clock
- This program implements a time-of-day clock using two cascaded MC14499 serial 7-segment display drivers.
count
- This program copies BCD data to four 7-segment displays driven by a MC14499 serial display driver. A 4-digit count is copied at a rate of 10 Hz. The interface uses the 68681 DUART to drive the MC1-This program copies BCD
PS7219
- 在以往大屏幕驱动电路的设计中,常采用单片机动态扫描或者是用MC14499等芯片组成的串行驱动,但他们存在的一个共同缺点是系统软硬件设计复杂,故障率高。选用PS7219芯片,可以显著降低系统设计的复杂程度,而且能更有效地保证系统稳定运行。 -In the past, large-screen drive circuit design, dynamic scanning is often used single-chip or othe
