STM32 MCUs Products

We are using LAN8742A with an STM32F429 microcontroller. Ping is not happening. it showing destination host unreachable. Same hardware design and software code is working with Eval-Board STM32F7058-DK. Need some clue for where to look for errors.

I have check the REF_CLK_OUT, CLK_IN, and MDC. This is same in both the boards

Hello, I want to study and implement FOTA (Firmware over the air upgrade) on STM32F103RB. Can anyone suggest me proper documentation on how to proceed and which tutorials to study???

Using indications instead of notifications with BLE

Hello,I have a question regarding implementation of BLE on proteus and nucleo boards.I am struggling to understand how confirmation of indication is processed by the server (and also how does client provide this confirmation). There doesn't seem to b...

Hex or bin with multi-firmware

My solution have more than one project, each project program in different address. exp: bootloader(0x08000000, 64K) application(0x08010000. 448K).How can create an hex or bin with these two ?

connect two stm32 board using uart

Hi, may I know how to connect two stm32 board using uart?Im using nucleo g071rb to transmit the data to STM32H750-DK. So basically i just want to try simple application using serial but it not successful.so what i want to do Nucleo G071 transmit data...

Waveform Non Pin Timer GPIO STM32F429IGTB

Hi All,I want to generate digital clock/waveform at non timer pin STM32F4219igtb, let say using pin PORTD.5 and synchronize with several GPIOs using DMA. the purposed to drive the multiple HUB75 port.Currently i'm succeed to drive the clock pin using...

How to toggle GPIO using the "PWM Generation No Output" Timer mode ?

I have a use case where I need to toggle a GPIO based on a PWM waveform. Since the GPIO chosen doesnt fall in the PWM timer pins, I have to toggle the GPIO in some other way. I came across the timer mode "PWM Generation No Output" mode. I am thinking...

I have a button connected to STM32F405. I am using external interrupt with the button. Inside the callback of the external interrupt I am sending a command to retrieve some data from another microcontroller as a loop. But I am receving only data once.

void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if(GPIO_Pin == GPIO_PIN_10) { for(volatile int j = 0; j<3000; j++) { char Txbuffer = "Read\n"; HAL_UART_Transmit_IT(&huart2, (uin...
