--- 模块功能：lcddemo
-- @module lcd
-- @author Dozingfiretruck
-- @release 2021.01.25

-- LuaTools需要PROJECT和VERSION这两个信息
PROJECT = "lcddemo"
VERSION = "1.0.0"

log.info("main", PROJECT, VERSION)

-- sys库是标配
_G.sys = require("sys")

--添加硬狗防止程序卡死
if wdt then
    wdt.init(9000)--初始化watchdog设置为9s
    sys.timerLoopStart(wdt.feed, 3000)--3s喂一次狗
end

-- 按实际情况修改, spi的id, cs脚, 波特率, 都要按实际情况改
spi_lcd = spi.deviceSetup(5,pin.PC14,0,0,8,48*1000*1000,spi.MSB,1,1)

--[[ 下面为custom方式示例,自己传入lcd指令来实现驱动,示例以st7735s做展示 ]]
-- [[ 注意修改下面的pin_xx对应的gpio信息, 数值与pin.XXX 均可]]
-- initcmd的含义, 分3种指令, 每个指令都是int32, 前2个字节是命令, 后2个字节是值
-- 0001 delay  延时, 例如 00010002 , 延时2ms
-- 0002 cmd    发命令, 例如 0002004, dc设置为CMD模式, SPI发送 0x04
-- 0003 data   发数据, 例如 0003004, dc设置为DATA模式, SPI发送 0x04
