## Hardware

Platform ST STM32: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Microcontroller | STM32F103ZET6
Frequency | 72MHz
Flash | 512KB
RAM | 64KB
Vendor | Generic

## Configuration

Please use `genericSTM32F103ZE` ID for board option in “platformio.ini” (Project Configuration File):

    [env:genericSTM32F103ZE]
    platform = ststm32
    board = genericSTM32F103ZE

You can override default STM32F103ZE (64k RAM. 512k Flash) settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest genericSTM32F103ZE.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:genericSTM32F103ZE]
    platform = ststm32
    board = genericSTM32F103ZE

    ; change microcontroller
    board_build.mcu = stm32f103zet6

    ; change MCU frequency
    board_build.f_cpu = 72000000L

## Uploading

STM32F103ZE (64k RAM. 512k Flash) supports the next uploading protocols:

- `blackmagic`

- `dfu`

- `jlink`

- `serial`

- `stlink`

Default protocol is `stlink`

You can change upload protocol using upload_protocol option:

    [env:genericSTM32F103ZE]
    platform = ststm32
    board = genericSTM32F103ZE

    upload_protocol = stlink

## Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

STM32F103ZE (64k RAM. 512k Flash) does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools | On-board | Default

## Frameworks

Name | Description
--- | ---
Arduino | Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.

CMSIS

The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices.

libOpenCM3 | The libOpenCM3 framework aims to create a free/libre/open-source firmware library for various ARM Cortex-M0(+)/M3/M4 microcontrollers, including ST STM32, Ti Tiva and Stellaris, NXP LPC 11xx, 13xx, 15xx, 17xx parts, Atmel SAM3, Energy Micro EFM32 and others.
STM32Cube | STM32Cube embedded software libraries, including: The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls; The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency.
