STM32F7XX library for MMDVM project
|
|
|
|
This is the STM32F7XX_Lib directory structure with just the needed code for MMDVM.
|
|
Copy this STM32F7XX_Lib directory inside the MMDVM source code project. You have to
|
|
conserve the STM32F7XX_Lib folder name: MMDVM/STM32F7XX_Lib
|
|
|
|
The source of CMSIS library and some include files is from STM32Cube_FW_F7_V1.7.0:

In order to run the MMDVM firmware correctly, there are the following modifications
|
|
already done in this package:
|
|
|
|
1) STM32F7XX_Lib/Device/startup/startup_stm32f7xx.c :
|
|
- Added C++ global constructors support
|
|
- Changed initial stack pointer
|
|
- Changed support for STM32F767
|
|
|
|
2) STM32F7XX_Lib/Device/system_stm32f7xx.c :
|
|
- Changed PLL_M definition (support "integer" only crystal frequencies: 8, 12, 16 MHz, etc)
|
|
- Added functions: SetSysClock(), MPU_Config(), CPU_CACHE_Enable() from examples in https://gitlab.com/caesar-lab/stm32f7-legacy-library
|
|
|
|
3) STM32F7XX_Lib/Device/stm32f7xx_hal_conf.h :
|
|
- Peripheral header file inclusions
