RUSA_TEST

1. For the first time, Lichuang EDA was used for circuit board design and 3D shell design.

2. Use Renesas MCU for development for the first time

3. Use Renesas FSP combined with MDK for code development for the first time.

4. The details of the project are as follows

     4.1. Using Renesas’ R7FA2E1A72DFL as the processor

     4.2. USB external power supply access

     4.3. Use the GPIO of the processor for buzzer control

     4.4. Use the PWM of the processor to control the RGB light strips

     4.5. Use the IIC interface to connect to the infrared sensor DITS Sensor 1901 to measure human body temperature.

     4.6. Use processor touch buttons for function settings.

     4.7. SWD’s JLINK debugging interface.

5. The software process is as follows:

      5.1. Power-on initialization

      5.2. The buzzer beeps three times.

      5.3. The brightness of the RGB light strip displays in a cycle from low to high.

      5.4. Sensing human body temperature

      5.5. The buzzer will sound and the light strip will display according to the temperature value.

6. Problems and improvements

      At the beginning of the design, it was not enough to consider all aspects, including the function of the equipment, the location of the components, etc.

       Secondly, the data research is not enough, including the use of software and the upgrade of JLINK, which wastes a lot of time.

       Third, the overall feeling is that there is less information online about Renesas processors. Development is more difficult, especially in-depth development, which requires more time.

       Finally, with a learning attitude and using my spare time, I learned a lot of knowledge, which is worth it!
