PIC32MX340512H and MCP3424 software modification


I have software for microcontroller PIC32MX340512H which reads data from A/D converter MCP3424 via I2C bus. The program only works properly if MCP3424 measures a negative value. In this case, PIC32MX340512H displays the correct value. If MCP3424 measures a positive value (voltage), PIC32MX340512H will show an incorrect value.

For example: if I connect -1.5V voltage to MCP3424, then PIC32 will show -1750 what is fine.

If I change the polarity, then pIC32 should show a value of 1750, but instead show a value of -15. I need PIC32 to show 1750 in this case.

Your task is to edit the code so that PIC32 shows the right value for positive and negative voltages.

That is all.

PS: I have 2 boards (with PIC32 and MCP3424) where I can test this software.
