stm32h745 M4 Core doesn't work properly

Hello All, I have a STM32H745-DISCO board and trying to run a very simple program where M7 toggles Green LED and M4 toggles RED Led. After programming, I can see that Green LED is toggling fine but RED LED is not.Below is my simple main code: M7: int...

Is UART_CR1.TE toggle sufficient for IDLE frame generation, if UART kernel clock is APB?

I experimented with this, however, as long as UART kernel clock was set to APB, idle frame was generated, even if the two instructions writing to UART_CR1 were immediately after each other. I may have overlooked something of course.I have no problem ...

I want to make Raspberry Pie a client and connect it to the server

I want to make Stm32 a server and send and receive messages through Raspberry Pi and WiFiRaspberry Pie made a code in C languageif ((server_socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)) < 0) {   printf("socket() error!");   }   ...

Can I use the STM32 MCU as an SPI slave to emulate an accelerometer behavior?

I want to use S32G NXP microcontroller as a SPI Master and stm32 microcontroller as an emulator SPI Slave.

Hello there, we planned to use STM32L433x series MCUs, our project has Ten push buttons and five Digital Input signals, which all need to be configured as interrupts, so how many interrupts can STM32L433 series MUCs can handle simultaneously?

How to find reason for hard fault , very rarely occurring ?

the "system" is a audio player, decoding (in float) MP3 stream, output on I2S to a DAC;cpu H743 , at 200MHz, i/o by DMA1 , stream coming from ESP8266 wlan radio.system ok, running ...maybe 1..3 hours, then hang up:just now got it first time, still in...

Stop mode in stm32L552

Hi all,I am using stm32L552CE. When I enter stop mode or sleep mode, the current is too high (5mA for stop mode, 18mA for sleep mode). /* Enable PWR clock */  __HAL_RCC_PWR_CLK_ENABLE(); HAL_Delay(5000); printf("Go into stop mode\r\n"); /****** Suspe...
