You need to modify IRremote.cpp under "\hardware\msp430\libraries\IRremote".
After the TIMER_PIN_SELECT();
Comment these lines :
 
// pinMode(TIMER_PWM_PIN, OUTPUT);
// digitalWrite(TIMER_PWM_PIN, LOW); // When not sending PWM, we want it low
 
The pin output is P2_3. For the demo you need to send something on serial to transmit.
 
PS: Tested and working IRrecv and IRsend with 2xmsp430g2553.
 
Hope it helps,
Have fun

Hello,
 
I just recieved the c2k launchpad today, looking forward to test and learn more about it, i`m glad i found this forum
Mihai

Hi,
 
Here's a simple example (based on a crossover of TI;s example code External_interrupt and LaunchpadDemo) that detects a buttonpress on the C2000 Launchpad (GPIO12), processes the press in an interrupt and shows the no of buttonpresses using the Port_A LED setup. The button isnt properly debounced yet it seems but its working. The code isnt the shortest possible I guess.

Hello,
This is my first very simple test with the c2k launchpad, it simply lights up a led (gpio0) a turns it off when the button (gpio12) is pressed.
Below is my code for it. Hope you like it.
 

// // c2k launchpad led Hello world 1.0 + button // //includes #include "DSP28x_Project.h" #include "f2802x_common/include/clk.h" #include "f2802x_common/include/gpio.h" #include "f2802x_common/include/pll.h" #include "f2802x_common/include/wdog.h" #ifdef _FLASH memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize); #endif //main void main() { //wdog WDOG_Handle myWDog; myWDog = WDOG_init((void *)WDOG_BASE_ADDR, sizeof(WDOG_Obj)); WDOG_disable(myWDog); //clk&pll CLK_Handle myClk; PLL_Handle myPll; myClk = CLK_init((void *)CLK_BASE_ADDR, sizeof(CLK_Obj)); myPll = PLL_init((void *)PLL_BASE_ADDR, sizeof(PLL_Obj)); CLK_setOscSrc(myClk, CLK_OscSrc_Internal); PLL_setup(myPll, PLL_Multiplier_12, PLL_DivideSelect_ClkIn_by_2); //set gpio GPIO_Handle myGpio; myGpio = GPIO_init((void *)GPIO_BASE_ADDR, sizeof(GPIO_Obj)); //set led gpio0 GPIO_setMode(myGpio, GPIO_Number_0, GPIO_0_Mode_GeneralPurpose); GPIO_setDirection(myGpio, GPIO_Number_0, GPIO_Direction_Output); GPIO_setHigh(myGpio, GPIO_Number_0); //set button gpio12 GPIO_setMode(myGpio, GPIO_Number_12, GPIO_12_Mode_GeneralPurpose); GPIO_setDirection(myGpio, GPIO_Number_12, GPIO_Direction_Input); GPIO_setPullUp(myGpio, GPIO_Number_12, GPIO_PullUp_Disable); //loop for(; { // if gpio12 button is pressed led on-off once if(GPIO_getData(myGpio, GPIO_Number_12) == 1) { GPIO_setLow(myGpio, GPIO_Number_0); DELAY_US(1000000); GPIO_setHigh(myGpio, GPIO_Number_0); } } }

I would use it to control stair lightings with led`s on every stair and 3 ir sensors, bottom, top and in the middle, if one of them is activated the led`s will light up in order depending in witch direction you are going and wait untill you reach the seccond sensors then power down in the direction you went, if both sensors are activated in an amount of time the led`s will all light up. Manual control will also be posible and seting up the delay, a future desired project will be comunicating with my ez430 chronos watch, manual overwrite control of the stairs and detection if a person activates one of the sensors.
Another project that i would like control my shower lights, audio(radio or mp3), and fan control if it gets too hot, by saved presets ( one for me, one for my girlfriend and one for both ) interfaced with the pc.

Yes google showed me the way after searching all around ti.com for resources
