How to interface touch screen and sd card to microcontroller

[Bhavani]

Hi all,

I need to interface touch screen and sd card to microcontroller “explorer 16 development board by microchip”. Coding needs to b done in C. I am a beginner in this regards hence I need a detailed suggestion. Looking forward yours inputs.

if you want file system on your Sd card then Fatfs library is your only opition.Dowload the sample code for your Controller family and modify it.

I have not worked with touch screen so i can't guide you on that.

resistive touch screen have 4 wire interface. it gives 4 channel analog output. you need 4 channel ADC external or internal to micro controller to detect the touch

Thanks for the reply. I want to know is it not possible to just read and/or write data onto sd card with out using any fatfs instead just establishing plain spi communication.

Hi,

I am aware of that but i want some info on how to implement in C by bringing the theory together.
