    Developing a simple program - Code composer studio V3.3

    Hi, I was successful in making F2812 custom board and also could get connected thru the XDS510LC emulator. As I am new to F2812 I felt prudent to take small steps. In that direction started trying out the Lesson 1 of CCS V3.3 tutorials -Developing a simple program. I could create the project...

    Driving LED's using CD74HC595 shift register

    Thanks Mandar for the info. From the program I could understand that the shift register is connected to serial port SIMO / SOMI. Am I right?. However I have a query. I have connected the shift register to GPIO pin of the processor. Could this be implemented?. Please suggest. Thx :D

    3.3V to 15V PWM level shift

    15v level translator Hi, I would need to drive a mosfet driver which needs 15V PWM signal. However the microprocessor would provide 3.3V PWM supply. Any idea how to amplify the signal. Thx KV

    SIPO and Darlington Array

    Hi, I intend to implement a shift register and darlington array for controlling 15 relays sequentially. I am not sure though if I could control 15 relays with 2 SIPO's being driver by the microprocessor. Could anybody review this and comment. thx & rdgs
