cyclone 10 LP evaluation Kit を使っています。 ARDUINO_ANAに入力されたアナログ信号値は "0x5E"のアドレスに格納されるとのことですが，アクセス方法がわかりません。教えてください。

Hi @kkama7​ , I am not sure I understand the problem statement. Firstly, C10LP does not support analog input, and secondly what/where is 0x5E?

[kkama7]

Thank you for your reply.

Although C10LP does not accept the analog input, C10LP-EV kit supports it via I2C communication from the max 10 device on the board.

The address "0x5E" is the register-address of I2C for the ADC of the max 10 device.

If you know samples about using I2C on C10 LP or LP-EV kit and tell me about them, I will be grateful.

Thank you.

Hi @kkama7​ I am not the expert in I2C, but i suppose you will need I2C controller IP in order to read access 0x5E.

I would presume you will need to follow the flow as in
