Nothing Special
Modification of mbed-src library only for STM32F030F4, very cheap microcontroller in 20-Pin TSSOP package, with 16Kbytes of Flash and 4Kbytes of Ram. **Target for online compilator must be Nucleo 32F030R8.**
Dependents: STM32F031_blink_LED_2

STM32F030F4 pinout and pin functions supported in mbed library.
other pins:
1. BOOT0 - GND
4. NRST - STLINK on Nucleo (CN4 pin 5)
5. VDDA - +3.3V
15. VSS - GND
16. VDD - +3.3V
19. SWDIO - STLINK on Nucleo (CN4 pin 4)
20. SWCLK - STLINK on Nucleo (CN4 pin 2)
GND -- STLINK on Nucleo (CN4 pin 3)
Remove jumpers CN2 on Nucleo when programming STM32F030F4 flash or debug.
tested:
- Serial (PA_2, PA_3), (PA_9,PA_10)
- PwmOut PA_4, PA_6, PA_7, PB_1
- AnalogIn PA_0, PA_1, PA_2, PA_3, PA_4, PA_5, PA_6, PA_7, PB_1
- HSE with xtal 8Mhz + 2*22pF (auto detect ok)
- i2c (PA_10, PA_9)
untested yet:
- spi
issues
- baud rate not exact (because 3% error of HSI) (Frame errors on PC side). But HSE with 8Mhz xtal does not help. Usart clock is HSI regardless use HSE?
