![]() Also don't try to learn/solve too many problems at the same time. I think its best to start by utilizing your software experience as much as possible and having just enough hardware to get by. I air-quoted medical devices to make it abundantly clear that whatever we made was never ever ever used to diagnose any patients. ![]() We went through many chips due to mis-configured serial port connectors but it was so worth it. Just the mere act of programming one was amazing, you'd have to use SDCC (small device c compiler) to convert your C code to assembly that 89C92 understood, in process I built my own chip burner and use some combination of PonyProg to burn it. My then girlfriend (now wife :))'s project was EKG wave generator, essentially a device that simulated signals out of a human body that one can use to test EKG devices. ![]() First successful project was a commoditized Vibration Perception Threshold meter, ones made by bigger companies used piezoelectric crystals costing upwards of 10s of thousands of rupees - I built one using relays and 89C52 to create a square wave of varying frequency to change vibration frequency. It was such a fun experience building "medical devices" with these chips. I have fond memories working on Atmel chips, started with 89C52 and graduated to ATmega8 later on.
