String to Hex number
PostPosted: Wed Jun 20, 2007 10:37 am     Reply with quote

Using Compiler PCM 3.242, PIC 16F877.

I have a string of variable length that is received from another device via serial port in the following format (without quotes)

"data7E3B99D7"

After the word data, I need to extract each 2 characters into an int8 array as follows:
mydata[0] = 0x7E
mydata[1] = 0x3B
mydata[2] = 0x99
mydata[3] = 0xD7

Can someone give me a piece of code that can convert the string data into hex numbers and put them in this array?

Thanks.
