  1. 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
  2. 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(
  3. 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
  4. Attached find a driver for an HC-SR04 ultrasonic distance sensor (configurable for other similar devices) I had a lot of issues with the sensors operating very unreliably when they operate beyond max distance so there is a bit of additional code to handle this It supports single pings, multiple pings (with and without averaging) and a continual ping mode driven by a timer - so you can start it and then just check a variable at any time to get the most current measurement. Also supports returning statistics on the ping history I'm still new to Stellaris and C in general so probably more b
  5. 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
  6. 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
  7. 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
  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
