Hello Martix team,

i belive I found a Compiler Problem in my professional PIC Version 6.1.1.0 with the I2C CAL component.

The Compiler alway Returns the following error message:

Licensed to FlowCode User under Single user Pro License for 1 node(s)
Limitations: PIC18 max code size:Unlimited, max RAM banks:Unlimited

Attached the FC6 file too. Any ideas to solve this Problem

Hi Dirk,
If you change properties of I2C component from Channel2 to Channel1 then you should be able to compile ok?
Looks like there is a bug with channel 2 as its trying use a register which does not exist.

I'm not that familiar with I2C, so not able to sort it without affecting something else.

Are you ok using channel 1?

Martin

Hi Martin,

many thanks for the fast reply. Yes compiling with channel 1 will solve the Problem.

In my Hardware I can not change to Ch1 because of a existing PCB were the ports c3 and c4 are already used.

Do you see any Change to fix this issue??

Hi Dirk,
I have modified attached file so channel2 now compiles ok.

can you make a backup of PIC_CAL_I2C.c in C:\Program Files (x86)\Flowcode 6\CAL\PIC\
and replace with attached file.

Since I don't really know what i'm doing with I2C I can't guarantee it will work of course.
If not working then you can always try software mode.

If I have not modified PIC_CAL_I2C.c correctly then I'm sure someone who knows what they are doing like Benj will sort modify file correctly.

Martin

Thanks Martin,

Just done a little tweak, attached, this will now go into the repo.

Thanks,
Leigh

Thanks Leigh,
I was so Close.
I'm assuming the file I posted would have worked for Dirk,
But would cause an issue with a different target device?
Martin

I'm sure it would have been fine. If channel 1 does not have control register 3, then channel 2 wouldn't have either

Thanks guys!!
