Hello all,I am using an STM32H7 and STM HAL drivers V1.2.0, SPI slave in interrupt mode.My requirements are as follows: Receive messages of unknown sizeReceive messages at any timeAbility to transmit at any timeSo far I am having the following issues...

Hi All,I am developing an application for the STM32H753II using IAR toolchain, STM HAL and Micrium OS-II.Most of the linker script files in the STM32Cube example suite only specify DTCM RAM for data storage (addresses 0x20000000-0x2001FFFF). I have b...

The slave is always sending and it asserts a GPIO to notify the master that it has something to send. The master then begins shifting 00s until the complete message is received. There is no SS or framing signal coming from the master which tells the ...

Hey Bob, thanks for the response!Your suggestion definitely helps as you've added another tool to our belt.My problem is that I am essentially queue-ing a large buffer to be received which prevents the transmit from executing. The slave needs to rece...
