Built a framework for the popular Texas Instruments Ultra Low Power Microcontroller- MSP430 .This framework is like a shield for the microcontroller . This framework provides all major peripherals for any microcontroller at one place so that it becomes easy for a person to build small projects as he has access to the various IO devices and is ideal learning platform for beginners . I have used the TSSOP 28 pin MSP430G25553 as the microcontroller and have following peripherals on the board - Mic , Navigation Switches , LDR , 16*2 LCD Display , Capacitive touch , 6 Charlieplexed Leds , Buzzer , RGB leds (their intensity is controlled using PWM) , Pins for UART , SPI and I2C communcation in addition to the JTAG programming Pins. The board also features a stable power supply due to usage of 3.3V LDO and an amplifier circuit for the analog Mic . The schematic and Board Design was made by me from scratch on Eagle and then I also fabricated the PCB myself using the Tonner Transfer method in the TICEPD(Texas Instruments Center for embedded product Design) lab . After the fabrication , I also individually programmed and tested each of the peripherals . This project served as a great learning Experience for me .
Following is a brief Diagrammatic representation of the Framework Design -
Present below are the images of the board fabricated by me -
And now are the snapshots of the schematic and board layout for the above board made on Eagle Software -
