Hi,

I have a RA4M2 eval kit and am working on a product for that MCU. From what I can see the USB example code provided for this MCU uses FreeRTOS, with the USB send and admit running in its own thread.

I believe my product doesn’t need an RTOS. Would it be possible to use the RA4M2 USB drivers without any RTOS, with the send and receive running in a circle in the main thread? Would there be any example code for this?

Thanks,

Vikas

    Hello,

    The Renesas RA4M2 microcontroller has built-in USB functionality and comes with a USB driver library that can be used to develop USB applications without an RTOS. Here are the general steps to use the RA4M2 USB drivers without an RTOS:

    • Download and install the Renesas e2 studio IDE 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
