App note: Implementation of a single-phase electronic watt-hour meter using the MSP430AFE2xx

Another energy meter from Texas Instruments using MSP430AFE2xx. Link here (PDF) This application report describes the implementation of a single-phase electronic electricity meter using the Texas Instruments MSP430AFE2xx metering processors. It includes the necessary information with regard to metrology software and hardware procedures for this single chip implementation.

Magic Mote MSP430G2553 wireless sensor node with NRF24L01+ module

Tom from Magic Smoke writes: This is my first time designing a PCB for MSP430. I really like the NRF24L01+ booster pack but I would like something smaller to use for remote temperature sensors. With that in mind I’ve designed a 24.5 x 50 mm PCB (2 on a 5×5 cm prototype) featuring MSP430G2553 and […]

App note: 1-μA capacitive grip detection based on MSP430 Microcontrollers

An app note from TI, 1-μA capacitive grip detection based on MSP430 Microcontrollers (PDF!) This application report  discusseshow to design a simple and ultra low-power grip detector Booster Pack for the MSP430 LaunchPad. The PINOSC feature in every msp430G2xx2 and msp430G2xx3 device makes it possible to eliminate all the external components when implementing a capacitive […]

TruPlay- Hacking into an OVC3860 based bluetooth A2DP adapter using the MSP430

TruPlay –  controlling bluetooth A2DP devices using MSP430and OVC3860  from Rohit Gupta: I wanted it to 3D Print a new case but couldn’t so, made a PCB that would sit on the Top of the adapter and command it. I was lucky to have a 3.3V Regulator inside the adapter so, an extra regulator was […]

FM430 – A MSP430 and TEA5767 project that lets you listen to clear digital FM

From the comments on our earlier FM radio receiver post.  Rohit Gupta shows off his digital FM Receiver on MSP430 using TEA5767: I completed one yesterday using the MSP430 and TEA5767 Chip. Gave it a minimalist switch to toggle the channels stored in an array. Gives realtime channel strength and transmission quality values too over serial. […]

App note: Interfacing the KXP94 or KXR94 tri-axis accelerometer with the Texas Instruments MSP430F149 microprocessor to measure tilt and other motions

Capture motions with Kionix’ Tri-Axis Accelerometers and a TI’s MSP430F149. App note here (PDF) Kionix linear accelerometers function on the principle of differential capacitance. Acceleration causes displacement of a silicon structure resulting in a change in capacitance. A signal-conditioning CMOS technology ASIC detects and transforms changes in capacitance into an analog output voltage which is […]

Magic Mote wireless sensor v2

Tom posted an update on his Magic Mote wireless sensor we covered previously: Here is Version 2 of the Magic Mote PCB. The tactile switch is more accessible at the side of the board, the programming/serial header is now IDC6 compatible, and there is improved isolation of the ground plane under the watch crystal.

Magic Mote thermostat and wireless temperature sensor

Tom’s another cool project the Magic Mote thermostat and wireless temperature sensor: A homemade thermostat up in the basement rafters controls the heating in my home. The smart bit is the radio frequency communication that connects it to a remote temperature sensor. So, I’m planning a home automation system based around wireless nodes (the Magic Mote […]

Wireless sensor node with MSP430G2553 and 8-pin adapter for NRF24L01+

Tom has designed this Magic Mote wireless sensor, that is available at Github: I set out to design a wireless sensor PCB that could be inexpensively prototyped in quantities of 10. NRF24L01+ modules are exceedingly cheap (~$10 for 10), use very little power, and have sufficient range for most indoor projects. Low power MSP430 microcontrollers make an ideal […]

Accurate-ish Pneumatic cylinder positioning with flow meter, ATX breakout and MSP430 LaunchPad

arduinoversusevil writes: We’re using the 43oh to control 12V solenoids supplied from a Dangerous Prototypes ATX breakout, and the Adafruit flow meter is feeding back position data to the 43oh. Surprisingly IT WORKS! For more build deets visit the blog Check out the video after the break.

Dot-Matrix MSP430 alarm clock update

Markus Gritsch posted an update on his Dot-Matrix MSP430 alarm clock we covered previously: Using the ADC is a good suggestion. Thank you! The clock now has an additional state after turning the flashlight off, where it displays the battery voltage in volt. I also added an additional displaying mode where it uses dice symbols for […]

Cheap frequency counter based on MSP430

SUF posted a cheap frequency counter based on MSP430 in the project log forum. Here is the properties of the project: – Cheap: The component total should be below $5 – Using TI’s MSP430 line of MCUs what I’m learning now – Able to measure till 10MHz – Using LED display – Able to calibrate – […]

Sensorless Brushless DC Motor Drive with MSP430

A booster board for the MSP430 LaunchPad controls brushless DC motors with or without sensors. A bunch of double NPN transistor MBT2222AD ICs drive the motors: I thought that I would share my project on the forum. I call it BLDC Booster. It is a booster pack for the MSP430 LaunchPad that allows for sensored […]
