Msp430 Examples

Notes: 1) I have cut and paste the LCD functions from projects I have already done. The extra features such as direct cursor positioning will come in handy in the future.

2) While the display shown has 16 characters x 2 lines, the code is written to be compatible with 1, 2 or 4 line display modules. 3) The test program outputs two messages, title1 and title2 on the LCD and then flashes an LED on P1.0 (pin-2) at about 2Hz. 4) Note that the supply voltage on the MSP430G2553 is +3.6V while the supply voltage for the LCD is +5V. I will have to source LCDs that run at +3.6V. In the next post, I will create a 'dumb terminal' application that accepts ASCII text via the UART RXD input and displays this on the LCD screen. This is extremely useful for debugging embedded systems.

What is all this talk about a silly little Timer? The Timer keeps track of how many clock cycles pass without having to write specific code to keep track of time. Akvis Retoucher License Crack Software.

This can be useful not only for low power modes, but also for time sensitive projects. To keep it simple and quick, a timer needs to be initialized and enabled. It will then proceed to count as the clock ticks to a predefined value and then start over.

Wilson Golf Club Serial Number. You can set the Timer to generate events at multiple times along the way to its end value; these events could be an interrupt when it hits a certain number of clock ticks, or it can toggle, set, or clear a specialized pin. Having the Timer change a pin without calling any interrupts or any specialized code is the best way to create a simple PWM.

In order to visually see this in action, which I'm guessing a lot of you do, you can use either a Logic Analyzer,. So lets hook up the LED. Since we are limited as to which pins we can hook up to the timer using this method (we can't hook up P1.0), we will need to hook up P1.2 to one of the LEDs on the LaunchPad. I'm hoping that you have installed headers (either male or female) onto the LaunchPad already. Take out the jumper which is above one of the LEDs and then hook the LED to the pin P1.2 on the board. If you are having trouble with this, write a comment, I will help you. @TDU, Out of curiosity, I checked to see what happens when you set LPM0 and LPM4 together.

If you check the header files, LPM0 would put 0x0010 to the SR. LPM4 puts 0x00F0.

LPM0 + LPM4 puts 0x0100, which leaves all the oscillators running and sets the V bit (which I believe is normally used to mark carry over from additions). The best thing to keep in mind is any LPM includes all the previous LPM's-- eg.

LPM0 and LPM1 are subsets of LPM2. I ran some example code on my LaunchPad and confirmed that this is indeed the case; just watch the SR register in debug mode and you'll see what's happening.

Daniel @NJC Hopefully you still check this even though this post is a few months old. First, thank you for the work you do on this blog. As a student I know you are very busy and I appreciate the time you sacrifice for this project. As was already pointed out in another comment, LED2 on P1.6 can be used for pwm (P1.6 has compare functionality for Timer A).
