STM32L552 - trying to set 3 GPIO Pins as inputs(w/ wo pull-downs) to be read before most initialization, but some pins on the board are always HIGH?

2020-06-23
I'm trying to use 3 GPIO Pins as a 3-bit ID essentially. Depending on the values read, the uC will configure itself in an appropriate way (1 bin fits all tools essentially). The problem I'm having is that with the eval board the pins are pretty close...

Can I implement an emulated uart on an stm32l152 chip following this AP for the F4 series?

ref: https://www.st.com/resource/en/application_note/dm00110292-implementing-an-emulated-uart-on-stm32f4-microcontrollers-stmicroelectronics.pdfDue to pin restrictions, I've forced to send data on two GPIO pins not wired to any uart on the 152. I've ...

STM32L552-EV, attempting to IAP program the flash through UART connection, however always fails to send the bin file through Y-modem protocol.

I've been using the example AN4657 and following it to a T. I'm using the example project library files form the STM32L476G IAP_Main and modified them where necessary to work with the 552.I can successfully connect to TeraTerm via usart3 connection a...
