So I made the decision to share the needed steps to configure it ( and also to avoid the duplication of my answer each time). The embedded DMA in these chips is a massive help in getting a project up and running without any struggle for cpu power. Here I'll do one more example with the micro's UART. So today in this post, we are going to learn how to use SPI with STM32. GitHub Gist: instantly share code, notes, and snippets. The first half of the transmit buffer is loaded with new data by the CPU in the Transmit Half Complete interrupt callback while the second half of the buffer is being transmitted by the DMA in the background. Note that we have selected the 7-bit addressing. Arduino and Genuino boards to share information with each other. HAL_I2C_Master_Receive_DMA() (+) At reception end of transfer HAL_I2C_MasterRxCpltCallback is executed and user can add his own code by customization of function pointer HAL_I2C_MasterRxCpltCallback (+) Transmit in slave mode an amount of data in non blocking mode (DMA) using HAL_I2C_Slave_Transmit_DMA(). Wiring is: PA5 -> SCL PA7 -> SDA PA9 -> OLED_RES PC7 -> OLED_DC I use CubeMX code generation tool to initialize all the peripheral. why aren't there any software SPI libraries? Because it's about 10 lines of code each for the WriteByte and ReadByte functions, and most of that is bit banging processor-specific registers.
