 SiFive HiFive1 Rev B ESP32 - WiFi connection demo
+
+A small demo application that enables the following on a SiFive HiFive1 Rev B RISC-V board:
+* UART: 115200 bps
+* SPI: 80 KHz
+* CPU: 320 MHz
+* WiFi in Station mode (client)
+
+## Requirements
+* [IAR Embedded Workbench for RISC-V](https://www.iar.com/riscv)
+* or [SiFive Freedom Studio](https://www.sifive.com/boards)
+
+## Build instructions
+Create an empty Freedom E SDK Software project for:
+* Target: `sifive-hifive1-revb`
+* Example program: `empty`
+
+Copy the source files from this repository into the `src` folder and build.  
+Copy the generated `empty.hex` into the HiFive USB drive.
+
+## Usage 
+Connect to the UART used for the FE310-G002/HiFive1 console, using for example [Tera Term](https://ttssh2.osdn.jp/index.html.en).  
+The output should look like this (press the Reset button on the board if it does not work):
+```
+Bench Clock Reset Complete
+
+ATE0-->ATE0
+OK
+AT+BLEINIT=0-->OK
+AT+CWMODE=0-->OK

+After the WiFi connection is made, press ENTER to disable it.  
+After that, you can enter any AT commands from [ESP32 AT Instruction Set and Examples](https://www.espressif.com/sites/default/files/documentation/esp32_at_instruction_set_and_examples_en.pdf)
