Hello,I am trying to get the CAN Bus on a Nucleo F446RE to receive messages from an ECU, but it will not. The STM32 has been tested in loopback mode and is able to trigger the interrupt and process the data upon receiving the message, and the STM32 i...
Hello,In my project I need to get very low power usage device. It works with camera, so when I am taking picture I need maximum processor speed since I need to be at least 4x so DCMI could support full speed parallel data.When I am done with my calcu...
I'm trying to transmit CAN messages with the stm32f4 from CAN2 to CAN1 (using a transceiver and so on). I'm trying to put the baud rate at arround 1khz so I can watch it using my arduino as an oscilloscope (which is able of performing 3666 samples pe...
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...
