Your next embedded design idea has a new home. Curiosity is a costeffective, fullyintegrated 8bit development platform targeted at. The Line Follower Robot with Texas Instruments 1. Bit MSP4. 30. G2. Microcontroller. September 1. Robotics. When Texas Instruments TI introduced their new value line 1. MSP4. 30 Value Line Launch. Pad in the mid of 2. The datasheet collection for the ICs of the CMOS 4000 series. Watch nowUSD 4. 3. Therefore the introduction of the MSP4. Launch. Pad development board make a tremendous impact especially among the electronics hobbyist, students, and enthusiast because now the big boy TI is seriously taking part in the electronic hobbyist market and directly compete their 1. Atmel and Microchip. The MSP4. 30 Value Line Launch. Pad development board is come with the eclipse based Texas Instruments integrated development environment IDE called Code Composer Studio downloadable from the TI website and equiped with the professional grade C compiler and debugger, which make the development of MSP4. As you know most of the electronics hobbyist used the popular 8 bit class microcontroller to most of their embedded project such as AVR microcontroller from Atmel and PIC microcontroller from Microchip. Now you might wonder why we have to learn another type of microcontroller as most of the modern microcontroller has already provided all the necessary features that we need. Why not, learning another type of microcontroller is one of the fascinating and challenging topics to be learned especially for the true electronics hobbyist as this will broaden our knowledge and utilize what is the best on each of the microcontroller types to support our future embedded system project. The MSP4. 30 Microcontroller Project. After many considerations of what is the attractive way to introduce this MSP4. LED, I decided to built a simple and yet most popular robot,yes,is another Line Follower Robot LFR using the Texas Instruments 1. MSP4. 30. G2. 23. MSP4. 30 Value Line Launch. Pad development board. Because I think building a robot will give you the basic knowledge and understanding you needs to start explores many of the advance features offered by this 1. MSP4. 30 value lines microcontrollers by yourself. If you notice on the above picture this Line Follower Robot LFR used a similar CD chassis, DC geared motor, and sensors found on my previous articles The LM3. Quad Op Amp Line Follower Robot with Pulse Width Modulation. Therefore this project also serves as a good example of the digital version of the analog LFR weve built before. The following is the complete electronic schematic of the Line Follower Robot Now let list down all the necessary electronic components and other supported materials to build this LFR 1.
