+# Flipper Zero as CMSIS DAP/DAP Link
+Flipper Zero as a [Free-DAP](https://github.com/ataradov/free-dap) based SWD\JTAG debugger. Free-DAP is a free and open source firmware implementation of the [CMSIS-DAP](https://www.keil.com/pack/doc/CMSIS_Dev/DAP/html/index.html) debugger.
+
+## Protocols
+SWD, JTAG , CMSIS-DAP v1 (18 KiB/s), CMSIS-DAP v2 (46 KiB/s), VCP (USB-UART).
+
+WinUSB for driverless installation for Windows 8 and above.
+
+## Usage
+
+### VSCode + Cortex-Debug
+  Set `"device": "cmsis-dap"`

+},
+  ```
+</details>
+
+### OpenOCD
+Use `interface/cmsis-dap.cfg`. You will need OpenOCD v0.11.0.
+
+Additional commands: 
+* `cmsis_dap_backend hid` for CMSIS-DAP v1 protocol.
+* `cmsis_dap_backend usb_bulk` for CMSIS-DAP v2 protocol.
+* `cmsis_dap_serial DAP_Oyevoxo` use DAP-Link running on Flipper named `Oyevoxo`.
+* `cmsis-dap cmd 81` - reboot connected DAP-Link.

+  ```
+</details>
+
+### PlatformIO
+Use `debug_tool = cmsis-dap` and `upload_protocol = cmsis-dap`. [Documentation](https://docs.platformio.org/en/latest/plus/debug-tools/cmsis-dap.html#debugging-tool-cmsis-dap). Remember that Windows 8 and above do not require drivers.
