The hardware I am using is a PCB unfortunately and after futher analysis, I found that it is configured so that the Rx.d is the data pin and the Tx.d is the clock pin, is there any way to transmit 32-36 bits at one time (without skipping clock pulses)using the serial port method? Or do I have to turn the pins on and off manually? The only problem with this is that the LCD driver REQUIRES a 50% duty cycle. The LCD driver that I am using is a MM5452 (National Semiconductor). Help...Please...
