Version update points:¶
Version 1.2
① Version 1.2 updated the control of backlight on the basis of the original, the backlight of version 1.2 is controlled by STC8H1K28 microcontroller, and the backlight is lit in the program by sending the value to this microcontroller address (0x30). The values are 0x05, 0x06, 0x07, 0x08, 0x09 and 0x10, where 0x05 switches off the backlight and 0x10 is the maximum brightness.
② Version 1.2 has a new option for function switching, see above for details.
To set a different brightness level, you must first send 0x10 to turn on the screen, and then send another value to adjust the brightness.
Version 1.3
① Version 1.3 introduces an updated backlight control function. In this iteration, the backlight is managed by the STC8H1K28 microcontroller. The programme illuminates the backlight by transmitting numerical values to the microcontroller's address (0x30). Brightness adjustment spans 0-245 levels, where 0 denotes maximum brightness, 244 represents minimum brightness, and 245 disables the backlight.
The buzzer control principle mirrors that of the backlight: sending 246 activates the buzzer, while sending 247 deactivates it.
Version 1.4
Only the button component has been updated. All other hardware and I/O pins remain the same as in the previous version.
