lorenzo cervelli / Mbed 2 deprecated DisplayTemperature_Max7219-Max6675_SD

A program to measure the temperature using the Max6675 board. The temperature is shown on 8x8 Max7219 matrix display and it is saved on SD as well.

Dependencies:   MAX7219 SDFileSystem mbed

Fork of MAXREFDES99_demo by Maxim Integrated

The program measures the temperature using the Max6675 board designed for Arduino. The temperature is shown on Max7219 8x8 matrix display (designed for Arduino as well) as text marque from right to left. The fonf size is 5x7 so the last row is used to show some info:

- All leds off: Normal temperature measuring - Leds shifting: Saving on SD card - Leds blinking: SD card missing or damaged

The Blue "user button" is used to save measured temperature on SD card. First click start saving, the second stop the process. Together the temperature is saved also the time. The time is reset when the process start. Connecting the USB to PC it's possible to see instant temperature and all saved data on SD.
