Hello,

I would like to interface a LCD-Graphic Display with SPI Interface to the AtomPro40..

Is the SPI Interface already implemented in the AtomPro40?

Thank you

I believe you may be able to configure the 2nd hardware serial port to be synchronous and emulate SPI. You would probably have to do your own setup of the port to do this. Not sure if you could configure it properly and use the standard HSERIAL2 support for this. My guess is maybe not.

Alternatively you could probably use the Shiftout/shiftin commands to talk to the LCD in much the same way we talk to the PS2 controllers.

Good Luck
Kurt

The hserial interrupt probably wouldn't handle the syncronous communications correctly(not saying it wouldn't though). If all you do is write it may work. SetHSerial2 to setup the hserial interrupt handler, then manually change the SCI3_2 registers to make it syncronous serial and give it a try.

If that doesn't work, just do the same thing except don't use the SetHSerial2 command. Then to send a byte you just load the transmit buffer with a byte and continue doing other things until the TEND(I think) flag is set.
