Send int32 Value to PC.
PostPosted: Wed May 15, 2019 5:30 am     Reply with quote

How do I send int32 Value to the PC?
for example;
Value = 1000;

fputc (Value, DEBUG_STREAM); It is sending 8 bit value. But I want to send 32 bit.

fputc, only puts a _character_. What format do you want to send
the value 'in'?. ASCII, Hex, or raw binary?.
For binary:
Code:

typedef union
   int32 whole;
   int8 bytes[4];
} combine;

void sendint32(combine value)
{
   int8 ctr;
   for (ctr=0;ctr<4;ctr++)
       fputc(value.bytes[ctr],YOUR_STREAM);
}

Called with your 'value' variable, will send the four bytes to
'YOUR_STREAM'.

For ASCII:

fprintf(YOUR_STREAM, "%LU", value);

For HEX:

fprintf(YOUR_STREAM, "%08LX", value);

Thanks Ttelmah! I logged in this morning to search for ideas on how to do a very similar thing and here it is in the first post I read!
I am interfacing to a third party telemetry system which requires some specific formatting of the data. I have the formatting done, but I was unsure of how to send the block after it is formatted. I may have this puppy working before lunch!
