The aim of this application note is to show to scan the 4x4 matrix keypad multiplexed with a four 7-segment display. The software attached to this application note scans the pressed key and displays it on the multiplexed 7- segment LEDs. This application note makes obvious Interrupt capability of ...

(1) This pin may function as either a JTAG port or a user I/O pin. If the device is configured to use the JTAG ports for in-system programming, this pin is not available as a user I/O pin. (2) The user I/O pin count includes dedicated input pins and all I/O pins.

This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources ...

Welcome to the software files for the ADS8361 to TMS320F2812! There are two project files in each of the folders McBSP, SPI and Both. Mode II and IV are explored using the McBSP port alone, as well as the SPI port. These projects are located in the SPI and McBSP folders. Modes I and III are explo ...
