I am in the process of writing firmware for an event driven IoT device and find the visual representation of a flow chart a great way to do see how my code needs to work (sudocode essentially).
I'm struggling to find a program/service that I like and appears fit for purpose.
My question is:
Do you have any recommendations for a flow chart/control system planning program to help visualise firmware development processes?
Beyond that which you might have already tried out, I have no recommendation because my IoT/MCU device tinkering is rudimentary to say the least and pencil/paper is adequate.
