Hi, Is anybody aware of a 'ready to go' I/O expander that can be attatched to a standard async memory bus?? I know phillips/maxim etc do I2C and SPI I/O expanders but I can`t recall seeing a device that would attatch to standard address/data bus. I realise something could be knocked up with a couple of latches/some gates or some sort of programmable logic device but I was wondering if anything was available off the shelf first. cheers, best regards, Andrew Seddon -- http://www.piclist.com#nomail Going offline?
