Hello,I'm currently working on a project where my STM32G747RE is acting as an SPI Slave.The SPI transmission is as follow:Master sends 8 bits "command"Slave send back 16 bits "data"My issue is the following; On the MISO line, the STM32 always send ba...

Hello,I'm currently using the HRTimer (on a STM32G474) for duplicating a input PWM signal. That means that in my case, I have one PWM input coming on 2 events (1 for the rising edge, 1 for the falling edge) and the outputs of the HRTimer B, will be s...

Hello,I'm trying to build a setup to test SPI communication between a master and a slave.The master side works well, when the master ask for a read, it sends a byte of register address and ask for 2 byte of reading (I can see 16 clock ticks for the r...

Hello,I'm planning to use the STM32G474 to read a pulse width. This width is a delay value in nanoseconds.I'm wondering if there is any possibility to use the High resolution timer (HRTIM) for that operation.I would use the events to trigger a rising...

Actually, I discover that my SPI TX FIFO was outputting his value when I'm reading the first byte. That means I need to empty it or put 0xFF inside of it. One way to do it is:HAL_SPI_Abort(&hspi2);__HAL_RCC_SPI2_FORCE_RESET();__HAL_RCC_SPI2_RELEASE_R...

You are right those are the 2 main parameters, but it is not going to change that in a certain way my FIFO is filled with previous data values and then send during the receiving operation.

Alright, and about"If you want MISO to be high or low, treat it as a normal data byte and write 0xFF or 0x00 to it on the slave side."What should I do, modify the registers or config values of the SPI2 or just expanding my sbuffer_tx ???

I can accept the idea behind "dummy bytes" but here we really want to control what is getting on the MISO line.But on my setup the MISO line signal get through several drivers before ending to the master, that means that the signal can only go from t...

It was just the fact that I was not using the DMA with the HRTIM, so all the callback functions were not enable.Thanks for the RM file, it will be very useful.Kind regards,Chris

STM32G4 SPI Transmitted Data is also Transmitted while receiving during next cycle

Triggering the input PWM or output PWMs using the HRTIM on STMG4

STM32 Master to STM32 Slave SPI communication - Slave doesn't respond back

Is there a possibility to read the HRTIM timer value ?
