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...
Hello,I activated TIM6 and TIM7 in interrupt mode. In the elapsed call back function, I checked TIM7 with toggle function, and it works. But when I place switch-case related functions. It didn't work. Could you check it what I missing?Thank youvoid H...
Some info: Working with the CR95HF NFC Reader/writer. NFC tag is a Mifare Ultralight EV1, ISO14443A type 2 tag..My current anticollision sequence is as following (I send the commands with sendreceive of the CR95HF library):REQA "2607" ATQA "800544002...
I believe I found a bug in the eeprom emulation for the stm32h7 in the \STM32Cube\Repository\STM32Cube_FW_H7_V1.3.0\Projects\STM32H743I_EVAL\Applications\EEPROM\EEPROM_Emulation\Src file eeprom.c. The EE_ReadVariable returns erroneous data. line 426 ...
Posted on May 08, 2018 at 14:00Hi, I was just started with CAN peripheral on my stm32f446re nucleo board. The problem i am facing is HAL_CAN_Init() added by cubeMx code generation software is failing at the below line of code it is returning HAL_ER...
Hi,I've set up a PWM with TIM14_CH1 on pin PB1, using standard peripherial library and this worked fine (the signal on the output-pin was just as expected).Now I've tried to move the PWM signal from pin PB1 to PA4, still using TIM14_CH1, but with no ...
Hi all. I'm trying to find the source code for the HAL function HAL_ADCEx_Calibration_Start(). I'm working with the STM32L152. I've downloaded the latest version of STMCube (STMCube_FW_L1_V1.9.0), and looked in stml1xx_hal_adc.c and stm32l1xx_hal_adc...
Hi, STM32H7B3I-DK is already in stock at Digikey. Someone from ST could tell us when the STM32H7B3I-DK and Microcontroller documentation will be available on the ST website?
