Master Control: ESP12F;

Screen: Using a 7P 0.96-inch OLED screen display, the screen uses SPI communication, which has a faster speed limit compared to IIC communication.

Battery: Built-in 3.7V-400mAh-702025 lithium polymer battery, with a battery life of about two hours.

Power Management: Using the ETA6003 power management chip, it has dynamic power path management function and can be used continuously without worrying about battery life loss. The indicator light flashes when charging, goes out when fully charged, and flashes when there is no battery.

Switch: with battery switch;

Battery power detection: Integrated ADC sampling circuit can measure battery power.

First, reflow solder this surface.

Manual welding of remaining components (toggle switch, buttons, screen surface).

Test the fit between the small board and the rear cover shell.

Two plates are welded and fine-tuned vertically.

Visually vertical.

Screen soldering.

Take a look at the overall effect at this step.

Battery welding.

Assembly.

You can consider whether to glue the back cover. Recently, several small TV back covers have some small gaps, so I glued the back cover of one of them together.

Welding assembly completed.

Download the attachment "[Code and Burning] ESP8266 Weather Clock _ Autonavi API_7.00.zip" and execute this batch file in the following path to complete the automatic burning.

ESP8266 Weather Clock Burning Display Effect:

You can refer to the following open source projects for using Arduino burning programs and uploading web page files to SPIFFS using the ESP8266 Sketch Data Upload plugin.

Firmware burning using NodeMCU-PyFlasher:

Install CH340 driver.

2. Use a data cable to connect the small TV and computer;

Three steps to enter download mode: ① Press and hold the upper button, ② Press and hold the lower button, ③ Release the lower button, ④ Release the upper button to enter download mode.

4. Unzip and open the NodeMCU-PyFlasher.exe file of "Programs and Burning Tools.zip" in the attachment as follows:

After the first successful burning and resetting the small TV through the lower button, the following three interfaces will appear in order:

When the small TV starts, when the second interface appears, it will automatically enter the network distribution mode. At this time, the small TV will automatically create a hotspot named "wifi_link_tool". After connecting this WiFi with a mobile phone or computer, the network distribution page will pop up. The operation is shown in the following figure.

After clicking "Configuration complete, restart and jump", the small TV will automatically restart and connect to the network to obtain the time. The network configuration is completed. At this time, your mobile phone or computer and other devices can disconnect the WIFI of the currently configured small TV.

Regarding the issue of distribution network:

If the small TV still cannot obtain the time after the network connection is completed, you can try to restart the small TV (press and hold the button below to reset, that is, restart) under the premise of ensuring that the network can be connected to the Internet.

If the small TV needs to switch to WiFi and reconfigure the network, just press and hold the button on the upper side of the small TV for about 10 seconds while it is turned on to enter the network configuration mode.

Debugging:

The serial port assistant can be used to obtain information such as the date, time, battery voltage, and battery level of the small TV.
