## Link your board
|
|
|
|
1. WIFI
|
|
|
|
The default connected WIFI SSID is `DAP` , password `12345678`
|
|
|
|
You can change `WIFI_SSID` and ` WIFI_PASS` in [wifi_configuration.h](main/wifi_configuration.h)
|
|
|
|
2. Debugger

You can modify these pin definitions in [DAP_config.h](components/DAP/config/DAP_config.h)
|
|
|
|
> Tips: Try to avoid using `GPIO0`(working mode switch) and `GPIO16`(RTC)
|
|
|
|
## Build
|
|
|
|
1. Get ESP8266 RTOS Software Development Kit
|
|
|
|
See: [ESP8266_RTOS_SDK](https://github.com/espressif/ESP8266_RTOS_SDK "ESP8266_RTOS_SDK")
|
|
|
|
2. Build & Flash
|
|
|
|
Build with ESP-IDF build system.
|
|
More information can be found at the following link: [Build System](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system.html "Build System")
|
|
|
|
The following example shows a possible way to build on Windows:
|
|
|
|
```bash
|
|
# Build
|
|
python ./idf.py build
|
|
# Flash
|
|
python ./idf.py -p /dev/ttyS5 flash
|
|
```
|
|
|
|
> We also provided sample firmware quick evaluation. See [Releases](https://github.com/windowsair/wireless-esp8266-dap/releases)
|
|
|
|
|
|
## Usage
|
|
|
|
1. Get USBIP project
|
|
|
|
- Windows: [usbip-windows](https://github.com/george-hopkins/usbip-windows "usbip-windows") . Or you can find it already built here: https://github.com/barbalion/usbip-win-client
|
|
- Linux: Distributed as part of the kernel
|
|
|
|
2. Start esp8266 and connect it to the device to be debugged
|
|
|
|
3. Connect it with usbip:
|
|
|
|
```bash
|
|
.\usbip.exe -D -a <your-esp8266-ip-address> 1-1
|
|
```
|
|
|
|
If all goes well, you should see your device connected.

## Develop

|
|
> Credits to:

In this repo you can find the complete implementation of the USB protocol stack including USB-HID, WCID, WinUSB. Although WinUSB-based mode currently does not work on USBIP :disappointed_relieved: . They are very easy and can help you quickly build your own DAP on other hardware platforms.
|
|
|
|
|
|
Currently using USB-HID for transmission is still slightly slower, If you have any ideas, welcome:

### Issue
|
|
|
|
2-4
|
|
|
|
Due to the limitation of USB-HID (I'm not sure if this is a problem with USBIP or Windows), now each URB packet can only reach 255 bytes (About 1MBps bandwidth), which has not reached the upper limit of ESP8266 transmission bandwidth.
|
|
|
|
I now have an idea to construct a Man-in-the-middle between the two to forward traffic, thereby increasing the bandwidth of each transmission.
|
|
|
|
1-31
|
|
|
|
At present, the adaptation to WCID, WinUSB, etc. has all been completed. However, when transmitting data on the endpoint, we received an error message from USBIP. This is most likely a problem with the USBIP project itself.
|
|
|
|
Due to the completeness of the USBIP protocol document, we have not yet understood its role in the Bulk transmission process, which may also lead to errors in subsequent processes.
|
|
|
|
We will continue to try to make it work on USB HID. Once the USBIP problem is solved, we will immediately transfer it to work on WinUSB
