SPI DMA library allows you to send and receive data via SPI in non-blocking mode. It can be use for TX only, RX only or both (transmissing mode). This library is extension for my SPI library. It requires SPI library as basic to make this to work. Library Read more about HAL libraries Features SPI extension for non-blocking TX, RX or both modes Supports all SPI peripherals on STM32F4 and STM32F7 device Supports interrupt processing Allows you to start DMA transmissing and wait till done This is...

Next library in ported libs is SPI for HAL based drivers for STM32F4xx and STM32F7xx based devices. Library Read more about new HAL libraries Features Operate with up to 6 SPI peripherals Send single or multiple bytes at time Automatic SPI prescaler selection based on maximum clock selected for your external device Software based Chip Select pin Support for custom GPIO pins combination for SPI
Let’s say something about SPI. SPI (or Serial Peripheral Interface) is a protocol named by Motorola. With him you can control sensors, SD card and much more. SPI protocol works in a ways where there is one master and multiple slaves, In other words, master is our STM32F429 Discovery board and let’s say, SD card is slave.
