3280Led点阵时钟，08接口

基于STM32的PDA源代码，此PDA界面类似Windows98，功能请自测，完美支持原子迷你板，注意，在使用此工程文件夹之前，请把板子上的W25Q16替换成W25Q64，因为此PDA的一切图标，字库都存放在这个芯片里，板子标配的2M不够用，我替换成8M的。用户需要注意一下， 在使用之前先配置一下工程包，如果你的原子板是2MFlash芯片的，请打开theme.h文件，把ICO_TO_SD更改为1，重新编译后下载，如果你的Flash是8M的W25Q64，就可以直接下载了，ICO_TO_SD这个功能是配置你的图标存放位置的，1为SD卡，0为Flash的那个芯片，也就是W25Q64，如果你的这个芯片是2M，而又忘记把ICO_TO_SD修改为1后下载的话，会导致死机，死在图片解码里。

Modbus RTU Slave project based on Microchip PIC 16F87X processor and 24LC128 CMOS Serial EEPROM with I2C interface. PIC Modbus RTU slave supports write and read (3 and 16) functions. The data is stored and read from EEPROM via the I2C bus. You can write/read up to 8000 registers. In a single frame can be read/write 32 registers .
