Hi, 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.

Hi I'm an Electronic Engineer (Honours degree level) with almost 5 years experience developing embedded systems. I'm also an Automation engineer with a Rockwell Automation Certificate, you can learn more about me from my Freelancer profile. Sounds like you don't have the the negative supply of the ADC correctly specified, or you just need to incorporate negative values in your calculation also. Fortunately enough, I have a ChipkitUNO UC32 with me and a PCB which has the PIC32MX340512H on it to test it in hardware. I look forward to your reply. Kind regards V.T

That is not possible. Unless you are translating the values wrong. I will look into the source code to help see what is wrong. If I can find the problem immediately I will take the project. This is not possible. [update] I remember I had the same problem before when using this 18-bit Sigma-Delta ADC. Let me look into this.
