Hello. Please tell us how the microcontroller programming process works. The controller can be programmed in two ways, fill the firmware through the bootloader and through the programmer.If in the first case there is microcode on the controller that ...
I am using memory mapped mode of the QSPI peripheral on an STM32L452. I can see in the memory view at address 0x90000000 the bytes i expect. However, when dereferencing the pointer to that memory all i get is 0xFF's. In the attached photo you can see...
I have many problems using the CN7 connector (pin SDA/SCL) with external I2C FRAM and I2C DAC chip.There are no problem using the EXT/RF E2P connector (pin EXT_SDA/EXT_SCL).Why ?
Hi everyone. I'm a novice so have patience with me. I have a stm32f103c8 (blue phill) card connected to 8 HC-SR04 ultrasonic sensors. I use the STM32Cube IDE. I already have the program ready to read the distances in all the ultrasonic sensors. Now I...
Arm_correlate_fast_q31 takes almost twice as much time as arm_correlate_q31.Am i missing something? I measured the calculating time for arm_correlate_q31 for various block sizes and then simply inserted the "fast_" in the function call and it takes a...
I wanted to generate PWM Waveforms with nucleo F411and found a severe bug in the hardware. Maybe it is described in the errata sheet, but I found nothing.bug:DMA is dependent on data send on DMA stream. Sometimes DMA transfer is not done. (DMA circul...
Hi, I am using an STM32F407VGx MCU and I am trying to receive data from SPI1 using DMA.STM32CubeIDE generated code for the SPI1 is the following:void MX_SPI1_Init(void) { LL_SPI_InitTypeDef SPI_InitStruct = {0}; LL_GPIO_InitTypeDef GPIO_InitStr...
HiI use STM32 NUCLEO-F746ZG development board for my project. I split the ST-LINK and target STM32 part (Cut PCB). I tried to use HSE on-board oscillator from X3 crystal. I soldered the NX3225GD-8.000MEXS00ACG04874 8-MHz crystal oscillator and two 4....
I am using the STM32L412C8 and I am having trouble with the USART2 RX/TX pin swapping. I enabled it in CubeMX but if I send data to the PA2 pin (originally TX but should be RX after the swap) I get nothing. If however I send my data to PA3(should be ...
