### WIFI
|
||||
|
||||
The default connected WIFI SSID is `无线DAP` , password `12345678`
|
||||
|
||||
Support for specifying multiple possible WAP. It can be added here: [wifi_configuration.h](main/wifi_configuration.h)
|
||||
|
||||
You can also specify your IP in the above file (We recommend using the static address binding feature of the router).
|
||||
|
||||
|
||||
|
||||
|
||||
There is built-in ipv4 only mDNS server. You can access the device using `dap.local`.

This project was originally designed to run on Keil, but now you can also perform firmware flash on OpenOCD.

Note that if you want to use a 40MHz SPI acceleration, you need to specify the speed after the target device is connected, otherwise it will fail with the beginning.

# Run before approaching the flash command

Winusb is now available, but it is very slow.

2020.2.4

|

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.
|
||||
|
||||
2020.1.31
|
||||
|
||||
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

这个项目最初是为在Keil上运行而设计的，但现在你也可以在OpenOCD上通过它来烧录程序。
|
||||
注意，如果你想使用40MHz的SPI加速器，你需要在连接目标设备后指定速度，否则会在开始时失败。
|
||||
|
||||
```bash
|
||||
# 在使用flash指令前需要先运行：
|
||||
> adapter speed 10000
|
||||
|
||||
> halt
|
||||
> flash write_image [erase] [unlock] filename [offset] [type]
|
||||
```
|
||||
|
||||
> 现已支持 pyOCD
|
||||
> Keil的操作时序与OpenOCD的有些不同。例如，OpenOCD在读取 "IDCODE "寄存器之前缺少SWD线复位序列。
