Print Hex format issue
PostPosted: Sat Jan 01, 2022 4:47 am     Reply with quote
Hi All
I have a basic question.
I am using PIC16f877A along with CCS compiler.
I am stuck in a little thing.
I am serially out the following code
Code:

unsigned char command_send[] = "^P005ID";
unsigned int crc_low = 25;    // Hex is 19
unsigned int crc_high = 205;  // Hex is CD


Code:

printf("%S",command_send);
   printf("%X",crc_low);
   printf("%X",crc_high);
   printf("\r");


instead of getting (actual result) --> ^ P 0 0 5 I D 19 CD 0D

I am getting this --> ^ P 0 0 5 I D 31 39 43 44 0D

means 19 is break into 1 and 9, also same for CD.
How to tackle this?

Thanks

That is what would be expected. %x prints the characters in _ASCII_ hex.
If you just want the character 19, then use %c.
