Description: 這是一個用PL2303轉接的JTAG ICE，雖說還是串行通訊，但是我認為的確是方便和小巧。驅動芯片我這裡的74HC245比較多，所以沒用244，其實是一樣的。Mega16L選用的是TQFP封裝。

Description: 彩屏使用 ILI9235 主控芯片
液晶插针J2使用了如下信号：
数据端：
AD0-AD7 或者 DB0-DB7
控制信号 ：
S-指令/数据
WR-写控制
CS-使能
RST-复位
没有使用RD （读控制）
主板上一个稳压芯片 LM1117-3.3 作用是把5V电压转换为3.3V
74hc245 用户电平转换
SD 部分使用4个数据线 使用SD卡的SPI模式
CS-使能
SCK-时钟输入
DOUT-数据输出
DIN-数据输入
-Use the ILI9235 master chip LCD color screen pin J2 signal as follows: data end: AD0-AD7 or DB0-DB7 control the signal: S-instruction/data the WR-write control CS-enable RST-reset did not use the RD (read control) on the motherboard voltage regulator chip LM1117-3.3 5V voltage conversion to convert 3.3V 74hc245 user level the SD section uses four data lines using the SD card SPI mode CS-enable SCK-clock input the DOUT-data output DIN-data input
