DRIVE CIRCUIT AND METHOD OF FLORECENT DISPLAYER

摘要

The method for driving the digitron utilizing cheap shift registers and program recorded on CPU comprises a first step for initializing a shift register (40) when the timer interruption is set, a second step for transmitting the data in the shift register to the shift register (41) through SIO terminal of a CPU, a third step for reading data corresponding to the digit variables and a fourth step for transmitting the read data to the shift register (41).
