Modification of Mbed-dev library for LQFP48 package microcontrollers: STM32F103C8 (STM32F103C8T6) and STM32F103CB (STM32F103CBT6) (Bluepill boards, Maple mini etc. )

Fork of mbed-dev by mbed official

Warning!

This library is unable to work due to huge changes in the mbed toolchain. Do not use with mbed online!

Modification of Mbed-dev library for LQFP48 package microcontrollers: STM32F103C8 (STM32F103C8T6) and STM32F103CB (STM32F103CBT6) (Bluepill boards, Maple mini etc. )

Last commit 27 Apr 2017 by Nothing Special




Library for STM32F103C8 (Bluepill boards etc.).
Use this instead of mbed library.
This library allows the size of the code in the FLASH up to 128kB. Therefore, code also runs on microcontrollers STM32F103CB (eg. Maple mini).
But in the case of STM32F103C8, check the size of the resulting code would not exceed 64kB.

To compile a program with this library, use NUCLEO-F103RB as the target name. !

Changes:

  • Corrected initialization of the HSE clock (mbed bug), allowing the use of on-board xtal (8MHz).(1)
  • Additionally, it also set USB clock (48Mhz).(2)
  • Definitions of pins and peripherals adjusted to LQFP48 case.
  • Board led LED1 is now PC_13 (3)
  • USER_BUTTON is now PC_14 (4)

notes
(1) - In case 8MHz xtal on board, CPU frequency is 72MHz. Without xtal is 64MHz.
(2) - Using the USB interface is only possible if STM32 is clocking by on-board 8MHz xtal or external clock signal 8MHz on the OSC_IN pin.
(3) - On Bluepill board led operation is reversed, i.e. 0 - led on, 1 - led off.
(4) - Bluepill board has no real user button

bogdanm 0:9b334a45a8ff 37 * To generate a fatal run-time error, you can use the mbed error() function.

bogdanm 0:9b334a45a8ff 39 * @code
bogdanm 0:9b334a45a8ff 40 * error("That shouldn't have happened!");

bogdanm 0:9b334a45a8ff 43 * If the mbed running the program executes this function, it will print the
bogdanm 0:9b334a45a8ff 44 * message via the USB serial port, and then die with the blue lights of death!
bogdanm 0:9b334a45a8ff 45 *
bogdanm 0:9b334a45a8ff 46 * The message can use printf-style formatting, so you can report variables in the
bogdanm 0:9b334a45a8ff 47 * message too. For example, you could use this to check a run-time condition:
bogdanm 0:9b334a45a8ff 48 *
bogdanm 0:9b334a45a8ff 49 * @code
bogdanm 0:9b334a45a8ff 50 * if(x >= 5) {
bogdanm 0:9b334a45a8ff 51 * error("expected x to be less than 5, but got %d", x);
