I don't think there is a specific reason for that exact angle. Mainly you want to be sure the photodiode and LED are not in direct view of each other.

Forum Post: CCS / CC2650： An attempt to connect to the XDS110 failed
Part Number: CC2650 Tool/software: Code Composer Studio I am trying to run the hello world code on my board. I see in the Console: Cortex_M3_0: GEL Output: Memory Map Initialization Complete. Cortex_M3_0: Failed Board Reset: (Error -260 @ 0x0) An attempt to connect to the XDS110 failed.

Part Number: MSP432P401R Tool/software: Code Composer Studio Hello all members of TI forum! I use the example code that called timer_a_pwm_code to control the brightness of LED. The code I had modified as following: /* DriverLib Includes */ #include /* Standard Includes */ #include #include //![Simple Timer_A Config] /* Timer_A PWM Configuration Parameter */ Timer_A_PWMConfig pwmConfig = { TIMER_A_CLOCKSOURCE_SMCLK, TIMER_A_CLOCKSOURCE_DIVIDER_1, 1920, TIMER_A_CAPTURECOMPARE_REGISTER_1, TIMER_A_OUTPUTMODE_RESET_SET, 192 }; //![Simple Timer_A Config] int main(void) { /* Halting the watchdog */ MAP_WDT_A_holdTimer(); //![Simple Timer_A Example] /* Setting MCLK to REFO at 128Khz for LF mode * Setting SMCLK to 64Khz */ MAP_CS_setReferenceOscillatorFrequency(CS_REFO_128KHZ); MAP_CS_initClockSignal(CS_MCLK, CS_REFOCLK_SELECT, CS_CLOCK_DIVIDER_1); MAP_CS_initClockSignal(CS_SMCLK, CS_REFOCLK_SELECT, CS_CLOCK_DIVIDER_2); MAP_PCM_setPowerState(PCM_AM_LF_VCORE0); /* Configuring GPIO2.4 as peripheral output for PWM and P1.4 for button * interrupt */ MAP_GPIO_setAsPeripheralModuleFunctionOutputPin(GPIO_PORT_P2, GPIO_PIN4, GPIO_PRIMARY_MODULE_FUNCTION); MAP_GPIO_setAsInputPinWithPullUpResistor(GPIO_PORT_P1, GPIO_PIN4); MAP_GPIO_clearInterruptFlag(GPIO_PORT_P1, GPIO_PIN4); MAP_GPIO_enableInterrupt(GPIO_PORT_P1, GPIO_PIN4); /* Configuring Timer_A to have a period of approximately 30ms and * an initial duty cycle of 10% of that (192 ticks) */ MAP_Timer_A_generatePWM(TIMER_A0_BASE, &pwmConfig); //![Simple Timer_A Example] /* Enabling interrupts and starting the watchdog timer */ MAP_Interrupt_enableInterrupt(INT_PORT1); MAP_Interrupt_enableSleepOnIsrExit(); MAP_Interrupt_enableMaster(); /* Sleeping when not in use */ while (1) { MAP_PCM_gotoLPM0(); } } /* Port1 ISR - This ISR will progressively step up the duty cycle of the PWM * on a button press */ void PORT1_IRQHandler(void) { uint32_t status = MAP_GPIO_getEnabledInterruptStatus(GPIO_PORT_P1); MAP_GPIO_clearInterruptFlag(GPIO_PORT_P1, status); if (status & GPIO_PIN4) { if(pwmConfig.dutyCycle == 1920) pwmConfig.dutyCycle = 192; else pwmConfig.dutyCycle += 192; MAP_Timer_A_generatePWM(TIMER_A0_BASE, &pwmConfig); } } I change the period and the duty cycle, but it did not occur variation of brightness when I connect the MSP432P401R Launchpad to the LED which on the breadboard. I connect the PWM signaloutpin2.4 as VCC on breadboard to LED and the GND pin as GND on breadboard to LED. I find when I change the period, I only change the blinking frequency of LED. I press the button pin1.4 can not obtain the brightness variation. I have get no ideas. Can somebody give me a advice of code or an example code of PWM? I appreciate any help. Sincerely thanks!

Forum Post: Why do the output of the bridge rectifier at the output of the Push pull transformer shoots to more than 1KV when a series L is connected as a filter?
Hai, I am designing a Solar inverter with pushpull topology on the primary side.my transformer is designed to generate a peak voltage of 400V at secondary.I actually placed bridge at the output of the transformer and found pulsating DC at the output of the Rectifier which is of 400V.But when i connect a LC Filter i happen to see that the Voltage shoots to KV range(across recifier).Why is that so? Should i redesign my induct or value? How should i go about designing a induct or for a push pull transformer?I have designed it for an output of 5A.
