Try to implement an atomtic operation to avoid a specific interrupt generated by GPIOB GPIO_PIN_8 . If using the code as below, it works.HAL_NVIC_DisableIRQ(EXTI9_5_IRQn); //atomtic operationHAL_NVIC_EnableIRQ(EXTI9_5_IRQn); But tried the code as...
Hi, I'd like to play music through i2s interface using external audio codec.Refer to "STM32F4xx Reference Manual", Below setting is needed if MCLK is enabled on 48Khz FS.PLLI2SN : 258 PLLI2SR : 3 I2SDIV : 3I2SODD : 1After I configured above, BCLK and...
I have a design in which I am using an STM32L152VDT6 processor. The first prototype boards arrived, and one of the first things I noticed was that there was a resistance of 120 ohms between VCC and GND. I knew something had to be wrong at that point....
Hi,as the title says, I´ve tried sending a OD object (vendor ID, for testing) via CANsend and filling the buffer with the object. I´ve have nothing in response.I´ve also filled the CANsend function with the apropiate code to send data via CANsend()....
I 'd like to use a GPIO of STM32 to generate a clock for other peripherals. This clock should have the same precision as HSE.Also, the clock should be stable.Also, once set successfully, its stability is not disturbed by running code/interrupts.And i...
I am following this tutorial to debug a hard fault <timestamp 20:00>. I found that it is a bus fault and tried to access the BFAR register to see the address access that triggered the exception. But the address<0x1826852602> it was pointing didn't ma...
I need to change the working mode of the DMA from the general mode to the circular mode, but I don't know if HAL provides a modification method, or other modification method
