Came across this while browsing. MSP430 Analog Gauge Clock

I'm trying to test the clock functionality available on TIRTOS for the CC1310 SOC from Energia but I'm finding difficulties to make the clock trigger periodically (every 5 seconds in the example). This is what I'm doing so far: #include <ti/sysbios/knl/Clock.h> #include <ti/sysbios/BIOS.h> Clock_Params clkParams; Clock_Struct clkStruct; Clock_Handle clkHandle; Clock_Params_init(&clkParams); clkParams.period = 5000000/Clock_tickPeriod; clkParams.startFlag = FALSE; /* Construct a periodic Clock Instance */ Clock_construct(&clkStruct, (Clock_FuncPtr)clkFxn, 5000

MSP432 Hi, For the MSP432, in the newer release of energia, is there a way to change from the internal clock to the high-frequency crystal oscillator? Or is there a way to set the DCO clock to different frequencies? (end goal is to use a reliable clock (to time up to 15 seconds) for interrupt control and spi communications) Thanks!

This piece of code was made possible by Trey German, Robert Wessels, and Cathy Wicks of Texas Instruments. Without Trey's knowledge and Cathy's encouragement, I wouldn't have been able to make this program. Robert is the one who told me about this project. When creating 430AlarmClock, I adhered to my usual procedure for designing programs: 0. Make a general outline 1. Get the hardware 2. Write the basic stuff 3. Tweak, test, repeat until it works 4. Add/remove/tweak more advanced features until you are satisfied 5. Publish, add license, do whatever else you need to do I made the outli

I am currently working on a project that uses the external crystal for the watchdog timer and the internal DSO clock for all other tasks. The crystal is 32kHz. The watchdog timer interrupt is taking care of controlling the state machine in the main loop. At first sight everything looks ok. However, after a while (hours later) the controller (MSP430G2553) appears to be stuck. Closer investigation show that this is due to the watchdog timer interrupt not served, means that the 32Khz clock is not present. I already tried to play with the XTAL capacitor settings to no effect. I am wonderi

MSP430 based Nixie tube clock. I was looking for some nice Nixie tube digit images so I could add them to my EduKit library, but I couldn't find any usable ones. I decided to just buy few of them and photograph myself. Then I thought that it would be a horrible waste if they just sit in a drawer. So here it is, my first Nixie project since... 1987. This clock will be available as kit, but since this is v1, I will most likely make some adjustments. Any suggestions are welcome.

Hi everyone! This is my second time on the forum. The first time i was here it was to ask for help with interrupts and an LED display. 43oh was very helpful and I accomplished my goal. Today I am here to ask for help again. Goal: Implement the code previously written into the chip only and drive it without the development board. (breadboard mode) I did some research and most post/websites told me that all i need is 3.3V and a 47k resistor going from VCC to the RST pin on the chip and that my program would start working... I tried this and it did not. reference:http://crossplatform

Hello there, *new* Found out the speed of my clock. The problem now is I don't think my interrupt is working. *new* I am doing a project where I have to read in a square wave and determine the frequency of the wave then output that number. I was wondering if someone could help me out by telling me what the base clock speed is. I am programming through energia, idk if that will effect the speed at all, but just in case I am. Hope someone can help me out Thanks a bunch!! if you don't know what energia is energia.nu is where you can find information My code so far

This project is an update to the binary clock that I used on my desk. The new version has a lot of new features including RGB leds(WS2812), a bigger microcontroller(The Olimexino-5510 board), capacitive touch and light sensor. My first idea was to have something based on the MSP430G2553, a couple of WS2812 leds and capacitive touch. But after comparing the work i would have to do, and very few rewards to the Olimexino-5510 functionality I quickly reconsidered. The Olimexino-5510 provides quite a few things I wanted: MSP430F5510 Battery Charger USB capabilities Arduino Form Factor So all I ha

Hi there, I would really appreciate any help here. Assuming ClockVal defined as unsigned long Clockval=0 After executing this 2 lines of code... SysCtlClockSet(SYSCTL_SYSDIV_5|SYSCTL_USE_PLL|SYSCTL_XTAL_16MHZ|SYSCTL_OSC_MAIN); ClockVal = SysCtlClockGet(); What should be the correct value of Clockval? A friend of mine reported 40,000.000 meaning 40 Mhz using IAR, in my case running Keil I get 3,200000 or 3.2 Mhz, does abybody have a clue for this weird value?? Thanks a lot in advance Simao P.S. 1) We both use Stellaris LM4F120 LaunchPad Evaluation K

Hi guys Here I am again to ask for help :oops: So the deal is this: I'm waiting for a nokia 5110 LCD screen to arrive and I'm thinking on what I can do with it. My idea was to make something like a clock with a thermometer and, with an accelerometer, when I bounce it it works like a magic 8 ball (I think about a decision I have to make and it "helps" me with a "Yes" "No" and "Maybe" answer). The maginc 8 ball isn't a real issue. I gess that the code is pretty simple (I can use a sample code from the book "Getting started with the MSP430") and that shouldn't be a problem. My pr

I'm working on incorporating the option to sync time from a GPS source for my VFD clock. I wrote the code stand-alone for testing - thought it might be useful for some others on the forum. The code is based on oPossum's RTC clock code. Date/Time values are BCD. It could probably be converted to decimal time as well, but BCD works best for my application. A main time variable is available - and would normally be updated through a 1hz timer interrupt, although the interrupt isn't included in this code (I'll probably add that later as an update - but the code to do that is pretty easy).

I figured you guys might be interested in some of my tinkering with the Launchpad. Hopefully by putting a few of my projects up here it will also keep me accountable for finishing them. This is one a cobbled together a few months ago. It's been up on the MCU projects page on E2E, so you might have already seen it: http://e2e.ti.com/group/microcontrollerprojects/m/msp430microcontrollerprojects/664670.aspx PROJECT OVERVIEW The Vetinari clock is from a book series known as Discworld, where Lord Verinari has a clock in his waiting room which has an irregular tick. The idea of the clo

Found this through hackaday. Sunrise Alarm Clock. Uses a G2553 (Programmed via Launchpad) Uses a DFC-77 Atomic Radiowave Time Receiver for, well, atomic time. Standard Character LCD (via a shift register) (and pwmed backlight) Settings through Pushbuttons Simple Alarm via PWM melody. 10mm LEDS to provide Sunlight (These could/should be replaced with high current 1a/3a type leds imho) And battery backup (with backup status recognition on p1.4 interrupt) via three diodes! A full featured project, though it could use better leds, and unless you are in Europe, a different cloc
