Hello, in my project I need to read an encoder that clocks out data with clock burst. For this I decided to use UART with clock generation and DMA. (I also mixed up RX from one UART to another , but this is not a problem if request happens at the sam...
Colleagues,I’ve made a custom board with STM32L082KZ. I was able to upload firmware and debug for several days. But today I can’t upload firmware, and the NRST pin is acting strangely.The setupI’m using ST-link V2 and STM32cubeIDE 1.13.0 .My entire b...
Hi, for a STM32F303RE I configured a pin as an ADC input. I want to use the pullup/pulldown resistors as a voltage divider for an offset voltage. I tried to switch on both in ADC mode, that did not work. Everything is fine with the pin configured as ...
The ADC counts returned by the internal temperature sensor appear to depend on the sampling frequency. In other words, it looks like the temperature sensor can be read too fast (with or without oversampling) to give incorrect temperature readings. ...
Hi all,I have an system that reads data form an external ADC via SPI DMA, i send the StartConversion CMD and when it's done i get and IRQ so i can read the register. I also have an UART communication that polls every 2sec for the new data, I have the...
The LED connected to the Blue Pill board on PC13 pin blinks after power up. Just to check the pulses on that pin, probed and seeing the attached pulses. Why are these pulses generated? I haven't seen any data about this in any of the documents? I did...
Hi,I have been able to use the option bytes to configure the Nucleo-G0B1RE to jump straight into the ROM bootloader on powerup and I can see the DFU on Cube Programmer, however on our target board with a G0B0 using the same user option bytes settings...
Hello Community,We are using MEMS OScillator for the clock source for STM32G474 MCU. And are unsure if we can use the OSC_OUT pin as a GPIO pin when using the MCU in Clock Source BYPASS mode.The datasheet mentions we can, I, however, would like to co...
Hi,I was following @Laurids_PETERSEN post on his low power ThreadX example (Part 2 ThreadX Low power Project ). I noticed his sample code, Snippet 11 on Enter Low Power mode configured the APB ENR, AHB ENR in RUN mode and then disabled all the periph...
