AN4221 says it will enter I2C boot mode on detecting its address and will then start waiting for commands. What is not clear is whether this address is sent as part of the first command, or by some separate undescribed operation. I've tried various a...
I want that the user can design the screen at runtime. So I'm trying to add box, text, image to the screen by the user button. I tested font caching for the text and didn't know how to add the text and where it should be. Even the text is cached, ho...
So we have just gone into production on a new design, a very small part of the circuit monitors the devices battery voltage fed into one of the ADC channels. I am finding that 1 in every 50 boards has developed a failure with the ADC where it just re...

Dear ST Community,I would like to set up the USART1 and DMA2 in a way, so that the DMA automatically stores the data received by the USART to a buffer variable.To achieve that I used STM32CubeMX to generate the configuration code utilizing the Low Le...
Everything works until I get the JSON from location.io via curl.By using the first 22 bytes of the seed, eg AAQAJsX0iCbF9IgAAAAAJs, I always get the string $PSTMSTAGPSSEEDBEGINERROR*10 after sending each one of the following strings:$PSTMSTAGPSSEEDBE...
I met the same issue with this topic:https://community.st.com/s/question/0D53W00000bghNqSAI/fail-to-get-required-stm32cube-firmware-packageI tried "Refresh", it was still there.
Hi everyone,I am using comparator 2 to capture a signal of duration 3-5usec. But observed that, I am able to trigger the comparator only when the duration of the signal is >5usec. I was wondering if there is any delay introduced by Vrefint in STM32L0...
