Hi there, I'm using the SAI2_FS_A signal to trigger a capture event on TIM2 (Through a series of weird internal routing). It all works nicely when SAI2 is an asynchronous master, however in my application it needs to be a synchronous slave to SAI1. I...

Hi there, I'm using the STM32H7 and I need to get one of the SAI FS signals to go through a pre-scaler and trigger a capture compare on TIM2 CC3.The only solution for this seems to be to use SAI2_FS_A -> TIM5_ETR1 -> TIM5_TRGO -> TIM8_ITR3 -> TIM8_TR...

Hi there, I'm using the STM32H7 to talk to a CS2000 clock chip over I2C. I'm using interrupt mode.I'm just trying to read the chip's ID register for starters. Despite the CS2000 ACKing the first 'setup write' byte, it won't write the second byte (wit...

Hi all, I am porting a c++ project from the STM32H7 EVAL board to the STM32H7 Nucleo 144.The project uses CubeMX to generate the project, then I port in all the source code and set the c/c++/linker directories, symbols and settings.The project uses F...

Hi all, I have a C++ project running fine on the STM32H7 EVAL board that I need to port to an STM32H7 Nucleo board, because it closer resembles the final hardware I will be using. I generated a Nucleo project using CubeMX and added all the things I n...

I have the same problem on the latest version :|

I got this to work by manually enabling the relevant interrupts of timer 2 (There's probably a nice way of using HAL for this..):TIM2->DIER |= 0b1001000; TIM2->CCER |= 0b100000000;and starting the capture compare with HAL:HAL_TIM_IC_Start_IT(&htim2...

Argh I thought I had solved this for a minute, but actually I don't think I have. I added the following line to enable the Capture compare:TIM2->CCER |= 0b100000000; And I suddenly got the CC3 interrupt, but I think it was actually the output compar...

Thanks for the reply, JW.I am checking by reading the TIM2 registers and nothing is appearing in CCR3, despite the counter running. I also have TIM2 CC3 interrupt enabled (That's how I will be reading it eventually), and it never fires. I enable...

Well, I managed to get it working by setting the interrupt priority to 0. The problem is that I'm using FreeRTOS, and the interrupt will need to use the FreeRTOS functions, so the interrupt must not have a priority higher than 5.Does anybody have a...

Does the signal SAI2_FS_A not trigger when SAI 2 is in synchronous slave mode?
