Your are correct (again) Ttelmah. My default stack size was only 128 bytes.

I got the 256 byte size idea from the CCS docs: "STACK configures the range (start and end locations) used for the ...

Hi jeremiah. I was just doing a sprintf of a float (32 bits) to a string along with some very simple URT ISR receiver code. Increasing the stack from 256 to 512 bytes fixed the problem.

Ttelmah you were 100% correct that it was a stack overflow issue. The problem went away when I increased the stack size. It’s interesting that one sprintf and a simple UART receive ISR function co ...

Hey Ttelmah thanks to you and everyone for the feedback. I confirmed that the ISR fires after every received byte (this is the default). My ISR code is very quick. All it does is update a rolling b ...

Thanks PCM programmer for the link. It looks like I'm handing the ISR correctly. Smile

Thanks the quick reply asmboy. I completely understand what you are saying and trust me I've never pulled more than one char at a time from int_rda in my PIC18F products but the way I interpret the d ...

Hi guys.

Is this an effective way to handle the 4 deep FIFO receive data buffer ISR on a PIC24F? I know about URXISL <1:0>but even set to 00 more than one byte can be in the receive buffer (I ...

Yeah I got it. Well I certainly appreciate your wisdom. Many thanks.

Oh snap. Yes I am using a 24F chip and no I was not aware that for PCD IEEE is the standard format for floats. In my defense I saw the PCD conversion functions in ieeefloat.c and assumed I needed to ...

I really think I have the code correct now but I am getting 0's! grrrr!

OUTPUT RESULTS: source.fver:98.59 ...

Ah the power of the union statement.

You're awesome. Thanks Ttelmah!

Thanks for the reply newguy. I'm glad it's a bug and I'm not totally crazy but I still get the following result:

myFloat: 0.00

With my code:

int32 ieeeValue;
float32 myFloat;

ieeeValu ...

Hi guys. I'm embarrassed to ask this but I need a sanity check regarding ieeefloat.c. I must be looking at this wrong. I’m using version 5.027 of the PCD compiler. Can you tell me why f_PICtoIEE ...
