Hello,
How much debug hardware helpful? and is there hardware which will be used for Arduino,Esp etc, i mean common hardware for all.
General test equipment: DVM, logic analyzer, scope.
LED and piezo buzzer for very basic tests.
I have always done all my debugging using only Serial prints and a cheap 24mhz/8 channel logic analyzer:
I've never found it necessary to use anything else.
Many thanks for quick and detailed response.
I made these, mini serial monitor and simulated LEDs. In reality it's a custom 4809 board with display and serial ports, so you can program it to do whatever you want.
depends on the problem being debugged.
there's a lot that can be done with LEDs, voltmeter and software designed for test.
...and sometimes, a second Arduino.
