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.** 01.02.2018 Acosinwork: Fork of mbed-STM32F030F4 library. Support for Troyka GPIO expander by Amperka. http://amperka.ru/product/troyka-gpio-expander
