The timer (TIM3) has been introduced as a source of interrupts. Thrid LED was added and connected to PA9 pin (TXD pin on UART header). Pin func init () Ĭhanges compared to the previous example: Package main import ( "delay" "stm32/hal/gpio" "stm32/hal/system" "stm32/hal/system/timer/systick" ) var led gpio. If you want to follow subsequent steps of this post, you need to install Emgo After brief study of RM, the STM32F0 series appeared to be striped down STM32F3 series, which made work on new port easier. There was no support for any F0 MCU in stm32/hal before this board arrived to me. I’ll use Emgo, but don’t worry, you will see that it gives you as much Go as it can on such small system. You must face the truth: there is a negligible chance that someone will ever add support for Cortex-M0 to the Go compiler and this is just the beginning of work.

If you hoped to see how to use genuine Go to program this board, you need to read the hardware specification one more time. As you can see, it is very small 32-bit system. ADC, SPI, I2C, USART and a couple of timers,Īll enclosed in TSSOP20 package.CPU: Cortex M0 48 MHz (only 12000 logic gates, in minimal configuration),.The STM32F030F4P6 is impresive piece of hardware: Thirdly, I chose the smallest member of the family for the purpose of this article, to make the whole thing a little more intriguing. MCUs belonging to the STM32F0 family are just as cheap if not cheaper and has newer peripherals, with many improvements and bugs fixed. Second, the STM32F10x series is getting old. First, I have never dealt (as a programmer) with STM32F0 series. I recently bought this ridiculously cheap board: How low we can Go and still do something useful?
