#160220 - A question about numbering ranges |
I have a ezLCD-004 display that I need to write to.
It's X,Y limits are 320 x 234 pixels Communicating with the display via RS232 and writing code in assembly. Processor for now is a AT89LP4052 - will have to upgrade eventually to fit all of the code. If I want to write to the very last X pixel I will need to send a decimal value of 320. MOV SBUF,#320 appears to be beyond the HEX value range of 0 to 255 (#00H to #0FFH) The SBUF would need to send more then a 8 bit value to reach this last pixel. Does it do this if I load a decimal value of 320 or is there some special trick to send more then 8 bits per SBUF load? |
