D converter module does not work, and just reads zero. In the past this was not a problem as I had the option to use the other compiler, the one where you don't get progress bars during compile.

Trouble is I now only have 64 bit OS and the old compiler will not work. I have upgraded PBP, and am currently using PBPX3.0.6.4, with micro code studio 5.0.0.3.

I have a project that uses the A/D converter ,and really need to get it working. Can anyone please help?

I originaly posted this in the PBP 3 section, but noone is viewing that, so I have posted here.

Kind regards
Bob.

Hi, Bob

could you provide some enlightments, please ... one full "faulty" program would be the best.

Hi Alain,
Here is the code. PIC16F870 by the way.

define OSC 20
define adc_bits 10
define adc_sampleus 50
trisa = 255
adcon0 = 129 'Internal clock, channel 0, switched on
adcon1 = 142 'Right justified (10 bit), channel 0 analog

adcin 0, temp
let temp1 = temp * 3
let temp2 = (temp * 5) / 100
let temp = temp1 + temp2
serout serial1, 2, ["A",#temp,"AA"]

This exact same program has been working fine for around 4 years. I have always had the same issue. If using the compiler with the popup window with progress bars the A/D does not work (same with many different chips, and projects) if using the other compiler everything was fine.

I have been using PBP for many years with micro code studio, and have always had the same issue. I no longer have a 32 bit operating system, so I can't even install my older version of PBP, and use the doss compiler. With PBP 3 I only have the option to use MPASMX or not, and both give the same result, the same result that I'v had since PBP 2.4ish.

Hi,

Issue solved. Many thanks to Henrik. The old assembler (PM) was not case sensitive, MPASM is.
Changed define adc_bits 10, and all of the other config parts to capital letters, and all is fine.

Sorry about the dual post, but I was getting no replies in the PBP 3 section. If a mod could delete one of them that would tidy things up.

Kind regards
Bob.
