I am currently using the tiva c (EKTM4c 123 GXL) launchpad to read data from Mifare RC522 RFID card readers. I wish to know how I can possibly read this data and then store it in EXCEL format so that later I can port it to a MYSQL data base. or is it possible to port the data directly to the database.
Thank you Mozart Alea
You don't need to go through Excel to import data into MySQL.
But one file format to consider is a traditional CSV - Comma-Separated Values - file where you have one data record/line. Easy to generate and a huge number of programs can import. Including Excel.
Anyway - why don't you start with googling for how to import data into MySQL. Then look for the solution that is easiest to perform based on your original data source. You are seriously complicating things if you want your embedded program to create native Excel documents. That just indicates that you have locked in on a specific solution instead of taking one step back and instead invested time looking for available and suitable solutions. It's even easier to directly have your embedded program print SQL insert statements than have it generate native Excel documents.
