There are two ways to use C++ with DUELink, hosted or Standalone.

Hosted​

With a hosted option, a PC & Laptop or Phone & Tablets can be used to run the C++ program to command DUELink modules through USB or UART Serial interfaces.

This is an example

//code

Standalone​

With this option, a DUELink module is executing a compiled C++ program developed by you. All modules utilize a STM32C071 microcontroller, which is supported by many IDEs, including free STM32CubeIDE. We however use ARM Keil MDK. This is a paid professional IDE but ST has already licensed it to make it available for free for any STM32 Cortex-M0 micro.

tip

These options use low-end versatile libraries. They are powerful but not user friendly! Arduino is a user-friendly alternative.

// example

Any DFU update tool can be used to load your compiled program onto a DUELink module. We recommend the STM32CubeProgrammer.

tip

99.9% of modules include SWD pins if you want to connect a debugger, such as ST-Link. SWCLK is found on the through hole "boot pads" or LDR button. SWDIO is found on a tiny SMT pad.
