(在两个中)识别最大模拟输入通道
- (在两个中)识别最大模拟输入通道 利用0809采集两路模拟电压,将电压值最大的通道号显示在LED显示器上。(硬件电路参见AD_CH2_1.DSN)。((in two) identifying the maximum analog input channel Using 0809 to collect two analog voltage, the voltage value of the largest channel number is displayed on the LED displ
PWM波发生器
- 在硬件电路PWM.DSN中实现P1.7输出PWM波。周期T=100ms,初始占空比(T1/T)为50%,按键KEY1每次增加占空比10%(直到90%),KEY2每次减小占空比10%(直到10%)。(In hardware circuit PWM.DSN, P1.7 output PWM wave is realized. The cycle T=100ms, the initial duty cycle (T1/T) is 50%, the key KEY1 increases by 10% e
3X3键盘扫描
- 利用8155的PB、PC口实现3X3键盘扫描(硬件电路参见3X3KEY_8155.DSN)。当1~8号键独立按下时,连接在PA口对应的LEDx点亮(即1号键按下时LDE1亮,2号键按下时LDE2亮),当9号键按下时,所有LED点亮,当没有键按下时,所有LED熄灭。(3X3 keyboard scanning with 8155 PB and PC ports (hardware circuit, see 3X3KEY_8155.DSN). When the 1~8 button is press
50赫兹同步锯齿波发生器
- 利用0832同步输出两个频率为50赫兹的锯齿波(硬件电路参见DA_BUF2_1.DSN)。(Using 0832 simultaneous outputs, two sawtooth waves with frequencies of 50 Hz (hardware circuit refer to DA_BUF2_1.DSN) are used.)
编码显示器
- 利用8255扩展并行端口(硬件电路参见CodeDisplay_8255.DSN)。当KEY按下时,利用8255的PC口输入二进制值编码(6位),将该值转换成十进制后显示在2位7段LED显示器上。(Using 8255 to extend parallel ports (see CodeDisplay_8255.DSN for hardware circuits). When the KEY is pressed, the binary value encoding (6 bits) is ent
