This is a demo of dual quad seven segment + LED + keypad module. The module has a 74LS145 and a 74LS164. Both of these digital logic ICs are used to decode keypad inputs and multiplex seven segment and LED states in a very simple fashion. The module is pretty small and cheap, and is a suitable replacement of MAX72xx, TM1640, etc.

These are demos of PT100 analogue transmitters. Two demos show how to use PT100 to 0 - 10V voltage and PT100 to 4 - 20mA current transmitters with MSP430F5529LP. In both cases, analogue voltages are converted to temperature data and shown on TFT displays. The codes are written with Code Composer Studio's C compiler.
