2.8" TFT Touch Shield (capacitive) with two MCP4725 Breakout

Post by scott_fx »

Hello,

I'm designing a controller for my car's ac system. It is controlled with 3 analog inputs:
FAN 0v-off, 5v-100%
MODE 0v-dash, 2.5v-floor, 5v-defrost
TEMP 0v-cold/AC on, 5v-hot/AC off

I can get away with just two dac's and hardwire in some resistors to control the 'mode' functionality. My question is, will the 2.8" TFT Touch Shield (capacitive) work with two MCP4725 Breakout Boards since they all use 12c?

thank you,

scott

Yes. The cap touch shield uses address 0x38. The MCP4725 uses addresses 0x62 or 0x63. Make sure to run the MCP4725 at 5V.
