mbed-dev library fork for STM32F100R6 microcontroller (LQFP64, 24MHz, 32kB flash, 4kB ram, 2-channel DAC, HDMI CEC, very cheap) . Use in online compiler (instead mbed library) with selected platform Nucleo F103RB.
Fork of mbed-dev by
Tested and working:
- blink
- system frequency 24Mhz (with external xtal 8Mhz)
- stdio uart on pins PA_2-PA_3
- Serial on pins PA_9-PA_10
- AnalogOut on pins PA_4, PA_5 (DAC)
- AnalogIn on pins PA_0, PA_1, PA_2, PA_3, PA_4, PA_5, PA_6, PA_7, PB_0, PB_1, PC_0, PC_1, PC_2, PC_3, PC_5, PC_5
Notes:
- TIM2 is used for mbed needs (eq Timer, Ticker, wait etc. )
