Notes: 1. The VDD value depends on the power supply voltage of the microcontroller used.

Adjust the values of the constants R1, R2, R4, C1, and C2 to the power supply voltage

used.

2. The VFL value depends on the fluorescent display tube used. Adjust the values of the

constants R3 and ZD to the power supply voltage used.
