电子纸模组S3011CF1的单片机驱动程序源代码，GPIO模拟I2C接口。S3011CF1是EINK公司推出的一款断码式电子纸显示屏，具有3个8段数字和GB与百分比图形。

HART协议由Rosemount公司开发且已向每个使用者开放HART协议采用标准的Bell 202频移键控信号以1200波特通信以低电平加载于4mA~20mA模拟信号上，由于载波信号的平均值为零所以它对模拟信号没有影响。-HART agreement develops by Rosemount Corporation also opened the HART agreement to each user to use the standard the Bell 202 frequency-shift keying signal increase by 1,200 bauds correspondences by the low level on the 4mA~20mA simulated signal, because intelligence signal mean value for zero therefore it has not affected to the simulated signal.
