I am not very good at it. If you have professional technical problems and various other problems, please solve them by yourself, including but not limited to pcb BOM table, welding, purchase link, unable to flash firmware, ink screen does not display, distribution network interface does not display, weather forecast Not displayed, blah blah blah blah...

The firmware download address  is https://gitee.com/hishyboy/epaper-calendar.       The latest version is currently version 1.01.

2021.9.1 Modified the extra lines under the box of the day. If you want to brush version 1.01, you must brush version 1.0 first, because 1.01 does not contain the spiffs part.

2021.9.1 Fixed the display problem of public holidays and substituted holidays

              Fixed the issue of missing additions before the Mid-Autumn Festival

              Added public holidays and shift adjustments in 2022 (forecast version, you should remember to modify it if there are any differences after it is officially released)
