Have you ever used an embedded real-time OS (aka RTOS)?
I didn’t find the need for an RTOS because I have been developing program on the BLDC motors control and sending sensor data output serially.
However, with the recent trend of IoT, network connectivity has become part of the requirement. It is not realistic to implement the communication protocol such as SSL in bare metal and inevitably, I am being forced to use RTOS. 
Nowadays, we can easily get RTOS from major cloud venders for embedded IoT device for free. 
Though download of RTOS is easy, it seems quite tough to import it into the development environment and port it into the MCU.
Therefore, we have implemented the function in Renesas IDE e² studio, which realizes a RTOS project only by a few clicks.

Let’ get it running!
It needs only 4 steps.

  1. Start by launching e² studio.
  2. Select File → New project → ‘Renesas C/C++ Project’ → ‘Renesas RX’→’Renesas CC-RX C/C++ Executable Project’.
  3. Enter the project name.
  4. Start the project by selecting the RTOS type/board used/MCU. 

** It also supports AzureRTOS from Apr. 2021.

Operation is completed using e² studio. Isn’t it simple?

This function enables quick start of the RTOS program development in the environment you want.
In addition, e² studio ver.2021-07 and later supports the code generation function with smart configurator, which allows peripheral functions setting based on GUI. Please stay tune!
For other information, application note on ‘OTA firmware update’ using AWS and sensor information visualization (English version will be released in July 2021) are also available.  Please use them.
We recommend the use of evaluation board “RX65N Cloud Kit”, which has 3 types of sensors onboard, that can be connected to the cloud via Wi-Fi.
You can also use the setup guide video to helps you evaluate the connection to the cloud almost immediately.
