When i debug SPI1 on STM32F407, program will jump to 0x00 when write DR register, MCU reset and loop continuely. when i measure the SCLK signal using oscillator, SCLK is always high after SPI1 is enabled When i write to DR of SPI1, the code jump to ...
Hi,I am using SPI on STM32H74II MCUFirst I am using a software NSS and not a Hardware NSS because it doesn't work.I need to transmit 1 byte and receive 1 byte, the two commands one after another see the simple code below : RFID_SS_ENABLE; statu...
Dear All,My customer using STM32F205ZG and I have the following issue.I am accessing dual port memory using FSMC function, but when I measured the waveform, I found that CE(CS) did not increase due to BUSY(WAIT). See picture below.setting value : "Ad...

I am using STM32L496ZGT6P. When using DAC along with DMA to generate voltage and frequency of my desired range. But I am unable to get hold of the frequency setting. Sysclk I set is 4Mhz. 20 is prescaler value, 4Mhz/20 = 200000.This is further divide...
I found a issue.if the code isHAL_PWR_DisableSleepOnExit();HAL_TIM_Base_Start_IT(&htim2); it will stop at "if (IS_TIM_SLAVE_INSTANCE(htim->Instance))", but i didnt set break point at here.if i change code：HAL_TIM_Base_Start_IT(&htim2);HAL_PWR_Disable...
Hello,I am trying to make STM32F020c8t6 enter boot loader by connecting the Boot0 pin to HIGH via a 10k as given in some forms and pressing the reset. I connected the MCU UART1 to Laptop running Cube Programmer and use the UART option. The MCU uart1 ...
The U2 on my STM32F407G-DISC1 is shorted and needs to be replaced.Is the STM32F103CBT6(U2) pre-programmed, or can I just replace it with a new blank STM32F103CBT6 and it gets programmed when you DFU firmware the STM32F407G-DISC1 board.Hardware isn't ...
Hi,I'm trying to run STM32F429 using LL library to send data periodically.as a start, i'm sending 1 char every 1 sec, but i'm receive a wrong char (i send 'A', i receive something not clear), and when i call my custom systemClockConfig function, th...
Hello,I often have problems in using ST website. It is often slow or even unusable.For example, today I'm trying to download the CubeMX library for the L0 platform and it failed 5 times, it worked (slowly) only after changing the internet connection ...
