The following post offers pic Assembly for both a four servo and an eight servo pic based Controller: pic Based Serial Port servo Controller The design uses a pic16F84, however porting it to a pic16F877 should not be too much of an issue. The following (...)
Is it true that adding one more data byte stops USB device operation? I rather guess it's the call to commandservoToAngle1(), that further increases software latency and possibly exceeds the maximum allowed delay to service the USB. The delay loops are a "rusty" method to generate servo pulses, you should better think of a solution based on har
Hello everybody I'm facing with a problem in my H bridge design. I am using pic 18F45K20 Microchip Controller along with BJT tranzistors to make a servo direction for a 5V motor. Everything is fine but i can't get around with C code for microcontroller. I'm using C18 Compiler. I want to get the signal from a switch on the development

Hi, I am pretty new on this forum. I have a background on coding with pic and MATLAB. As of now, I have developed codes for object detection and tracking in MATLAB. My code detects a red object in an image/video and gives its centroid location. The red object is then tracked also as it moves. However, I am getting absolutely no clue as to how to
What you need to remember is A servo requires a cycle of about 20ms The position of the arm (on most servos) is a pulse between 1ms & 2ms, wth 1.5ms being the centre. Therefore as an example to move the arm to an extreme High pulse 2ms low for 18ms- making the 20ms cycle. This needs to be continously repeated to hold the arm in the correct positi

I wanna use bluetooth module and servo on proteus and then rotate the servo clockwise/counterclockwise controlled by a switch in proteus. The switch would only represent the position of the servo, high or low, depends. is this possible? Any source code for this? I don't know what kind of Bluetooth to use as well as the pic i (...)
Hi, I need to interface a potentiometer with a servo motor via the PWM module of pic 18F4550 using mikroC. Can it be done? If so, please help me out. Thanks in advance. servo motor needs 50Hz PWM. What I know, pic16 PWM Module can't generate low frequency at 50Hz. I don't know how pic18. The option is (...)
To genarate pulse for servo, need PWM at 50Hz. pic16 can't use PWM module. Use delay function also, not good for many servo. Other way, you can generate PWM using Timer Interrupt. See example servo. or You can use servo Controller that use UART to set servo position like this product, [URL="ht
What is your clock frequency of dspic30F? Most RC servos require a PWM period of 20ms and a duty cycle of 1ms to 2ms depending on the required position of the servo. How to Interface a Microchip pic MCU with a hobby R/C servo Such low frequency PWM is difficult to achiev
Most, but not all, RC servos have a rotation range of +/- 90°. You can control the position of a servo by varying the duty cycle of the PWM. The period of your PWM should typicaly be 20ms or 50 pulses per second, with the ON time of the PWM set at between 0.9ms to 2.1ms. Each servo is different so these are just (...)

Hi, i'm trying to control a servo Futaba S3003 using a pic, i've been searching lot of information on how doing it, the thing is that it looks very simple but it just doesn't work and i can't figure why. I wrote the easyest code to make the servo spin right, left, and go to the center but it just turns to the right. I've tried all the (...)
that is about controlling a servo with serial port to MCU right?. would that be the same if i would connect it directly to my pic? Hi, On that example, which is nearly 10 years old, you need some method of tellling the motors what to do, rather than use control keys on the pic they use the serial port of th
Hi, There are loads of googled Tutorials and examples for servo motors out there - here is just two -
Hi I do not program in C, but I do work with RC and servos. Most servos have range of control from 1ms to 2ms with 1.5ms being the middle settings. (some can operate slightly outside these ranges). I would say that your range of 2500us could be outside the scope of the servo. They normally have a complete cycle of 20ms (include PPM (...)
I have a servo motor and a pic controller connected to the serial port of my PC. It's working fine. When I order my servo to move from 30 deg to 60 deg. It's good BUT, when I order my servo to move from 30 deg to 70 deg. It turns back to 0 deg then goes to 70 deg. Why is it happening? I don't want my (...)

Now i need your help with the (...)
Hi, It depends on exactly what you are trying to do and what type of motor you are trying to control ? - dc brush motor, stepper, servo etc. Each type of motor needs a different method of control from the pic - which one are you using ? You can change direction of a dc brush motor just by changing the state of a double pole relay with th
Hi fellows; I have a question and I appreciate that if somebody give me an proper answer! I intend to control a standard servo motor with PWM output of a pic16F887 which its period is 20 ms! By application of timer 2 prescalar I can generate the PWM signal on PWM outputs with maximum of 4ms period, while the servo needs 20 ms period! (...)
I have not designed on atmel before, only on pic series. How much code have you designed yet, have you developed the hardware. I am sure you would have worked out the ADC control modules (to receive analogue data). Is there any feedback generated by the servo?? thanks aa
Just allow usage of all io pins, and duplicate spi, twi ports as much as you need. Most of the sensors can be found with i2c interface. Also with serial interface you can comunicate with other pcbs. In my design i use as much dedicated (servo) systems, so if main pcb is jammed, system can survive ...
