Example for using Nokia 5110 Screen PCD8544 in DMA mode on STM32F103REY6.
Added software to make a STM32SCOPE.
Image of screen shoot with 2 signals and means voltage of the displayed signal.
- Dumbass means voltage
- Dumbass trigger (voltage based)
- Clever trigger
- Frequency counter (period)
- Clever means voltage (between 2 periods)
- Measure Min, Max, Peak to peak
- +Width, -Width, Duty cycle, rise, fall period
- Change time base
- Change voltage base (may with better hardware ?)
- Voltmeter, Ammeter, Ohmmeter Capacitance meter....
- Battery tester
- LRC Meter with ESR ?
- More options ?
