  1. Here's what has been keeping me busy (apart from my real job) since just after Christmas - a timed camera remote. It is mostly code complete, although could do with a few tweaks here and there. The hardware however isn't quite finished as I'm still waiting for a few parts to be delivered before I can finally finish it - the most critical of which is the 2.5mm stereo plug to go into the camera. Consequently it hasn't actually fired my camera yet, but I'm confident it will work correctly when the final parts arrive. Background Many moons ago, I created a serial port remote release for my S
  2. Hi, I'm Daniel and i'm from Colombia. I'm an electronic enginer student and i'm trying to make my own chess clock
  3. Hello, I was wondering if someone could help me create or find a delay function. I was thinking a 1ms delay function could work. I would like to have this, so that I can have some timed prompts on an LCD that I have working. Below is a fraction of my main.c I hope you guys can help me. main(){ LcdClrDisp(); LcdMoveCursor(1,4); LcdDispStrg("It is"); //-->Delay Function Here LcdClrDisp(); LcdMoveCursor(2,4); LcdDispStrg("Working :)"); //-->Delay Function Here } Thanks
  4. Hey all, I'm having some trouble with a project that checks a pin every hour and should trip a relay if a certain pin is HIGH. Some notes: - this is with the MSP430G2553 chip - it seems to run fine if duration is low (ex: 5000ms) - it worked at least once (triggered buzzer after an hour) when I replaced the relay circuit with a simple buzzer I'm using this relay circuit: And this code using TwoMsTimer library: #include <TwoMsTimer.h> unsigned long duration = 3600000; int relayPin = 14; int moistPin = 15; int state = 0; void setup() { pinMode(
  5. This is just the start of my project. Ultra sonic distance sensor, based on paralax ping sensor or other ultra sonic distance sensors . 24Khz and 40Khz ultra sonic transducer. Basic operation: Send Pulse--> wait for echo --> read time between pulse and echo --> send distance --> start over. completed part of projct at the time of posting. Output amplifier--completed PWM output (24Khz) --completed Parts that need to be completed Input amplifier/opamp -- waiting for jfet opamp, considering a 741 just for testing purposes pulse length code -- was workin
  6. Hello is there a similar library in energia ? http://playground.arduino.cc/Code/SimpleTimer or how can i execute a piece of code for X seconds. Thanks sirri
  7. Hello, I wrote my own first program. The program calculates the 16-bits timer for MSP430. Program is written in Java and tested for OpenJDK and JDK for Ubuntu and Windows 7. Program can save code to file. I hope that it will be useful for beginners. Download: http://www.chiptron.wz.cz/software.php CalcTimerMSP430.zip
  8. I need to measure the speed of a encoder, which creates pulses approx. 4 times per second. I'm not sure whether the timer can do that, or how to code it. The encoder is connected to the MSP, and i get signals in the 'coolterm' for testing purposes, but i need to figure out a way to get the timer to measure the time (ms) between each pulse. Thanks in advance Jais
