updated, this is now a 'just works' release
- first connect the maple mini with Girino stm32duino flashed/installed (libmaple core)
- then start the java Girinoscope front end and connect to it
- voltage scales
Girino maps the range to 0 to 255 - -2.5 to 2.5v, so 0v is around 128.
STM32 ADC maps the range range 0 to 4096 - 0v to 3.3v. To change the voltage scale mapping on the menu select Display > Change Signal Intepretation
The ADC (oscilloscope) input is from pin PA0 ADC channel 0 (max 3.3v)
Timer 2 is setup on PA1 to generate a 1khz signal, hence patch PA1 to PA0 for a test signal.
should work on maple mini and blue pill
