-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)
+In order to use SPI acceleration, you need to physically connect `SWDIO(GPIO12)` to `SWDIO_MOSI(GPIO13)`.
+
+Here, we give a simple example for reference:
+
+![sch](https://user-images.githubusercontent.com/17078589/107851862-f9589e80-6e47-11eb-9eca-e80760822a6a.png)
+
+Alternatively, you can connect directly with wires as we gave at the beginning, without additional circuits.
+
+
+> If you need to modify the LED or JTAG pins, please refer to the instructions in [DAP_config.h](components/DAP/config/DAP_config.h) to modify them carefully.

+## Speed Strategy
+
+The maximum rate of esp8266 pure IO is about 2MHz.
+When you select max clock, we will take the following actions:
+
+- `clock < 2Mhz` : Similar to the clock speed you choose.
+- `2MHz <= clock < 10MHz` : Use the fastest pure IO speed.
+- `clock >= 10MHz` : SPI acceleration using 40MHz clock.
+
+> Note that the most significant speed constraint of this project is still the TCP connection speed.
