LEB-4.3RGB_V2.0

Overview

Project Introduction

: 1. This screen expansion board is compatible with the 01_RTC_LCD_v1.0 motherboard; if you want to adapt to other motherboards, you can refer to this design concept.
2. V2.0 is compatible with the Yaoyuan Hongjia 4.3-inch RGB capacitive touchscreen (resolution: 800*480). This screen is cheaper than the screen compatible with V1.1, so you can save money when buying the screen if you are replicating it.
3. You can further improve the screen driver circuit according to the manual. In addition, you can configure the current resistor according to your desired screen brightness (the larger the resistance, the smaller the current, and the dimmer the screen; and vice versa); if you need more information, you can contact the manufacturer directly.
4. QQ group for communication: 26875961; feel free to join the group to discuss any questions!

[Help] What is the difference between P1DIR |= 0x01 and P1DIR |= BIT0+BIT4?
I saw that Hu Dake's book defines P1.0 as output using the above two methods, but the two values are different? 0x01 and BIT0+BIT4 (BIT0=0x0001, BIT4=0x0010)
