regarding PWM

You can refer to the register settings in CC253x/4x User's Guide and do some test to control the duty cycle.

hi sir !! 

the link is not opening sir !! !

I fix the link.

hi sir ... the code you send when i ran it it is not giving any wave in the cro ... i checked it in the pin 14 on the dk kit sir 

i got the pulse value sir !! 

hi sir !!! 

the code is running but there is a small delay in the pulse .. like glitches where should i use the timer pgm 2 get a continuous pulse sir .. i mean should i declare it as an separate event ?? 

What do you mean "small delay in the pulse"? DO you have a scree capture of your PWM output?

i saw the doccument sir ,, bt couldnt get that much idea sir , 

how to use the digital data from 20 t0 30 to change the duty cycle of the pwm and control the speed of a motor or intensity of the light 

Your PWM signal is incorrect. Please check your HW. Do you measure correct on P1.4?

THE screen short i send is by taking from the port P1_0 which is mapped to pin 6 .

the pin P1.4 is mapped to pin 14 and it is not at all giving any outouts sir 

My example code is to output PWM to P0.4. Please make sure your measurement is on P0.4.

the pin p0.4 is not giving any waves sir , in P1 SMD_SOCKET_2X10 pin p0.4 is maped to pin 3 which is not giving any waves sir ... i also declared the pgm as an additional event in my pgm ..it is giving a single wave in the pin p1.0 1ly sir (the screen shot i send you) . how to get the correct waveform sir whose dutycycle can be manipulaed according to the data i got . 

how can i write the timer code in the sampletemperature sensor pgm sir ?? is there any way i can do like that , i tried like this 

if ( events & SAMPLETEMPERATURESENSOR_TIMER_EVT )
{  PERCFG &= (~(0x20)); // Select Timer 3 Alternative 1 location
  P2SEL |=0x20;
  P2DIR |= 0xC0;  // Give priority to Timer 1 channel2-3
  P1SEL |= BV(4);  // Set P1_0 to peripheral, Timer 1,channel 2
  P1DIR |= BV(4);

  T3CTL &= ~0x10;             // Stop timer 3 (if it was running)
  T3CTL |= 0x04;              // Clear timer 3
  T3CTL &= ~0x08;             // Disable Timer 3 overflow interrupts
  T3CTL |= 0x03;              // Timer 3 mode = 3 - Up/Down

  T3CCTL1 &= ~0x40;           // Disable channel 0 interrupts
  T3CCTL1 |= 0x04;            // Ch0 mode = compare
  T3CCTL1 |= 0x10;            // Ch0 output compare mode = toggle on compare

  T3CTL &= ~0xE0;   // Clear Prescaler divider value
  T3CTL |= 0xA0;    //Set Prescaler divider value = Tick frequency /32
  T3CC0 = 128;      //Set ticks = 128

  // Start timer
  T3CTL |= 0x10;

return ( events ^ SAMPLETEMPERATURESENSOR_TIMER_EVT );
}

and i defined SAMPLETEMPERATURESENSOR_TIMER_EVT as 0x0001

i also tried keeping the pgm in other function also , but not working sir 

the code is rite sir but i think it is not executing properly !!!!!!without the code also i am getting the same signal as in the output sir 

P1.4 of CC2530 is connected to P1 pin23 on SmartRF05EB. Please try to measure P1 pin3 on SmartRF05EB for PWM signal first.

yes sir i found the pin . but the signal is not at all comming sir .. .is the way i used the coding in my pgm right , thats the biggest doubt sir

Do you use osal_start_timerEX to start SAMPLETEMPERATURESENSOR_TIMER_EVT event?

yes sir i did like this also 

osal_start_timerEx( zclSampleTemperatureSensor_TaskID, SAMPLETEMPERATURESENSOR_TIMER_EVT, SAMPLETEMPERATURESENSOR_REPORT_INTERVAL );

in the event of SAMPLETEMPERATURESENSOR_TIMER_EVT .. yet no out put sir 

sir 

is there anything else i need to do inorder to set timer in my sample temperature sensor pgm???

Can you take a picture that how you connect P1.4 to see PWM on scope?

of course i will sir ,..

i connected the ground of the cro to ground of the debug pin and 

the other terminal of the cro to the pin 3

HI SIR ACCORDING TO THIS DOCCUMENT IT IS IN 14TH PIN SIR .. IS IT 14 OR 23 ??? 

The attached schematic is for CC2530EMK. What I say P1 Pin23 is on SmartRF05EB.

VERY SORRY SIR ... i got the output sir !! 

i got the wave as above sir ... but there is a delay , is it in the timer pgm or in the event i declared the timer code sir ??

can u pl tell me how to control the duty cycle using the digital data i have  ??? 

Please read register definition for T3CC0, T3CTL, and T3CCTL0 in CC2530 user's guide and change accordingly to change duty cycle.

okey sir but the delay in thee picture is due to what pblm sir ??

 is it in the timer pgm or in the event i declared the timer code sir ??

can u pl tell me how to control the duty cycle using the digital data i have  ??? 

1. I suppose the delay is caused by your timer event. You should check it. PWM is a HW signal and it only need to start once.

2. Please read the user guide and try to change duty cycle first. However, I have no idea how to mapping your digital value to PWM duty cycle. It is application related and you suppose to find out by yourself on your HW.

sir 

CAN YOU PL HELP TO ELIMINATE THE DELAY ALONE SIR .. I TRIED ... DUTY CYCLE I THINK I CAN GET SIR

Try not use event to start PWM. You can put PWM code in "if ( keys & HAL_KEY_SW_4 )" and use SW4 to trigger it.

tried it sir but the delay is still comming the same delay 

is there any way to change the dutycycle sir ?? ?

i mean which registers should i use to change the duty cycle ??? 

HI SIR !

 i found the following code !! 

PERCFG &= ~0X40 ;  set timer alternative 1 location
P2DIR = (P2DIR & ~0XC0)| 0X80 ; give priority to timer 1

P0SEL |= 0X08 ; set P0.3 to pheripheral 
T1CC0L = 0XFF ; pwm signal period
T1CC0H = 0X7F ;
T1CC1L = 0X78; pwm duty cycle
T1CC1H = 0X10;
T1CCTL1 = 0X1C ;
T1CTL |= 0X0F ; divide with 128 and do up-down mode

could you please tell me in which pin of the cc2530 kit will the output wave of the pin is mapped sir

thanks sir !! i got it 

hi sir 

PERCFG &= ~0X40 ;  set timer alternative 1 location
P2DIR = (P2DIR & ~0XC0)| 0X80 ; give priority to timer 1

P0SEL |= 0X08 ; set P0.3 to pheripheral 
T1CC0L = 0XFF ; pwm signal period
T1CC0H = 0X7F ;
T1CC1L = 0X78; pwm duty cycle
T1CC1H = 0X10;
T1CCTL1 = 0X1C ;
T1CTL |= 0X0F ; divide with 128 and do up-down mode

in this pgm how can i change the duty cycle sir ?? 

Don't you say you get it? What is your problem?

Yes SIR !!

when i change the values of t1cc1l and t1cc1h the waves are changing but i couldnt get the fact that how the wave is changing and all .. i thought that i can use the register t1cc1 16 bit register bt i dont think it will work sir ..

any suggestions  

sorry for bothering you sir ,

i found it , thanks 

Not at all. I am glad you find it out. Maybe you can share your finding to benefit others.

sure sir !!!! 

hi sir !! 

i actually used the timer code like 

if ( events & SAMPLETEMPERATURESENSOR_TIMER_EVT )
{
zcldata = (int8) zclvalue ;
PERCFG &= ~0X40 ;
P2DIR = (P2DIR & ~0XC0)| 0X80 ;
P0SEL |= 0X08 ;
T1CC0L = 0XFF ;
T1CC0H = 0X7F ;
T1CC1L = 0x78 ;
T1CC1H = zcldata ;
//T1CC1 = 25 ;
T1CCTL1 = 0X1C ;
T1CTL |= 0X0F ;

osal_start_timerEx( zclSampleTemperatureSensor_TaskID, SAMPLETEMPERATURESENSOR_TIMER_EVT, SAMPLETEMPERATURESENSOR_TIMER_INTERVAL );

return ( events ^ SAMPLETEMPERATURESENSOR_TIMER_EVT );
}

and the Zzcldata will be updated by using the values from the ZC

static void zclSampleTemperatureSensor_ProcessInReportCmd( zclIncomingMsg_t *pInMsg )
{
char str[8];
zclReportCmd_t *pInTempSensorReport;
zclReportCmd_t *pOutDemandReport;
uint8 outDemandBuffer[sizeof( zclReportCmd_t ) + ( 2 * sizeof( zclReport_t ) )];
// bool send = TRUE;

pInTempSensorReport = (zclReportCmd_t *)pInMsg->attrCmd;

if ( pInTempSensorReport->attrList[0].attrID != ATTRID_MS_TEMPERATURE_MEASURED_VALUE )
{
return;
}
//srcAddr=pInMsg->srcAddr;
// endPoint=pInMsg->endPoint;

pOutDemandReport = (zclReportCmd_t *)outDemandBuffer;

// store the current temperature value sent over the air from temperature sensor
zclvalue = BUILD_UINT16(pInTempSensorReport->attrList[0].attrData[0], pInTempSensorReport->attrList[0].attrData[1]);
if (zclvalue)
{

HalLedSet ( HAL_LED_2, HAL_LED_MODE_ON );
sprintf(str, "%dC", ((uint8)zclvalue));

HalLcdWriteString(str, HAL_LCD_LINE_3);

}

else

{

HalLedSet ( HAL_LED_2, HAL_LED_MODE_OFF );
sprintf(str, "%dC", NULL);

HalLcdWriteString(str, HAL_LCD_LINE_3);

}

zcl values will be updated in this function ... what am i doing wrong sir

What is your problem and what do you intend to do?

by changing the values in the register T1CC1H i can change the value of the duty cycle of the generated pwm sir ... so 1ly i wrote in the event function as T1CC1H = zcldata and i saved the 16 bit value in zclvalue in the zcldata as 8bit value ...

but when i run the pgm the pulse is not at all varying as i intended sir 

Are you sure that your zclvalue really changes?

yes sir it is changing and i am viewing the change in the lcd using the lines 

if (zclvalue)
{
//zcldata = (int8)zclvalue ;
//T1CC1H = zcldata ;
HalLedSet ( HAL_LED_2, HAL_LED_MODE_ON );
sprintf(str, "%dC", ((uint8)zclvalue));
HalLcdWriteString(str, HAL_LCD_LINE_3);

}

You only map zcldata to T1CC1H and I suggest you to check if it is large enough for duty cycle change.

yes sir ,

when i write like T1CC1H = 80 or any other values the pwm wave with different dutycycle can be obtained without any pblms sir .

but when i map like T1CC1H = zcldata it is not at all working even if the zcl data value is changing

hi sir !! 

why is the register not updated by the values ,, any comments ??

Your zclValue is uint16 but the register is byte size. You should check if it is truncate.
