Hi, what would be the easiest way to generate a triangle wave of for example .5-4.5V in the kHz range? I've heard of waveform generators such as the XR2206 but also that they were obsolete and that using a microcontroller would be a more 'modern' method and to be honest it does look like theres a lot of resistors and capacitors you have to hook up to the XR2206 to get it to function the way you want whereas maybe with a microcontroller much of what you would have to do could be done in code. Which one would be easiest or is there an even easier way?
