Hello all,
My question again. I'm trying to make a two-way camera Gimbal. I have modified working programs. The transmitter now has two ADC inputs and the receiver must control two servos. The signals arrive correctly at the receiver in fits and starts. I can't get the servos to work. Attached are the two files.
Please respond again,
regards
Hans

Sorry,Ā I used a wrong expression, Gimbal is something different. I just want to pan and tilt a camera wirelessly

Hi Hans,
I cannot see any errors. So the data is received correctly but the servo's do not work?
Have you tried to get the servo's working without the receive routines? So just hard-code some values to see if the servo's are working?
Kind regards,
Rob

Hi Rob,
If I add this before the original forever loop then just servo 2 moves. Changed servo's same result
forever loop
servo_move(60,1)
servo_move(60,2)
delay_1S(2)
servo_move(150,1)
servo_move(150,2)
delay_1S(2)
Ā end loop
servo_move(60,1)
servo_move(60,2)
delay_1S(2)
servo_move(150,1)
servo_move(150,2)
delay_1S(2)
Ā end loop

Hi Hans,
The only difference that I see is the looptime.
Ā Instead of 1 second it is 1 ms but it depends on how fast the data is received. If that is too fast will that disturb the servo movement?
Kind regards,
Rob

I have now adapted both circuits for WiFi. (So the transmitter has a WiFi master and the receiver a slave)
Ā The data received is identical to the transmitter
. However, the servos only move half a turn. Apparently the Servo-lib can't handle the pic. Or I have to set something else. The programs are attached again.

Hi Hans,
Servo's move depending on the PWM signal sent to them. It is possible your servo's are expecting a different signal depending on the manufacturer. Do you have other servo's to test?
Do your servo's work correctly an un-modified Jallib sample?
Do you have an oscilloscope you can test the signal with? The PWM signal should be between 0.5ms and 2.5ms.
Thanks,
Matt.

Hi Mathew,
I've used your lib dozens of times on all kinds of servos and they always worked perfectly!!!! These servos also work on the special tester that also works on your lib. I'm pretty sure there is a conflict with the PIC here. If I now go from 0 to max with the potentiometer, the servo only moves half a turn. I just don't know what part of the frequency range they get.
In any case, very nice that you responded.
regards
Hans

Check your clock frequency. If it is half what it is supposed to be your servo's would only get half pulses and half movement.
Not sure if it helps here but I suggest you try the slip library sometime for sending data packets. See samplesĀ 18f4620_slip_isr.jal orĀ 18f4620_slip_poll.jal.

Hello Matthew,
More than 10 years ago I made Marieke with your lib, 8 servos and a very expensive wireless command set
. (see https://youtu.be/U3uuH1cK8Dk)
Ā Ā I used a 16F1827 as transmitter and a 16F648a as receiver. I am now trying to use this old set for this, but as always my old programs no longer work in the changed JAL world. Time and again I experience that a sample only works in that sample environment and as soon as I want to use another PIC I have to complain to you. For me, electronics is still a tool to achieve something and not a goal in itself.
I'll see what I can do with your advice,
Thank you
Hans

Hello Rob,
I have killed one of my 16F15325, is it possible to use the16F1455 for thisĀ nrf24101 project? I have two of them.

Hi Hans,
I think you can. Is has sufficient ROM and RAM and a SPI interface.
Kind regards,
Rob

Hello Rob,
I don't think it will work. I need two ad inputs and pin_A2 is Vusb. I also don't understand why the programming pins are C0 and C1 instead of A0 and A1.

Hi Hans,
The reason that they re-assigned the programming pins - I think - is because the 'original' programming pins are also the USB pins. For debugging it is much more convenient that you can both use the programmer and the USB port at the same time.
For example if you use an 18f14k50 you are constantly disconnecting the USB port when programming the device. Very unhandy.
You asked if it worked for an NRF24L01 and that it the case š.
It will work with any other PIC as long it has sufficient ROM and RAM.
Kind regards,
Rob

Hello Rob,
For data transmission your lib works fine. I was not able to solve the collaboration with the servo lib.
I borrowed a pic from my wind meter that also works fine with this. I now control the camera servos with an extra PIC. This headache file can now be closed.
regards
Hans
