Timer1 PWM Servo Control 🔴 ATmega328P Programming #15 AVR microcontroller with Atmel Studio

[@Lucas-pj9ns]

thanks for the clear video love how you explained the datasheet instead of saying just look at the datasheet

[@phoemur]

That's awesome. Learned a lot from these tutorials. Good Job. Waiting for the next ones

[@West-rq3lu]

Keep up the good work man

[@vaibhavwanere3034]

Great Work! Thank you so much.

[@9700784176]

Thanks!

[@BinderTronics]

Truly appreciated

[@pauseandlearn8626]

thank you so much. Could you please add English subtitles if possible? I am so looking forward to the next lecture. Please continue teaching.

[@BinderTronics]

The automated English subtitles are on and are ferly accurate. It is extremely time consuming to write transcripts. It can take up to 16 hours for a 10min video. I have look into methods to outsource transcripts in a trust worthy manor or I cannot justify the cost.

27:32 realiza este cambio //#define SERVO_MIN (1999u) #define SERVO_MIN (999u) Te funcionará con el recorrido completo

[@BinderTronics]

Es un servo de 135 grados. Mató a muchos antes de descubrirlo. Mismo proveedor. Mismo producto. Etiqueta incorrecta. It is a 135 degree servo. Killed many before finding that out. Same supplier. Same product. Wrong label.

[@WhatTheFuckII2oV3]

Maybe you can help me. How do you turn OFF FastPWM AFTER initializing/starting the signal? I was thinking about TIMSK1 &= ~(1

[@BinderTronics]

You want stop the clock of the timer to stop PWM. TCCR1B &= (0b000

[@BinderTronics]

or change the mode of TCCR1A in the WGM1x bits

if there is no pickit, how to program ATMEGA?

[@BinderTronics]

you don't have a pickit or the pickit is not showing up in the ide?

[@fisikamodern5209]

@@BinderTronics I don't have pickit

[@BinderTronics]

ISP programmers. Cheap is something that emulates a stk500. Other options are Atmel ice and Mplab snap. You can also use a Arduino UNO but I have no idea if it will work with Atmel Studio. If you are really lucky you can find someone selling a original avrisp mkii.

How can i program multiple servos Simultaneously No one showed this.

[@BinderTronics]

PWM channel per servo. This chip has 4 channels. If you need more use something like a PCA9685.

[@9700784176]

20:06 you created a function, pwm_sweep(void). and you have not used that function in the main.c, what is the purpose of creating that function?

[@BinderTronics]

19:00 quality of life function. It is for testing.

[@9700784176]

@@BinderTronics sorry for storming with my doubts. could you please reply in brief, what do you mean by "quality of life function", and how did that function helped/used in testing. I even searched in google, WHAT IS QUALITY OF LIFE FUNCTION, to my dismay, I found nothing. Actually, I'm new to microcontrollers and also to programming. fortunately, I found this video helpful.

[@BinderTronics]

Quality of life function is my term for it. I use the term mostly for debug functions. The function is identical in function to the main loop just without the conversion from degrees. It allows the user to easily tweak the the min and max range of the servo macros and test if the code is controlling the servo as expected. Once the servo is confirmed to work then the servo_set() function was developed. It comes down to the fundamental of breaking down code into sections and testing bit by bit. Code -> Test -> Debug -> Return to start. I recommend you start using the simulator and start picking the code apart yourself. You will gain much more from it than me explaining it to you. kzbin.info/www/bejne/iHeXXoF4bJxpqNE

19:00 how this while loop work. as this got no curly braces while(update_pwm_ready != 0); OCR1AH = (i & 0xFF00) >> 8; OCR1AL = (i & 0x00FF); can anyone pls explain. thanks in advance

[@BinderTronics]

Infinite loop until the condition is not met. You do not need to put anything in the loop. Thus no {}. while(1); for( ; update_pwm_ready != 0 ; ); if(1); All valid syntax.

[@9700784176]

@@BinderTronics Thanks for the reply after some google... I found, without braces, only the first statement will run in infinite loop. here, in the code while(update_pwm_ready != 0); OCR1AH = (i & 0xFF00) >> 8; OCR1AL = (i & 0x00FF); the first statement is OCR1AH = (i & 0xFF00) >> 8; when, OCR1AH and OCR1AL, belong to the same register OCR1A. what is the point of running only one half of the register, infinite times.

[@BinderTronics]

This is what you are looking at. while(update_pwm_ready != 0) { }; OCR1AH = (i & 0xFF00) >> 8; OCR1AL = (i & 0x00FF); This does not run in the loop (i & 0xFF00) >> 8 This will do what you are describing. while(update_pwm_ready != 0) OCR1AH = (i & 0xFF00) >> 8; Note the missing ; after the while.

10/10 for program, 1/10 for representation, people who already don't know what you are talking about can't understand you.

[@BinderTronics]

That's why there is a playlist that takes it from the ground up. I only assume knowledge of C.

[@markvolf3531]

@@BinderTronics Ok, btw I managed to figure it, thanks for the Help, without it I wouldn't make it. Just try to code a little bit slower. +where can I install Atmel studio?

Might want to try Microchip Studio. Atmel studio got renamed. Full playlist on the ATmega328p kzbin.info/aero/PLtuqBdbsL-DvbB6QAGgoGBAEsGuXfGFoF
