Overview
Description
The RA4E2 Fast Prototyping Board comes equipped with an R7FA4E2B93CFM microcontroller and is an evaluation board specialized for prototype development for a variety of applications. It has a built-in SEGGER J-Link™ emulator circuit so you can write/debug programs without additional tools. In addition, with Arduino Uno and Pmod™ interfaces included standard and through-hole access to all pins of the microcontroller, and so on, it has high expandability.
Sample software is available to demonstrate the functionality of the RA4E2 MCU and for connecting between the RA4E2 Fast Prototyping Board and various wireless modules or various sensor modules.
Please use Bluetooth®, LoRa®, and Wi-Fi according to the radio regulations of each country during use.

- RA4E2 how to start ADC group B and its interrupt?
Hi, I have two timers g_timer0 and g_timer1 running at 100kHz and 10kHz respectively. I can see their trough interrupts in SW ISR routine. I have setup the ADC in group scanning mode with group A to be started by g_timer0 UDF and group B by g ...
Oct 4, 2024 - How to make FSP5.5.0 generate correct vector_data.c and vector_data.h when GTP timer interrupts are enabled?
Hi, I have a FPB_RA4E2 board. I have found out how to start the blinky project and add the GPT PWM. They are working. However, I have hard time understanding how to add GPT timer interrupts as the FSP interrupts tab "New User Event" button does not give me ...
