说明：  32位单片机HR8P506上运行FreeRTOS，HR8P506是一款Cortex-m0内核的国产单片机，支持2.5-5.5V的宽电压，36KB Flash和8KB SRAM能够满足绝大多数的应用开发。(32-bit MCU HR8P506 runs FreeRTOS. HR8P506 is a domestic MCU with cortex-m0 kernel, which supports a wide voltage of 2.5-5.5v, 36KB Flash and 8KB SRAM which can meet most application development.)

这个源码是利用STM32驱动COG128128，并让其显示常用ASCII码字库的例子。液晶使用的控制器是UC1617，STM32使用的是R8T6。由于UC1617每次发送一个字节数据是写入4个像素点，而不是普通的8个像素点，所以传统的液晶驱动无法匹配普通字库生成软件生成的字库，在这个例子当中，通过修改底层通讯驱动的方式来“曲线救国”，实现可以在UC1617驱动下的COG128128液晶屏幕上调用字库显示。(This source is the use STM32 drive COG128128, and let it display the ASCII character common examples. LCD controller using the UC1617, STM32 using R8T6. Since UC1617 each time you send a byte of data is written to four pixels, rather than ordinary 8 pixels, so the traditional LCD driver can not match the general character generation software to generate the font, in this example, by modifying the underlying communication driven approach to "Quxianjiuguo" and realize you can call on COG128128 character driven LCD display screen UC1617.)
