Help with 16-Bit LED Nixie Tube Driver (CH453) and Arduino Integration

Using Arduino LEDs and Multiplexing

Hello everyone,

I'm currently working on a project involving the 16-Bit LED Nixie tube Driver and Keyboard Control Chip (CH453) and I'm trying to integrate it with an Arduino. However, I'm running into some difficulties and would greatly appreciate any help or guidance.

After connect the 16 digits to ch453 i did scan using Arduino code
There i found 24 addresses what is that means
Do you have any code?? If you have that could you share with me

Please provide

  • a datasheet for the CH453
  • a wiring diagram

This is CH453 datasheet
Here also you can see circuit diagram

I think they did not implement a device address. Similar to the TM1637.

In this case you start the communication with the command instead of the device address. Now it makes sense that you find many devices when you scan the i2c.

There is a library for the CH423. Maybe this can be a starting point for this chip:

Can i write code using this library??
