GettingOld Posted March 2, 2011 Report Share Posted March 2, 2011 Simple problem - I need to control a digital IO from Linux - preferably using an USB interface.I was going to use a MSP430 Launch pad, but the CDC serial support with Linux is not reliable. I am planning on using a TI RF2500 with the built-in application UART next but it is a little pricey ~$50.00.The goal is to control a digital relay which will in turn be used to power cycle an unreliable piece of low-voltage equipment.I need nothing more than to be able to assert an IO, wait for a bit, and then send a character back to the host application.I'd appreciate any pointers to low-cost, readily available solutions. I'm in Canada, so things I can get from Digikey would get preference. Quote Link to comment Share on other sites More sharing options...
