Analog Multiplexer for ADC Stm32f103c8t6
Is it possible for an analog multiplexer to convert a biopolar signal to a unipolar signal? I'd like to use a homemade oscilloscope to measure positive and negative voltage.
Thanks!
Thanks!

Connect microcontroller 3.3V output to relay using ULN2803A
I have a need to connect an ARM micro-controller with 3.3V digital output pins to a few 12V solenoid water valves. I figured that I can use a ULN2803A ( http://www.kynix.com/Detail/1286058/ULN2803A.html )for this task. The internal circuit for each input/output is depicted below: http://i.stack.imgu...
