Flowcode Support Board

Hi,

Its the first time i have tried to use this chip. (24FJ128GB202), usually i have used the 24HJ128GP502.

I created an empty project and attempted to build to Hex file.

I get a compile error as below

Obviously its connected to the 'AD1PCFG'

//------------------------------------------
int main()
{
AD1PCFG = 0xffff;

mainendloop: goto mainendloop;
return 0;
}

Thanks in advance

Hi

Did you check the datasheet for this device, it is possible that the register name has changed / or it does not have this register,
you need to check this ! These are the things you need to do if the register exist exactly the same as in the old chip then it is possible that the definition file in FC has an error ,Then you report a bug .

Hi,

i appreciate and respect your comments but this is a licence issue.

Hi Andy,

As p.erasmus says, looks like we have a register name issue
please try the attached FCD, to go into directory
C:\ProgramData\MatrixTSL\FlowcodeV9\FCD\PIC16

nb. please first rename the 24FJ128GB202.txt file to 24FJ128GB202.fcdx

Hi,

I tried the new file but the result is the same.

Hi

the register is ADxPCFG

Andy

The line in question is part of the initialisation and puts the port pins into digital mode as a default.

Looking at the header file in the toolchain, it looks like registers ANSA and ANSB control the a/d nature of the pins, and so the line in the FCDX file near the bottom should be changed from this:
to this:
There may be some other edits required to ensure ADC inputs are configured correctly when used.

Doh! Just beat me to it
Having read through two datasheets ...
And it looks like ANSA etc needs to be set to 0 for digital mode.
So the edit needs to be
ANSA = 0; ... etc

Thanks for the correction, Leigh. In my haste to beat you, I misread the datasheet!
