ZLG7289.rar - 程序名称：
数码管显示与键盘管理芯片ZLG7289的标准驱动程序（C51）
文件名：
ZLG7289.h ZLG7289.C
说明：
本程序已经调试通过
程序的可移植性很好，仅做少量修改就可以直接包含使用
程序占用资源少，仅使用4根必须I/O口线，不占用定时器等其它资源
所有全局性的标识符都以ZLG7289_开头，不必担心命名冲突问题
程序结构清晰，思路明确，结合ZLG7289的数据手册很容易理解
用法：
1、重新定义I/O接口
2、如果CPU的主频比较高，则要适当调整延时，详见ZLG7289_Delay()函数
3、在用户程序中包含本头文件
4、在main()函数的开始处添加初始化函数ZLG7289_Init()
5、以后在程序中可以直接使用ZLG7289的用户指令集
6、读取键盘扫描码使用函数ZLG7289_Key()，查询方式、中断方式皆可

DMA.rar - This example provides a description of how to use a DMA channel to transfer a
word data buffer from memory (Flash) to memory (RAM).
The dedicated DMA channel is configured to transfer once a time a 32 word data buffer
stored as constant in the Flash memory to another buffer in the RAM memory.
The received data are stored in the DST_Buffer.
The DMA channel transfer complete interrupt is enabled to generate an interrupt at
the end of the buffer transfer. As soon as the transfer is completed an interrupt is
generated and in the DMA channel interrupt routine the transfer complete interrupt
pending bit is cleared.
The data counter is stored before and after the transfer to show that all data has been
transfered.
TransferStatus gives the data transfer status where it is PASSED if transmitted and
received data are the same otherwise it is FAILED ,2008-03-17 23:52:26,下载21次
CortexM3.rar - This example shows how to use CortexM3 Bit-Band access to perform atomic read-modify-write
and read operations on a varaible in SRAM.

CAN.rar - This example provides a description of how to set a communication with the bxCAN
in loopback mode:
- transmit and receive a standard data frame by polling at 100Kbit/S
- transmit and receive an extended data frame with interrupt at 500Kbit/S
- lit some LEDs depending of the program succeed or not,2008-03-17 23:50:23,下载4次
BKP.rar - This example shows how to write/read data to/from Backup data registers and
demonstrates the Tamper detection feature.
The associated software performs the following:
Configures the Tamper pin to be active on low level and enable Tamper interrupt.
Then all Backup data registers are programmed after that we check if the written data
are correct. If yes a led connected to PC.06 is turned on, otherwise a led connected
to PC.07 is turned on.
Once a low level is applied on PC.13 pin (ANTI_TAMP) the Backup data registers are
reset and the Tamper interrupt is generated. In the corresponding ISR we check if
the Backup data registers are cleared, if yes a led connected to PC.08 is turned
on otherwise a led connected to PC.09 is turned on.
In this example the system is clocked by the HSE(8MHz).,2008-03-17 23:47:02,下载4次
ADC.rar - This example describes how to use the ADC and DMA to transfer continuously
converted data from ADC to a data buffer.
The ADC is configured to converts continuously ADC channel14.
Each time an end of conversion occurs the DMA transfers, in circular mode, the
converted data from ADC1 DR register to the ADC_ConvertedValue variable.
The ADC1 clock is set to 14 MHz.,2008-03-17 23:43:32,下载22次
