HAL SPI nested interrupt race condition with overrun in IT mode transfer
Issue detailsWe have observed a situation where a full duplex HAL SPI transfer in IT mode would hang in permanent BUSY state after many transfers in a system with relatively long ISRs at higher priorities than the SPI.Debugging showed that the lockup...
We want to use 12 PWM synchronous signals. It means, all PWM shares the same clock cycle and runs at the same time without making any clock cycle delay using HRTIM and TIM1 timers.
We want to use 10 PWM from HRTIM, 2 PWM from TIM1. However, we don't know how to synchronize these two timers. We can synchronize all PWM signals of HRTIM but could not do it with TIM1. We need one master clock and others (12 channels) as slaves. Ple...
Resolved! Cannot get valid values using ADC1 channel 11 on PC1
Hello,I'm using a Nucleo board (NUCLEO-G070RB) with STM32F103RB MCU and I try to use channel 11 of ADC1 mapped to PC1 to get values from a humidity sensor. I noticed that the values are invalid and it's not because of the sensor. I created a sample a...
Resolved! FIFO Error on DMA with SPI_TX (STM32F411E-DISCO)
Hello Everyone, I am trying to transmit data using DMA with SPI1 but each time I end up with a FIFO Error.. I 'm using Direct mode, MINC = 1, PINC = 0, DMA2, STREAM3, CHANNEL 3 For SPI_TX. I'm trying to send "Hello, World!!" But each time the FEIF3 i...
STM32F103RET6 - Not work callback - HAL_CAN_RxCpltCallback.
Hello. I have project from 2 years ago. During testing, a problem was discovered when sending commands from the master device to the slave device through the CAN. For some reason don't call callback - HAL_CAN_RxCpltCallback (there I analyze the incom...
COMP2 and EXTI does not seem to work using HAL (STM32L452)
Using COMP2 with internal voltage referenceWhen using COMP with interrupt as soon as I call HAL_COMP_START(&hcomp2); and interrupt is triggered even if COMP input GPIO is grounded.If i let the code run a trigger is never regenerated afterwards. I hav...
Resolved! About IPSR
I use STM32F1 Value Line Discovery Kit.I would like to have a common interrupt handler and call the corresponding handler from that common handler.I am assuming the following.Specifically, I am trying to get the IPSR number from its common handler an...
Resolved! STM32H7 DMA2 wont trigger interrupt
Using STM32H743ZII am using SPI1 in 2 lines Rx only mode with DMA2 Stream 2 as in ST exampleI use Rx DMA with a buffer located in D2 RAM. Using debugger I found that the first reception works well, data gets written into my buffer. But my DMA doesn't...
