Yes thanks for the quick test to confirm the CCS bug is now fixed. Looks like I should throw some money in the direction of CCS.

CCS version 5.025

I have been working on an application which uses the USART on the 12F1840 at 115,200 baud.

I used these values to setup the USART:

#use delay(INTERNAL=32MHz)

// ...

Thanks for the confirmation guys, thats save me having to scratch me head to think how to test this. Just goes to show how carefully you have to read datasheets before you can infer a meaning.

I am using a timer interrupt to keep a microsecond time value updated. The code below seems to work fine.

However as I turn the timers IE off whilst I compute the time value to be sure I don't get ...

Well its no different if I replace with this :

void SetPathOutputs(path *p)
{
int i ;

// Set the static bits
for(i = 0 ; i < OUTPUTS ; i++) {
if(i >= ...

Just add some further evidence. I was about the post the following code which seems to fail for the same reason. i.e. If a bit array is used in a struct there can be problems. In my case simply pu ...

It might be worth trying with different value names as well incase of conflicts. It could be OFF is a popular value defined somewhere else. eg.

enum colors {__OFF, __RED, __GREEN} color; ...

Well it could be I mis-understood something. I just went back to trying 'const' again and I don't see any code before the program data for the structure access.

That is :
#define OUTPUTS 36

/ ...

I don't see how putting the 'rom' data declartion inside a function realy helps any. As even if the function is #org'ed to a fixed memory address the compiler puts the function at the #org address ok ...

Yes, I can se how these suggestions might work but all gets a bit messey.

Using a function wrapper around the data with a label means the scope of the label is only within the function. Thus label ...

I was looking to place read only data structs into some program memory at a a fixed address.

If I use const in combination with #org I can place my data where I like. However since const puts some ...

Dear Ttelmah

See list output below :
FYI, I also found to test for Non Zero in RAM bit arrays I need to use "if((int8)xyz.................... void test()
.................... { ...

Dear Ttelmah

Thanks for testing this, atleast I know know its a compiler bug. However even paying for another maintenance update is not going to fully solve it for me. Makes sense to hold onto my ...

When you get it working for ns post the code. It will be interesting see how to accuratly handle the interrupt latency.

Dear Ttelmah

Thanks for the explicit code but, Nope ! Still don't work that way either, unless I am being dense. When you say it works, have you tested it ? If so which version gave the correct r ...
