Posted on August 23, 2017 at 14:42Hello everyone,I am trying to test the communication between the two SPI modules of my board. The master (SPI1) must sent an command to the slave (SPI2). If the command is 0x31 the slave must send back 15 Bytes of d...
Posted on August 28, 2017 at 17:40I want to implement a slave I2C interface with STM32F411.I can't know in advance how many bytes are going to be written from the master, or how many bytes are going to be read.I followed this approach:check in HAL_I...
