Hi!
I try to send the data between the Aduc and the display by 5V TTL serial!
As i said in the previous post the ADuC interface it's composed of 5V, GND , TXD and RXD.
The display provides as mentioned above the TTL Serial interface ( 1 start bit, 8 data bit , 1 stop bit ).
What i want to do it's show a single string send by the ADuC.
The UART interface it's intialized with SCON = 0x50 and the SBUF register contain always a single char.
The baud rate between the two device it's 9600 ( the core clock it's 12,58MHz with TH1 set to 253 ).
For this moment i can't see anything.....Any advice?
