62. STM32CubeIDE Timer Interrupt with STM32F103C8T6

[@behzodhamrayev_zarband]

I am new in STM32 and I have searched from internet more things This channel was the most helpful. it is really ideal for beginners. Thanks for sharing your experience with the world Nizar. THANKS.

[@NizarMohideen]

Great to hear!

[@candandemircan]

just started getting familiar with embedded software and all the videos on this channel have been so helpful!! easy to understand even for beginners. thank you so much for sharing these!

[@motasee.aliwate7889]

Wonderful video thanks for at all And it's will be so beautiful to explain more about timer ☺

[@NizarMohideen]

Glad you liked it!

[@koggism]

Very well presented and backed up by your website, clear an to the point. Brilliant work

[@yunusyarar8882]

Thank you for very easy and very clever explanations. Excellent!!

[@felipegerber8586]

Thanks a lot for you class! It gonna help me a lot!

[@NizarMohideen]

Glad to hear that!

In prescaler I didnt understood why u put minus 1 after 7200

[@NizarMohideen]

Prescalor starts from 0 (zero) 1 means 0 2 means 1 3 means 2 ..... 7200 means 7199

[@Red_Fang.]

excuse me i want to ask, i want to use timer for my long pressed button, so which function should i use ? thank you

[@busraercan246]

Hİ, when you upload the code , did you use ST-link v2 debugger or usb cable? I couldnt understand that...

[@SauvikRoy]

Nice hands-on video! You have used the timers for GPIO outputs; would it be also possible to use them on inputs?: I was trying to build a software debounce for input switch on my board. Thanks!

[@Oleg-fp9hn]

Hello! Answer please. Can we change timer settings during programm is running? i am considering Car engine manegment system, rotating trigger wheel on crankshaft makes interrupt every 6 degrees. we need to ignite sparks when trigger wheel interrupts + some amount of time. this amount of time alway differ and depends on a lot of parametrs.

[@NizarMohideen]

Yes. You can HAL_TIM_Base_Stop_IT(&htim2); // During prorram running change the values inside MX_TIM2_Init() MX_TIM2_Init(); HAL_TIM_Base_Start_IT(&htim2);

[@Oleg-fp9hn]

@@NizarMohideen thank you, awesome. i will try it.

[@giupeppe6380]

hi, very helpful video. I have to program a counter, using internal timer, which counts in steps of 100 nanoseconds. i think i need at least 10mhz, the bluepill has 72mhz so i should be ok, but i am scared about crystal/ceramic resonator that is 8mhz. The counter starts when a photodiode change is value. what do you think? thanks and have a good day

[@АндрейКим-ж1р]

This is really cool ^_^

[@NizarMohideen]

Thanks

[@ovaisiq]

Thanks Sir

[@hanifsowlatnia9822]

Nice

[@bandulamanchanayaka4971]

can I use the defoult high speed clock and adjust the counture peroid,and pre scaler

[@NizarMohideen]

Yes. You can Adjust the prescalor and counter period according to the required interrupt time

[@bandulamanchanayaka4971]

thanks, I connect the TCS34725 colour sensor int pin to GPIO to get timer intepurret data. how can check getting data in right time intervals

[@NizarMohideen]

// Have any variable such as xyz // in the interrupt callback routine set xyz to 1 void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim){ if(htim->Instance == TIM2) { xyz=1; } } // In the while loop If (xyz==1) { getRGB(&red, &green, &blue); xyz=0; }

[@bandulamanchanayaka4971]

Thanks, if I need to get 10 sample in same timer,how can i do can I change the xyz value 1 to 10?

[@majesty-4246]

How to make all of the project will be off after 5 minutes on?

[@satishpatidar4756]

How to dynamic value at runtime it means change time

[@NizarMohideen]

To set Prescaler at runtime __HAL_TIM_SET_PRESCALER(__HANDLE__, __PRESC__); Example : __HAL_TIM_SET_PRESCALER(&htim2,7200); To set Counter Period at runtime __HAL_TIM_SET_AUTORELOAD(__HANDLE__, __AUTORELOAD__) Example : __HAL_TIM_SET_AUTORELOAD(&htim2, 2000);

[@vidyadharisakala2204]

Can you tell me how did we get 2000 for 200 milliseconds

[@midhunkarthi6038]

How can I set an interrupt for 5 minutes?

[@reisaaurellia5839]

Thankyou in advance because of all your video really help me,,, May I request for the next video?? I want to know how to smart water meter with LoRa and Get the Data in server Thankyou

[@NizarMohideen]

Thanks. I will try one at time.

[@Ngigi]

Did you use a hardware debugger?

[@Ngigi]

I'd like to know if I can program this board without the st-link debugger

[@NizarMohideen]

Yes. You can use FTDI. But, it will not work with CubeIDE. You can use STM32 via FTDI using other IDE's for example ArduinoIDE. I have seen there are many videos available in the youtube.

[@Ngigi]

Thank you,I have used Arduino IDE before.Thought I could use the FTDI with CubeMX..thanks for assisting.

[@makergaragediy]

Could explain how make pwm with variable frequency to control nema17 speed?

[@NizarMohideen]

I am sorry I don't have nema17 with me at the moment

[@TheRecocebo]

can we write 7199 instead of 7200-1

[@NizarMohideen]

Yes. You can
