Hi guys,
I'm using an NEC v25 upd70320 MCU (http://www.digisolutions.de/downloads/NECV25Datasheet.pdf) and an itl710 touchscreen (http://www.comfiletech.com/index.asp?PageAction=VIEWPROD&ProdID=129).
Right now I have the two connected via serial port and I poll to see if there is anything new on the serial port. What I would like is everytime I press a button on the touchscreen, it should generate an interrupt on the MCU. I'm not really sure how to set this up, I know a bit about interrupt programming but not how to set up the hardware. Any help would be great.
Thanks.
