Hello, thanks for the quick response. I did place the library at top. It seems that the problem is within E18, as neither of the two SPI examples did compile. I had a E17 zip, so used it instead and it compiled like a charm. Thanks, will share any update on my project here, as I'm planning to do a parking access with the C3200, the RDIF card reader, and a 7 segment 4 digit display for counting the slots availables and a H bridge for controlling a stepper to give access.

Hello there, this is my first post. I'm very interested in your code, but I get this error: " Energia: 1.6.10E18 (Windows 10), Board: "CC3200-LAUNCHXL (80MHz)" <command-line>:0:15: warning: ISO C99 requires whitespace after the macro name [enabled by default] C:\Users\Alexander\Documents\Energia\CardReader\CardReader.ino: In function 'void setup()': CardReader:52: error: 'SPI' was not declared in this scope SPI.begin(); ^ exit status 1 'SPI' was not declared in this scope " Any ideas? I want to use the cc3200 to upload data, like text embeded on the rfid tag. T
