基本信息

项目使用ESP32-S2主控驱动GC9A01 240x120 LCD液晶屏,通过SMBus连接BQ40Zxx电量计,读取并显示实时电压、电流等信息

基于ESP-IDF框架,液晶屏幕使用lvgllvgl_esp32_drivers驱动

目前仅在BQ40Z80电量计芯片上进行测试,理论上BQ40Z50芯片的大部分SBS Command与其均相同,也能支持

BQ40Z80的硬件设计可参考acha666/BQ40Z80

进度

  • 能编译
  • 能亮
  • 第一个GUI页面(电压、电流、剩余电量)
  • 第二个GUI页面(每节电芯的电压、寄存器信息)
  • 按钮交互
  • 配套硬件模块

致谢

感谢Linho为美工苦手提供的GUI设计
