The chip is STM32G491. The NRST pin is suspended. The option byte is default value.I find my board doesn't work after power up, so I measure the waveform of VDD and NRST as figure 1 below.Figure 1The green wave is NRST and the yellow wave is VDD. The...
I'm trying to generate periodic interrupts with an LPTIM on an STM32H723. I'm using HAL_LPTIM_Counter_Start_IT() from the STM32H7xx_HAL_Driver. My interrupt handler is never being called. I've confirmed that my interrupt handler is in the vector tabl...
I am sending an audio stream from memory to SAI2 on an STM32L476JG. There will be moments where I disable the DMA based on external asynchronous events. Can someone tell me the appropriate way to then reset the DMA so that when it begins again it i...
I am using STM32F429ZIT6 - NucleoMy application needs to generate pulses on specific encoder position like this : I was able to setup TIM2 Channel 1&2 in encoder Mode, TIM2 Channel 3 Output Compare (no output) as master to TIM1 Channel 1 in One pulse...
Hello,I have a very straightforward question but I am not able to find the answer in the user manual. I am using the L476RG nucleo board and setting the TIM5 registers to output a PWM. How can I select the output pin? Is it fixed or does it have som...
In a previous project, I configured the PA0, PA1 PA2 inputs as ADC and read them with DMA without any problems. Since I need to use PA0 and PA1 for another job, I shifted the ADC inputs to PA7 and PB1. but I was not able to read these channels with D...
In all the STM32s that have I2S / SAIs and ethernet that I've checked, there is this fixed oversampling ratio of 256 between master clock and sampling rate.When using the internal PLL to get the sampling clocks, no problem (amazing how good and stabl...
Firstly, I have a can transceiver that worked in STM32F7 nucleo board with interrupt mode configuration. So my transceiver works properly I guess.Now, I am trying to configure H743ZI2 to create normal can frames. My setup is 2 H743ZI2's and used same...
Per the title, I'm using USART2 with DMA transfer but for some reason the line stays LOW (active) before/after transmision.Init code is pure HAL generated, I added a "DeInit" just to make sure the UART enable wasn't persisting between resets/debug se...
I wonder whether I can connect two quad spi ap memory to the same octospi interface on stm32h730 to double the bandwidth. Or such a configuration can only be used with nor flash, not psram. Thanks.
