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

按键扫描 51单片机加8279
8279通过74LS 138译码器扩展4×4键盘、6位显示器。
由3-8译码器对SL0~SL2译出键扫描线,由另一3-8译码器译出显示器的位扫描线,并采用了编码扫描方式。
为了防止出现重键现象,扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式,故8279的中断请求信号IRQ悬空未用。
-Scan button 82,798,279 plus 51 single-chip decoder 74LS 138 through the expansion of 4 × 4 keyboard, the display 6. From 3-8 decoder SL0 ~ SL2 translated to the key scanning line, by another 3-8 decoder translated display scan line, and uses code scanning. In order to prevent the emergence of the phenomenon of re-key, scan the output line does not take part in high level SL3 scan decoding keys. CPU on the 8279 surveillance using the query mode, the 8279 interrupt request signal IRQ left unused.
