I've got some code working from an example for USART RX DMA Circular. I'm to the point where I can receive the UART data but I need to now use a write to a protected (by a binary semaphore) circular buffer from the interrupt context HAL_UARTEx_RxEve...

My desire is to find some detailed documentation on the MCSDK 5.Y.1 project generated and how to exercise the motor using the Motor Pilot. Specifically:• Change the initial startup speed• Change the speed of the motor (while the motor has already...

Thanks for the hint. Changed the callback to the 'half word' callback and now I'm getting a successful 16-bit transfer with TRANSFER_COMPLETE. Now I just need to figure out why the second byte of the 16-bit received word is 0x00 instead of the desi...

Getting there. Changed all of the dma interrupts to priority 6,0 and now not getting the assert. Changed the attempt to use the semphoreFromISR to using a queue and now I'm passing the data from the interrupt to the task and input the stream into a...

I'm not dynamically switching from 8-bit to 16-bit (half-word). Just configuring the app to run either 8-bit or 16-bit transfers.I will try your suggestion to set a breakpoint in the DMA Stream interrupt and verify that the NDTR register reaches 0.

I believe that I have already tried that before I made this post. Tried it again (to make 100% sure) and got the same results as the top post with 80 and 48 decimal for cMaxSysCallPriority and ucCurrentPriority (lower number is higher priority). Do...

Let me be explicit with my questions ...Using FreeRTOS and configured is #define configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY 5 in FreeRTOSConfig.h.My goal is to set the priority of my DMA interrupt at a lower priority than the configMAX_SYSCALL_INTE...
