  1. This project is an offshoot of an earlier investigation of wireless wearables using the MSP430G2553: http://forum.43oh.com/topic/10060-msp430-wearable-with-radio/. The concept has been successfully tested and is described below. I plan regular updates as the project progresses. The objective is to develop a wearable powered by a coin cell that can be controlled remotely. It could be used, as an example, in the tiara below or on a costume worn by dancers in a performance and controlled from offstage. In the photo an earlier MSP430G2553 coin cell powered wearable is attached to the tiar
  2. Hi, I'm trying to read analog values from a SHARP IR sensor GP2Y0A41SK0F using the MSP430F5529 launchpad. There was not any error when I verified and uploaded the codes in Energia. However, when I clicked on the Serial Monitor, nothing showed up. But when I chose the MSP430G2452 from the "Tools" menu, the monitor successfully showed the analog values. I connect Vcc (red wire) to 5 V pin, the ground (black wire) to GND pin, and the analog output (white wire) to P6.4 pin/A4 pin. The same thing also happened to the MSP430G2553 launchpad. It only works when MSP430G2452 is selected.
  3. Hello, I needed a large 3 digit display with remote control. All available didn't fit my needs, were quite expensive or not flexible enough. So I decided to create my own inspired by products I found. IR remote control looked simple and cheap enough, Seeedstudio sells some nice large 7 segment LED displays and prototype PCB manufacture in China doesn't cost much. First I LaunchPad prototyped the design with 8 channel serial LED driver, like SCT2168, and generic 3 pin IR receiver. I implemented NEC IR protocol with TimerA and bit banged serial display data output. All worked nicely
  4. Hello, I am very frustrated am i'm still on the project to decode the IR remote of my toy Heli. Unfortunately I'm stuck and I need your help in the conversion of the code below. Thanks for this great article! http://trandi.wordpress.com/2010/06/19/ir-remote-syma-s026-dedicated-board-v2/ Sending the Data through serial is a secondary problem, it 's more important for me how to decode the IR Signals //#define F_CPU 8000000UL #include <avr/io.h> #include <avr/interrupt.h> #define LED_PIN PB0 2 #define SERIAL_PIN PB3 4 #define IR_PIN PB4 11 //tsop31238 DataPin #define
  5. G’day, Looking for Energia IR code for the stellaris. Got the following 430 code http://www.jerrypommer.com/msp430_ir_command_decoder/ to Energia complie but not proficient in C to convert it to run on Stellaris Did a bit of searching and found the following http://forum.stellarisiti.com/topic/515-ir-remote-control-demo-project-for-the-stellaris-launchpad/ but it uses CSS So does anyone have some Energia code that will let me turn on/off a few Stellaris driven leds with a IR TV controller. Grant
  6. I follow your forum for a while now. I’m starting digital artist working on IR project at the moment. I was hoping you could advice me a bit as you are expert for Beagle Bone. I have design music application in Unity 3D. It reacts to 24 different keyboard inputs. Now I was hoping to be able to control it remotely. I was trying to make I arts installation that would use remote controllers sending signals to receivers connected to different GPIOS on the Beagle Bone. Receiver would get binary IR signal and send it to Beagle Bone GPIO. Beagle Bone would change it to key input and send it to
  7. MSP430g2553 ALL DOCUMENTATION BELOW Playing with IR receiver (IR Library from Energia) and RGB led. I cant write analog values to my RGB led without breaking the program. I connected the three outputs to analogWrite capable pins. All works great when writing 0 or 255 but the library stop working well when i try to write other value to make the color less bright. Then i read about timers and PWM. I notice my library use Timer1_A so i need to connect leds to pins capable of analog writing but using Timer0_A. These pins were three, but one is RXD of Serial and messed things up. So I changed
  8. Ok, I am out of ideas on this. I am going to start by saying, this works on an arduino uno, no problems. Then follow that up by saying this works perfectly on a launchpad with a 2553 in it IF I DO NOT USE THE IR LIBRARY. So this is what happens: Simple motor control for a two motor robot. Using the IR Library to receive commands from a remote control. I upload the code, and I can make both motors go full throttle, forward, or backward. The moment that I try to spin right or left, I get a quick "jerk" from both motors, in opposite directions (as I would expect) and then no
  9. IR Remote Control Demo Project for the Stellaris LaunchPad Evaluation Board A demo to read Sony IR remote control commands using TIMER1A and PORTA PA2 Requires an IR Receiver device( TSOP1738 or similar ) connected to PA2 and a TV remote control. What you will need: First you will need a reciever/detector device like the TSOP1738 from vishay. That particular device is tuned for a 38khz carrier (most common) but if you happen to have a 36khz or 40khz device it will probablay work too. The one I used worked fine at 3.6v and can be powered right off the board. It's a 3 pin device, GND, VCC an
  10. I'm trying to build a distance sensor using an IR Led, and a TSOP receiver that is run by my stellaris launchpad. However, I am not sure how to produce the 38KHz that is needed to drive the transmitter, and I'm unsure about how to run the transmitter, and read the receiver at the same time. Any help is appreciated!
