SMT32 Programmer RTC Stop Reading Data Hang or Freeze
How to fix problems with SMT32 Programmer RTC stop reading data
SMT32 Programmer RTC - This tutorial was created to solve the problems I've experienced. This is my second attempt when testing the STM32F103C8T6 arm STM32 or Blue Pill board.
I am interested in this STM32 because it has an internal RTC, so we don't
need an RTC module in our project anymore. when this happens, the circuit
After I installed the library and successfully programed Blink to STM32, I
tried to reprogram the example given by stm32arduino for reading RTC data
using ST Link 2.
From this experiment, I got a problem with reading data from RTC. Every time data reading is done, suddenly STM32 no longer provides RTC data through Serial Monitor.
I get this problem in days. I attach a serial photo monitor of this problem as shown below:
How to Fix STM32 Internal RTC Not Working
Please do not use PC14 and PC15 pins to connect with other devices, if you are also using Internal RTC. This will disturb the 32,768 Hz oscillator, so the RTC doesn't work properly.
