Resolved! LoRa-E5 STM32 WLE 5JC: How do i set a GPIO pin back to Analog to save power?
BQ_GE_GPIO_Port->MODER = GPIO_MODE_ANALOG;//setting to analog to save powerThis seems to not work at all. I have a physical pulldown on the pin but the pin stays HIGH. Why is that?i init the pin via this code here:__HAL_RCC_GPIOB_CLK_ENABLE(); GPIO...
STM32CubeMX Power Profiler on STM32WB BLE Configuration is not Averaged Correctly?
I have some question on the power profiler for STM32WN on STM32Cube MX.I found that we can add BLE configuration on the left side of the tools, and it automatically calculate the average data of the BLE part.However the maximum advertisement interval...
Hello everyone, I have the flash memory AT25SF321B and I want to write and read it. As a µC I use an STM32WB55. I write some values but if i read it back i get only zeros. But i can read the manufacture id 1F 87 01. Hope you can help me.
