Posted on January 03, 2018 at 19:25I recently had a problem in one of our designs that was caused by assigning a GPIO with an external pull-up to PB2 on an STM32F413. It turns out that this pin has the additional function of being BOOT1, so the pull...
Posted on March 07, 2018 at 22:43I am using STM32L053 and Keil IDE. I have imported FreeRTOS from CubeMX. Is there a way I could disable the FreeRTOS and enter into standby mode? Then, wake up on GPIO signal (external interrupt). And when I wake up,...
Posted on November 03, 2017 at 17:53Hi,I work on design with STM32L452RET6P and I'm considering power managment. I've got some voltage regulators that needs high voltage on SHDN pin and i want to use GPIO to keep this regulators on. I have read data...
