    Jessters got a reaction from dacoffey in Custom target board for cheap MSP430 development   
    Haven't been on the forum for a few months, been busy with a few projects for work(which I probably could have gotten some help with here had I bothered to log on... heh). Good to see the forum is growing. And experienced guys, get ready for a possible bag full of questions as I get started on a new project here shortly.
     
    On another note, here is a recent MSP430 based project I just wrapped up. Previously we had needed to purchase 7 separate TS430PM64 target boards to be added to projects on a permanent basis. As the target boards directly from TI can run 75+ USD my business partner and I decided to make our own. Essentially, I designed one main board that can be added to any project on a permanent basis, and runs less than 10 dollars to make. Since we work on industrial projects, this board is usually on the inside of aluminum frame and housing. Hence the need of a "permanent" addition, while still allowing for debugging and programming.
     
    A second board, which consists of a MSP430 of just about any 64PM variation, a 3.3v reg, and a crystal can then be plugged in to the main board. The reason we did it this way is that the main board itself can support various different MCU variants, but the Yamaichi clam shell socket for those MCU's runs around 90 dollars. Adding one of those completely defeat the purpose of the project due to cost. Simply making the secondary board and adding various MCU's as needed was MUCH more cost effective. In the end it came out as a set up similar to the old BASIC Stamp break out boards. But works seamlessly for what we needed.

    Jessters got a reaction from RobG in LaunchPad, DC Motor, PWM   
    Have had the same problem off and on. I have needed to design a few H bridge implementations for several different projects, and while not all ran off the LaunchPad, all were MSP430 projects... so the same 3.3V issue. I have ended up using a buffer and inverter as standard practice to; A) separate the MCU from the rest of the circuit, and rectify the VCC issue, and cut pin count per motor down to 2 pins. The attached circuit doesn't even require a reference ground to the MCU. The final product in regards to that schematic has a pair of 24v 8Amp DC motors running off PWM output from a G2231 MCU.
