ST32Cube_FW_H7 V1.5.0 Nucleo H743Zi code for LED2 doesn't work.

I used ST32Cube_FW_H7 V1.5.0 Nucleo H743Zi example code for Nucleo H743Zi, the LED2 doesn't work, I thought I got bad module, then I order again, second Nucleo doesn't work too.

trouble with stm32f334r8 ADC which goes in to the unknown state in very weak noisy environment.

I am using stm32f334 in a power conversion project.I have configured its ADC in  independent mode and transfer its data by two channel DMA.some times in a even very weak noisy environment the ADC goes into the unknown state. I checked all of its regi...

Using Select() to get non blocking Tcp recv()?

Anyone already used select() function together with a timeout? I like only to call the Tcp recv() function when data are in the receive buffer.I have a Nucleo F429Zi.With best regards,Jens

Receive Data from UART's

Hi thereI have a question..I have 6 Laser Sensors and I want to receive the data via 6 Uarts and then send all data via the 7th Uart. Every laser sends 4 Byte of data. Start byte starts with 1. ​My questions are:how can I make a array of buffers? I n...

How to flash code into STM32 F401RE NUCLEO

SWD programming / debug interface on the STM32L073 - SWO??

The STM32 STM32L0x3 ref manual (RM073) and STM32L073 datasheet both show only 2 pins for the SWD programming interface:- PA13 (SWDIO) - PA14 (SWCLK)But the schematic for the STM32L073 Nucelo PCB shows PB3 connected as SWO.I dont see any reference to ...

Is it possible to send word(2 byte) data through UART when we set data wordlength of 8 bits???

Hi,I am using STM32F446ZE NUCLEo board. This board has many uarts and the Data Register is of 32 bit wide but maximum can be used is 9 bits, others are reserved.I have configured one UART channel UART5 and I am able to send series of byte data from m...

STM32 mktime() function has the 2038 year bug - where is source code?

Hi,We use an RTC and the POSIX function mktime() to convert a broken-down time into a time in seconds.Function prototype: time_t mktime(struct tm *tm);Problem is: this mktime() function has the 2038 year bug (see here https://en.wikipedia.org/wiki/Ye...

STM32H747I-DISCO working temperature

Hello, I want to know the working temperature of STM32H747I-DISCO. I need some STM32 device with a touch screen and a MCU in it. Is there a such device that can work in extreme temperatures such as (-40 Celsius to +60 Celsius) ? Thank you beforehand.
