Version update points:¶
Version 1.1:¶
① Version 1.1 updated the control of backlight on the basis of the original, the backlight of version 1.1 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.
**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. **
The buzzer and speaker operate on the same principle as the backlight control: sending 0x15 activates the buzzer, while sending 0x16 turns it off. Sending 0x17 turns the speaker on, and sending 0x18 turns it off.
② Version 1.1has a new option for function switching, see above for details.
Version 1.2:¶
Version 1.2 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 and speaker operate on the same principle as the backlight control: sending 246 activates the buzzer, while sending 247 turns it off. Sending 248 turns the speaker on, and sending 249 turns it off.
Version 1.2: Other hardware and pin configurations remain unchanged. The button components have been updated; the buttons are now shorter, and the casing has been modified accordingly.
