Hi,
 
I have found an excellent tutorial about PWM on Stellarpad that help me to understand .
 
Here is the Energia version :
/* PWM * TIMER0 B * PF_1 RED_LED */ #include "inc/hw_memmap.h" #include "driverlib/sysctl.h" #include "driverlib/gpio.h" #include "driverlib/timer.h" unsigned long ulPeriod, dutyCycle; void setup() { ulPeriod = 2000; dutyCycle = 500; // PF_1 on T0CCP1 SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF); GPIOPinConfigure(GPIO_PF1_T0CCP1); GPIOPinTypeTimer(GPIO_PORTF_BASE, GPIO_PIN_1); // Timer configuration SysCtlPeripheralEnable(SYSCTL_PERIPH_TIMER0); TimerConfigure(TIMER0_BASE,TIMER_CFG_SPLIT_PAIR|TIMER_CFG_B_PWM); TimerLoadSet(TIMER0_BASE, TIMER_B, ulPeriod -1); TimerMatchSet(TIMER0_BASE, TIMER_B, dutyCycle); TimerEnable(TIMER0_BASE, TIMER_; } void loop() { TimerMatchSet(TIMER0_BASE, TIMER_B, dutyCycle++); if(dutyCycle >= ulPeriod - 1) dutyCycle = 0; delay(1); } // End of .ino file I wanted to share .. it could be usefull for beginers like me.

Hi Shaun,
 
Nice to read you have it working.
 
May be adding your username to the dialout group could help ... unless you already did that.
 
I have ported TI internal temperature sensor example to Energia and posted it on Energia forum  ... it works ..  nothing spectacular but I am learning and trying to understand step by step.
 
Happy coding
 
Cheers

Hi,
 
I am on Unbuntu 10.04.
 
I created a file in directory :  etc/udev/rules.d  named :   61-stellapad.rules  (Ty Rick)
 
and pasted :
 
SUBSYSTEM=="usb",ATTRS{idVendor}=="1cbe",ATTRS{idP roduct}=="00fd",MODE="0666"
 
save and unplug .. replug Stellaris board.
 
Hope this can help you

Hello,
 
Here is a ino file that allow to display temperature  from LM4F120 internal sensor.
 
It is based on example from TI workbook , ported a la mode Energia.
 
Nothing spectacular. I am slowly learning ARM and I wanted to share.
