The Controller Area Network (CAN, also known as CAN Bus) is a vehicle bus standard designed to allow electronic control units and devices to communicate with each other in applications without a host computer. STM32F779-Eval board has 3 CAN interfaces, however only the two of them have their own clock (master). For that reason the following library provides some C methods to activate and use...
USARTx DMA ring buffer for STM32F779-Eval board
I have recently been playing with UART and DMA, although i’m still getting my head around it,. DMA allows you to transfer large amounts of data through the system without getting the processor core involved. Rather than the CPU laboriously reading a byte, the writing a byte from one buffer to another, you’d give the DMA controller a pointer to the start of a source buffer, a pointer...
Using the SD Card of STM32F779NI-Eval board
Are you in need of an additional memory larger than EEPROM? Although EEPROM is a very easy and effective way of storing data on the board, the built in EEPROM only offers only a few bytes of storage. When working with larger or more advanced projects we may need to store additional data so an external memory solution. For that reason, MicroSD card enables you to do this quickly and easily. The...
