The installation consists of several water level sensors 4-20mA connected to the 4-20mA Current Receiver PR33-15. The setup with the Arduino Uno has the I2C-Shield PR 14-3 on top of the Arduino Uno, the I2C-Shield is connected to the receiver PR33-15 with I2C-cable. The sketch for Arduino Uno includes the MCP3428.h - library and works without problem.
Given the limitations of the Arduino Uno, I want to migrate the installation of the sensors to Arduino Due, accordingly replace the I2C-shield with the PR37-10 for the Due and connect the PR33-15 receiver with I2C-cable, the I2C-OUT1 at the PR37-10 to the I2C-IN at the PR33-15 receiver . The jumpers on the I2C-shield according to the wiring diagram placed to use the I2C-port 1. Unfortunately the sketch does not work, as soon as the MCP3428 is declared with the instruction: MCP3428 MCP(0); The execution of the sketch hangs, as soon as the declaration of the MCP3428 is carried out.
Is there any incompatiblity of the hardware above or is there any setup-mistake concerning the connection of receiver and I2C-shield ? What about the library MCP3428.h, is this one correct with the Arduino Due ? Is the declaration of MCP3428 with: “MCP3428 MCP(0);” correct ?
