I am currently using an STM32L452 MCU that operates using a custom bootloader and firmware package for operation. I have leveraged the bootloader on other projects before, so I knew (or at least thought i knew) it was solid. I'm learning that when i ...

Hi,I am currently trying to switch my code base from the RB version of the L010 family to the K4 version. I am doing this because the dev board I prototyped on was for the RB variant. I am building with arm (Keil).I am running into some issues in thi...

I currently am working with a stm32L010K4 mcu, but i have a startup script for stm32l010xB (startup_stm32l010xb.s). Where can I find a startup script for the stm32L010K4 mcu -- I'm guessing the name is startup_stm32l010x4.s ?

Hi--I/m pretty stumped. I am trying to implement a odd parity configuration for USART1 in an stm32L452RE micro. I've confirmed without parity the usart behaves as expected at the needed baud. When i introduce parity into the code and sniff the data o...

Hi. I'm operating an stm32l452 MCU which enters and exits shutdown mode frequently, and am using the internal RTC of the chip to keep track of time as the days progress. I have noticed that over continued use (with frequent exits/entrances to shutdow...

Yeah, so i figured out my issue -- i was inspecting memory/registers as i completed my erase prior to write, and noticed that my memory erased was a few pages off.Digging into this more, i learned this offset was due to my utilization of the uint32_t...

I'm stupid and paired down folders a bit ago. Forgot i did that and there is helpful items there...Thank you for the assistance!

for whatever reason my code didnt paste, but the response is spot on. good to go, thank you!

Yes, i am using the LSE clock source (that is the only one which can operate the RTC in shutdown). I'll check the capacitance to be sure thats correct.VDD is powered by 1.8V, which stays on during shutdown mode. It powers the MCU in which powers the ...

I have actually looked at that post. The thing that didnt make sense to me is if HAL_RTC_Init() is not called after each exit from shutdown mode on my chip, time cannot be successfully retrieved (HAL function errors out). I assume that the reason the...
