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...
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
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...
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 ...
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...

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...
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.
Hello,We use a CR3032 Lithium battery to backup the clock and do intrusion detection during power down of the machine. We just connected VBat to the battery. UL told us we would need to protect the battery from reverse currents. For this we would nee...
