RA-Renesas R7 small desk lamp

1. Use Renesas R7FA2E1A72DFL to realize touch button control of LED light switch and brightness adjustment.

2. Use the H-bridge drive circuit as an LED driver. You can also drive the motor for fun if you don’t need it in the future.

3. There are some circuits that are not used and are used to verify other things, such as Q1, Q2, and operational amplifiers in the schematic diagram. They can be ignored in this project.

1. I can’t handle touch without an emulator, so I changed it to buttons.

2. There is a small problem with the driving circuit. I changed it to using the mos tube alone to drive the LED light.

3. I forgot to adjust the brightness, and finally connected an external one (the touch is useless anyway and the buttons are connected externally)

4. I feel like I might as well make a development board for fun.

5. Some functions feel too late, such as different ratio dimming of two colors of light. Let’s look at it later.

6. RA_td01 in the attachment is code (actually the serial port and external interrupt are not used, just for debugging). The oled code in some E1 development board routines has been modified to make it easier to use when displaying 6*8 small characters.
