Features:
This module is designed by oneself. It drives 8-bit common negative digital tube, scans 24 buttons, and assembles a single chip microcomputer STC15W
So as to avoid the trouble of writing and driving the single chip microcomputer outside.
In addition, there is also a power indicator, single-chip microcomputer-driven running indicator, buzzer and the remaining two feet of TM1638 drive LED respectively, so that the TM1638 chip hardware interface has been fully used.
This module has brought out the communication interface of STC microcontroller IO and TM1638, which is more convenient for experiment.
This module can meet the experimental requirements, especially the early product development as a human-computer interaction panel, adjusting / testing machine is very convenient.
There are two ways to connect the external module to the module.
1. After transferring TTL through external serial port and communicating with microcontroller on the module, digital tube display, keyboard value and other resources on the module can be controlled.
2. External direct write driver and TM1638 communication.
