Is there I2C communication for L203 model?
We are planning on buying Neuron Pi L203 for a company project. Hoping there is I2C communication between the expansion boards and the raspberry pi used as in one of the documentations it was mentioned MCP23008, although not for the L203 model. We wanted the product to use open source software and pogrammable with python, if there is an I2C chip provided in the expansion boards, we would like to be informed about the details of the chip so that we can be ready with the libraries for programming.
@HarishKumar In Neuron, the communication with CPUs that takes care of is using SPI. I2C and GPIOs of RPi are only in the UniPi 1.
@tomas_hora Thanks for your reply.
We would like to get the datasheet of the Neuron L203 model specifying the ARM CPU and their registers. We could not get the datasheet on the website.
@HarishKumar The internal communication is little bit modified Modbus, I suggest you to use the TCP Modbus: https://github.com/UniPiTechnology/neuron_tcp_modbus_overlay
The map of the TCP Modbus registers can be found at http://downloads.unipi.technology
