Overview

Introduction

The R7FA4 Plus development platform provides users with an economical, flexible and convenient way to realize more creative ideas. On the hardware, it features Renesas Electronics' powerful 32-bit microcontroller R7FA4M1AB3CFM, which has expanded memory, peripherals, and faster clocks, enabling it to easily handle complex projects.

Features

• Based on R7FA4M1AB3CFM, and is compatible with Arduino UNO R4 Minima.
• Utilizes Renesas Electronics' RA4M1 (Arm® Cortex®-M4) microcontroller, with a main frequency of 48MHz.
• Equipped with 256 kB Flash and 32 kB RAM, the expanded memory can easily handle complex projects.
• The R7FA4 Plus development board adds a 12-bit DAC, CAN bus and operational amplifiers, providing expanded functionality and flexibility for designs.
• Onboard 5V/3.3V headers for easy voltage switching, allowing the use of more expansion modules.
• Flexible power options, supporting USB-C power supply or external input power VIN (6V<=VIN<=24V).
• Onboard power indicator (PWR), USER LED, serial port receive indicator (RX) and transmit indicator (TX), making it easy to monitor the working status of the development board.
• Onboard ICSP interface, can be used as an SPI interface.
• Supports user soldering of corresponding interface insertion into the experimental board.

Arduino IDE Development

Install Arduino IDE

• The following development is based on Windows by default.

1. Open download page, and select the corresponding one to download according to your system and system bits.
   
   
2. Select "JUST DOWNLOAD" OR "CONTRIBUTE DOWNLOAD".
   
   
3. Just run to install and install all the defaults.

Install Board Package

• Please open "Board Manager" on the left, search "UNO R4 Minima" and install the latest version (or the version to be used):

Create Example

• The following example is about how to make LED blinks (File -> examples -> Blink under 01.Basics).
  

• Select the development board and COM port.

Search UNO R4, select Arduino UNO R4 Minima, and then click on "OK".

• Click ✓ in the menu bar to compile, and click → to burn the compiled program to the board.

Open Example

• Open the existing example, the operation is simpler, directly run the corresponding .ino demo, refer to the operation above, select the corresponding board and port, compile, download and burn.
  

Example Explanation

GPIO_TEST

This demo is for testing the GPIO0-13 output, in this demo, the GPIO0-13 is initialized as output mode and outputs the high level or low level in order. 

ADC_TEST

The Photosensitive demo obtains the value of the photosensitive resistor by reading the value of the pins A0-A5. If the value is greater than or equal to 730, the LED pin will be turned on and the relay pin will be switched on. Otherwise, the LED pin will be turned off and the relay pin will be switched off.

The Read_Analog_Input demo obtains the value of the analog pin of the raindrop sensor by reading the value of the pin A0. If the value is less than 500, the LED is on; otherwise, the LED is off.
