Since it also has a processing section 6, the control device 16
The burden on the main MCU 17 is reduced, and wiring connections become extremely simple. i.e. main MCU
Reference numeral 17 controls a continuation switch 19, a 10 count switch 20, a starting port switch 21, a drive solenoid 22, an electronic sound generation circuit 23, a lamp indicator 24, etc. provided on the center accessory 18, etc. Processing unit 6 included in display device 1
receives data and a reset signal from the main circuit, controls each LED element 9 arranged on the display board 4, and displays a predetermined pattern, character, etc. still,
In this embodiment, a real-time reset method is adopted to prevent runaway caused by noise, the timer circuit is omitted, the reset signal is received from the main MCU 17, and the 8-bit data is divided into 4 bits and transferred twice, thereby reducing the number of connections. is decreasing. According to the present invention, 4 data lines, 2 power lines,
A total of 11 wires is sufficient, including one reset, one interrupt, and three control signals (8-bit upper/lower, bright/dark, digit selection), but if you rely on the main MCU 17 as in the past, you will need at least 40 wires. is necessary. Also,
If each LED element 9 of the display device 1 is controlled by the main MCU 17, the processing time becomes long and the display flickers and becomes difficult to see.

Then, as shown in the flowchart of FIG. 5, the processing unit 6 built into the display device 1 initializes the I/0 port, determines whether the reset signal is to be reset by power-on or by an interrupt, and resets the ram ( RAM), exchanges the upper and lower 4-bit data input by non-maskable interrupt (NMI) with 8-bit data, resets the free-running counter, exchanges the above 8-bit data with symbol data, and sends the data to each port. It outputs as brightness information and updates the data for scanning the LED rows of each display board 4. For example, when scanning a horizontal row 10 times and the free running counter is greater than 819, it jumps and the light emission time for one time is 819 μS.
