Hi.I am trying to configure a timer with PWM in one-pulse mode (TIM5) as slave of another timer that sends N pluses to trigger TIM5.I am unable to do it could you give me a hand to understand what I am doing wrong?TIM1 when started should triggers an...
I am trying to use the HAL driver - HAL_I2C_MEM_READ(....)The stm32 is the master and there is a slave i2c device that I want to read from. The I2C transaction goes like this: <start> <dev address> <register that I want to read address> <start> <dev...
Hi,i tried the SAI_AudioPlayback example for the h745 discovery board. I'm using Keil and with the keil 5 armcc compiler everything works fine.Now i switched to armclang 6 and replaced the "libPDMFilter_cm7_keil_wc16.lib" with "libPDMFilter_cm7_gcc_w...
I have an STM32H745xx dual-core microcontroller, and want to use the Memory Protection Units (MPU) in each core for functional safety. The goal is to prevent the M7 core from accessing GPIO, Flash, and RAM that is dedicated to the M4 core.I can confi...
HAL_SPI_Receive_DMA() is non-blocking; it just sets up and starts a transfer. Is it safe to call it from an interrupt context?If it is (at least possibly or sometimes) safe, does it make a difference whether the SPI port is configured as SPI_MODE_MAS...
Hi, I am working on a project using STM32L152. I have ADC DMA set up as I've used in many other projects using this part. For some reason this time around ADC values are not getting ready by the micro, and when I debug I find the DMA1_Channel1_IRQHan...
I have created a bootloader and application. My bootloader appears to launch my application successfully; however, the interrupts are not functioning in the application. I used memcpy to copy the vector table into RAM. Below shows the results of th...
I know that they can not be used at the same time. But how can you switch between CAN and USB at runtime in the same application?
The example does not work. It times out:Stack:HAL_OSPI_AutoPolling() at stm32u5xx_hal_ospi.c:1,831 0x80042e8ospi_memory_reset() at lx_stm32_ospi_driver_glue.c:560 0x8001afelx_stm32_ospi_lowlevel_init() at lx_stm32_ospi_driver_glue.c:79 0x800165alx_st...
