Dear ST Team, could you please update this section with correct information?There is incorrect text description or figure in RM0454 Rev 2 in section 14.10 (VBAT).Text: "...converted digital value is half the VBATvoltage."Figure: VBAT/3.
Have tried both Chrome and Edge and unable to access e-learning catalog courses. Keep getting same below error the last two days
I am from China,I was told that STM32 hardware I2C has bug.So I always use software simulation I2C with two ordinary GPIO Pins. I was wondering what is the bug exactly?Is it a rumor ,or is it true?I hope get opinion from abroad website,because you sp...
I've been tinkering around STM32 (L443VCT6) for a couple of weeks now and one thing I don't get is I'M USING THE ADC_IN 10 CHANNEL. MY ADC MEASUREMENT REMAINS THE VOLTAGE RANGE ON THE PIN LEGS, HOWEVER, MY ADC VALUE IS INCREASING. AFTER 4095 IT IS NO...
I am trying to encrypt part of my code and write back to internal flash. The MCU is STM32F407 and write to flash sector 3 (0x0800C000 - 0x0800FFFF). I customized the sct file to avoid other codes taking the place.The encrypted data takes 1Kbytes and ...
Hi guys.I have 2 GPIOs, one is used as a PWM, the other one is used as ADC.and the peak comes in the falling edge of the PWM singal.and the plus width is only like 2us.I want to get the value of the peak voltage using ADC.The problem is, if I use a i...
Hi everyoneI'm trying to get the ADC1 running with a DMA transfer on the STM32H757ZI. The goal is to measure 10 channels with 8 samples each and transfer these measurements to a separated SRAM1 buffer with DMA, each time the conversion sequence has b...
