8-bit VFD screen driver board sharing has been verified ok

Overview

After seeing a lot of VFD screens, I started to get a little idea.
The clock demonstration video address is https://www.bilibili.com/video/BV18B4y177uW/?pop_share=1&vd_source=60d77ffb40694c0d6a69eb11f751fcb5
. Let's start with a smaller one. The big guys in the group shared open source programs and solutions for this screen before. After seeing a lot of VFD screens, I started to get a little idea. Let's start with a smaller one. The big guys in the group shared open source programs and solutions for this screen before. I also followed their tracks. . . The original open source version is a little different from the use of esp8266 that I recently came into contact with. So I updated the esp8266 circuit according to my plan, and also calibrated the gate and anode voltages according to the instructions (I used MT3608 for this boost, which has two sets of resistors, one set is 68K+2.2=19.5V and the other is 140K+4.7=20V). Thanks to LiChuang for always supporting us with free boards. LiChuang also gave us discounts. The 20 10k resistors on the screen are from SMT. Here are some programs to upload. A lighting program. A clock program for the group.
