Hello!
I'm working on a project where I need to toggle a VESC-type ESC between off and "on" (no variable throttle) with a momentary button. One press on. Another press off.
I've designed the following circuit. The idea is to use an SN54HC112 flip flop, wired with a Power-On-Reset in "toggle" mode, and take the output from that to the ADC input to the ESC. One press and it goes to the full circuit voltage (3.3V) another press and it goes back to 0V. Then in the VESC programming utility I can establish what actual output power I want to map to "on."
Sounds good, but it doesn't seem to be working. When I breadboard this circuit I get a "blip on the ADC out line when I press the button, but it doesn't toggle between high and low the way I would expect. It pretty much stays at a middling voltage the whole time.
Any thoughts on what I'm doing wrong? (I'm very much an electronics novice, so this is likely me just being ignorant...)
Thanks!
