用 PWM +键盘控制 直流电机转动 SPCE061A 的处理器

在keil C51下的fm24c04a的c程序-in the process of c fm24c04a

采用直流电机测速单元模拟出租车速度，通过A/D转换进行速度采样，利用单片机的定时器/计数器定时和计数，用LED数码管或LCD显示总价和时间，并通过键盘进行单价设定及时间显示，键盘功能自行定义。-DC Motor Speed modules using simulation taxi speed, through the A/D conversion speed of sampling, the use of single-chip timer/counter timing and counting, with LED digital tube or LCD display the total price and time, and through keyboard Price settings and time display, keyboard function on its own definition.

以SPCE061A单片机为核心，通过DDS合成技术设计制作了一个步进值能任意调节的多功能信号源。该信号源在1KHz～10MHz范围能输出稳定可调的正弦波，并具有AM、FM、ASK和PSK等调制功能。信号输出部分采用低损耗电流反馈型宽带运放作电压放大，很好地解决了带宽和带负载能力的要求。系统带中文显示和键盘控制功能，操作简便，实现效果良好。-SPCE061A can preview and so on 片 Lennon为， Center Services Toru DDS magnetic rude summarized chirpy术instance, a few leftover制brazing stamp festival值vehicles Qin Kui 任 comment slander people cavity features信ulcers ulcers信Tai Tai 。 clams Now 1KHz `10MHz Kui Yu围HUAI embankment稳corner cavity strip Qin Shu Hao ，弦bleed at the nose of sweet seized AM) FM) ASK Core inflation PSK Tan制features 。信ulcers HUAI snapped embankment Qun Xu malaria tablets using delicious cream changchu destroyed sneeze型compliance turbulent changchu压brazing temperature side of bridge ， exhaust temperature submerged low-hua chiao suspect left Rui turbulent turbulent compliance pupa Xikui weak potato cavity lynx 求 。 department turbulent conduct anti中striped text显Rui-ying制satirical features captured ， ， Fuzeng brazing Canals Xi现invalid wife of mother

使用凌阳单片机，控制5088编码芯片编码并传输到8870解码芯片，得到所需数字信号。-Sunplus use single-chip, chip encoding control code 5088 and transmitted to the 8870 decoder chip, get the digital signal.

DESCRIPTION =========== This example project shows how to use the IAR Embedded Workbench for ARM to develop code for the Atmel AT91SAM9261 evaluation boards. It shows basic use of parallel I/O, timer and the interrupt controller. It starts by showing different patterns on the LED s separated by half second. COMPATIBILITY ============= The project is compatible with the AT91SAM9261-EK board.
