常见的有30针脚(Pin)和36pin,还有ESP32CAM这种异形规格的 这使得与屏幕连接(SPI协议)产生不少坑,本文将会分析一下自己过程中踩过的坑 本文主要使用DOIT ESP32 DEVKIT V1(后文略称doit),通过TFT_eSPI(后文略称TFT)来驱动屏幕ST7789 Adafruit ST7789/ST7735也使用过,只用于和ESP8266连接(doit失败了) 并且TFT...
I'm using the two GND connections for different things, anyway, 5V side GND for some LEDS, the 3.3V side for I2C and an IR movement sensor, in my last project. 3.3V entirely in my current one, which is interesting, as WS8212 LEDs are not supposed to work on 3.3V, but they do,...
ESP32 is already integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters, and power management module. The entire solution takes up the least amount of printed circuit board area.This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low pow...
