I want to use PicSimLab Blue Pill STM32 on Keil Studio Cloud, How to set the build target and connect the device?
Mbed does not support Blue Pill directly, but it could be used as a custom target.
You can look to this
- Bluepill board support for Mbed OS 6 - Custom and community boards - Arm Mbed OS support forum
- ARMmbed/stm32customtargets: Enable the support of your custom boards in mbed-os 6 (github.com)
