DAPLINK

Introduction: DAP emulator is an open source emulator officially launched by ARM. It is copyright-free and freely produced. Made with STM32F103C8T6, input USB-C interface, output double row pins and 1.0 pitch 6P port, with virtual serial port function, support Crotex core chip, support SWD download method, no need to install driver, maximum download speed: 10Mhz10M

1. Project introduction : This project is designed to be a DAPlink emulator. The DAP emulator is an open source emulator officially launched by ARM. It is copyright-free and freely produced. It does not require a driver and can be used just by plugging it in. It supports all Cortex core microcontrollers, regardless of the manufacturer.

2. Project description

1. This emulator takes the STM32F103C8T6 chip as the core and can be used for downloading and simulation debugging of Cortex-M0/M1/M2/M3/M4/M7 and other core devices. It has a virtual serial port function.

2. Program download supports SWD mode, and the maximum speed can reach 10M.

3. The computer side uses USB TYPE-C interface, and the microcontroller side uses 2.54mm double row pins or 1.0mm 6P terminals, which can be freely selected according to actual needs.

4. The onboard LDO-SC662K can supply external 3.3V power supply, and the current is recommended to be less than 100mA.

5. The module interface definition is as shown in the figure below.

6. The firmware and software source code are shown in the appendix. The software project can be compiled using KEIL MDK5. The software download link is https://www2.keil.com/mdk5.
