STM32Gxx add

[dlprfid]

Hi! Can you help add STM32Gxx targets to library? Or send manual step-by-step for add it. Thank you

Hi!

Now library has partial support for G0 (some features, such as EXTI does not works). Which series is your target?

In general, for add port you should implement series-specific methods for classes

[dlprfid]

Custom target, base on stm32g431.

Custom target, base on stm32g431.

You can open Reference Manual for G431and nearest analog already presented in framework (I think it will be F4XX). Duplicate this target folder and rename it with g4.

Next, compare features from RM, register names and CMSIS content and edit corresponding lines.

Usually it's simplest way to add new target if it not too different from "classic" ST MCUs.

You can ask me a questions in telegram.

Thank you! It's work )) Another one question. Can you write me method add FreeRTOS in project? Thank for your replay.

Hm, FreeRTOS and Zhele are independent. You can configure clocks with Zhele.

It's CMakeLists sample from some my project wich combines FreeRTOS ans my lib.

# Add zhele

FetchContent_Declare(Zhele
    zhele

# Add FreeRTOS

UPD: but I can recommend you more lighweight RTOS, such as scmRTOS.

[dlprfid]

Maybe you are right. Can you show me changes in make file if i make RTOS such as scmRTOS?

From another sample project (scm does not has CMake support out the box, just clone and copy it):

cmake_minimum_required(VERSION 3.16)
set(CMAKE_TOOLCHAIN_FILE ${CMAKE_CURRENT_SOURCE_DIR}/cmake/stm32_gcc.cmake)
set (CMAKE_CXX_STANDARD 20)

project(expander_scm CXX C ASM)

stm32_fetch_cmsis(F0)

find_package(CMSIS COMPONENTS STM32F0 REQUIRED)

# Add zhele
include(FetchContent)
FetchContent_Declare(Zhele
    GIT_REPOSITORY https://github.com/azhel12/Zhele.git

# Initialize and add BuguRTOS

target_link_libraries(expander_scm zhele::zhele CMSIS::STM32::F030x6 scm_core STM32::NoSys STM32::Nano)

[dlprfid]

Thx! I will try now

[dlprfid]

Sorry, scmRTOS folder put in src folder in project or in project's folder?

[dlprfid]

Can you show me this your file? scmRTOS.cmake

[azhel12]

[dlprfid]

Don't open (

[dlprfid]

Thx! All is ok.
