Hi,I working with STM32L433's ADC, and I'm having a problem where the ADC CH11 couldn't coexist with other GPIOs. I'm using a resistor divider from a battery and feeding into ADC1 CH11 (PA6, pin16). If the PA5 is left in a reset state, it all works. ...

Hi,I'm using STM32F429 to talk to TI BQ40Z50 via I2C, and I ran into an issue I have no clue.First of all, the code simply reads registers, and it works on TI BQ20Z95. The same code doesn't work on BQ40Z50. The HAL library always returns HAL_BUSY, an...

Hi,I'm using STM32F429 on a product. I'm doing a device firmware upgrade using the BFB2 feature. The exact steps I'm doing are:Boot from Bank1 or Bank2Erase the inactive BankWrite new FW to the inactive BankToggle BFB2Soft reset (NVIC_SystemReset())I...

Hi, I'm using STM32F429 to build a prototype. I found my board couldn't enter the USB bootloader mode. What I found was: Connect Boot0 to 3.3V via 100k ohm resistor, no pull down on Boot0. The MCU could enter USB bootloader mode properly. I can see a...

Hi,I'm wondering if it's possible to freeze the IWDG in stop mode for STM32F429. I couldn't find this option in the STM32CubeProgrammer. Not sure if this is feasible.Thanks,

Thanks to both of you. Turns out the issue was my poor soldering job. The surface wasn't clean enough. My best guess is the flux is somewhat conducting. After wiping out all the debris, it works as expected.

Hi Bob,Thanks for the insight. it was indeed the internal pull-up issue. it works great with external pull-ups.Thanks!

Hi JavierI found an alternative method.STM32CubeMX could generate a makefile, which is easier to work with Github actions. However, the auto-generated makefile doesn't work straight out of the box. Some minor tweaks are required to compile the proje...
