Hello,
TheĀ Renesas RA4M2 microcontrollerĀ has built-in USB functionality and comes with a USB driver library that can be used to developĀ USBĀ applications without an RTOS. Here are the general steps to use the RA4M2 USB drivers without an RTOS:
- Download and install the Renesas e2 studioĀ IDEĀ and the RA4M2 USB driver library.
- Create a new project in e2 studio for your RA4M2 microcontroller.
- Include the necessary USB driver library headers in your project.
- Configure the USB module on your RA4M2 microcontroller by setting the appropriate registers.
- Call the USB driver initialization function to initialize the USB module.
- Implement your USB application code, such as handling USB requests and transferring data to and from the USB device.
- Build your project and download the firmware to your RA4M2 microcontroller.
- Connect your RA4M2 microcontroller to a USB host device and test your application.
Thank You

Hello,
Connected to the internal CAN bus and loop back the messages received on node 2 to node 3 without any further processing by the CPU.
To accomplish this, you can configure both nodes to operate in normal mode and enable loopback mode for node 2 using the LBP bit in the NPCR register. The LBP bit sets the loopback mode for the node, allowing it to receive its own transmitted messages.
Here are the steps you can follow:
You can also use interrupts to receive messages on the nodes. You can enable interrupts for receive and transmit events and write interrupt service routines (ISRs) to handle the events. When a message is received, the corresponding receive interrupt will be triggered, and the data can be read from the received message object.
Kind Regards,
Alex Thomas
