UCDOS16x16汉字字库的二进制字模文件-UCDOS16x16 汉字字库的???8 制字模文?

单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-smallest SCM system, two LED digital serial output from the pipe then two 164-driven, Lout, Rout for about channel output, SET, ALT0, ALT1 to three keys, but also his own in the beginning I/O definition you want to change the I/O port; If using crystal 12M 89C51 can carry only about 14 songs, can be loaded with 89C52 Near 40

这是我自己写的18B20驱动程序，不需修改，做的温度计精度很高。大家在做温度采集明无需修改，只需添加上既可使用。-This is what I wrote it myself, 18B20 driver without modification to do high precision thermometer. We do no need to modify the temperature acquisition out, simply add the can use.

arm开发板nfs启动脚本，通过nfs启动单板，使用主机文件系统资源-arm development board nfs startup script, through nfs start veneer, use the host file system resources

八路电压表C程序 使用AT89C52单片机，12MHZ晶振，P0口读入AD值，P2口作AD控制，用共阳LED数码管 P1口输出段码，P3口扫描，最高位指示通道（0-7）。-Eight-way voltage meter C program using AT89C52 single-chip, 12MHZ crystal, P0 I read into the AD value, P2 I make AD control, with a total of P1 Yang LED digital tube output above code, P3 port scan, the maximum channel bit instructions (0-7).

一个已经作成过成品的MON51的电路原理及PCB 图。-make an already finished off the MON51 Principle and the PCB circuit map.

芯片使用51+ch375,程序用180行C代码就能够读取FAT16文件系统U盘的根目录,可以看到根目录下的文件名,并可显示首文件内容-chips use 51 ch375, procedures using 180 OK C code can read FAT16 file system drives the root directory, we can see the root directory under the file name, would show the contents of the documents first
