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
• or SiFive Freedom Studio

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.

Usage

Copy the generated hex file into the HiFive USB drive.
(Or, simply use the pre-built hex file hifive1_revb_wifi.zip).

Connect to the UART used for the FE310-G002/HiFive1 console, using for example Tera Term.
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.
For example, this will return the IP address:

ATE0
AT+CWMODE=1
AT+CWJAP="ssid","pwd"
AT+CIFSR
