Peter,

Thank you. I have an ASCII table but the character I'm receiving is not standard!

I have for example 00001111 saved in R1, how do I transform and send it via serial port in a character from the ASCII table?

I read somewhere to do:

ORL A, #030H ; Convert to ASCII number (Set upper 4 bits to 0011)

but still I receive weird stuff...Any idea?

Thanks.
Alex


The uppercase characters in the ASCII table start at decimal 65. So if you have your 4 bit value stored in R1 you could do:
Save This Code
    MOV A,R1      ; mov 4 bit value to acc
    CLR C
    ADDC A,#65    ; convert to ASCII A
    MOV SBUFF,A   ; transmitt
