Resolved! STM32L496QGI3 Vbat pin connection
Hi, Can the VBAT pin on this part be left floating? I currently have the pin disconnected. Or should it be tied to VDD or GND in order for the part to function properly? Thanks,
Terminal flickering when sending characters through UART
Hello,I am attempting to create a guitar hero-style game using the B-L4S5I-IOT1A board. I have an array representing the notes to play and wish to update the display every 125ms with a new gameplay frame (a given frame has the next 10 notes the user ...
STM32 software library for implementing a sensor hub
Hi, I want to implement a sensor hub that can connect to multiple (e.g. 8 ) sensors (from the same type), collect data from them, aggregates the data into a single message and sends it out. The board will be custom, if necessary, and based on e.g...
STM32H563 LSE does not always start
I am using an stm32h563 nucleo 144 board, and I am frequently running into the issue that after a power cycle the LSE does not start.This is the relevant part of my SystemClock_Config: LL_PWR_EnableBkUpAccess();while (LL_PWR_IsEnabledBkUpAccess () ==...
