I’m trying to get control of motor outputs of the Motorshield DIR A=pin 12 DIR B= pin 13.
#HAS WXTOIMG BEEN FIXED YET SOFTWARE#
Software code: K3NG Rotator Controller from GitHub. (2) Worm-gear motors for Azimuth and Elevation. Hardware: Arduino Mega 2560, Deek-Robot Motorshield R3, Nextion Enhanced 3.2 TFT Screen Here is the project I am currently working on. I added a small fan to the case, to ensure a little bit of air flow over the heat-sink. After days of measurements and oscilloscoping, I found no flyback phenomenon, nothing special. It warms up only when antenna is moving slow (PWM = repetitive MOSFET switching). The MOSFET module (rated 10 times the power) for azimuth PWM failed – replaced. I added the ‘cold switch’ feature in the code. The relay module for azimuth direction (rated 10A) failed – replaced. I added one 5V adaptor for Arduino, LCD, encoders and potentiometers, and another one for relays and MOSFETs. After days of measurements and oscilloscoping, I replaced the 5V adaptor because it had a very big ripple (noise). One 1μF capacitor GND-AzPot on Arduino side lowered the noise to +/- 2º. After adding 12m of LiYCY-12×0.75 cable from controller to rotator, the azimuth reading had a noise of +/- 10 º.

The azimuth motor draws 12V/3A in full power.ġ. I have a home-made DC rotator Az/El 360º/90º. Some afterthoughts after months/years of using this controller and rotator.

Thank you very much to all who sent me feedback, helping to make this project more reliable.Ĭheck the Arduino code page for the codes, drawings and procedures.
#HAS WXTOIMG BEEN FIXED YET UPDATE#
The code has been updated several times, and now, for example, you can set the antenna update in your tracking software, as fast as you want, 0.5 sec. This is necessary if you don’t like the default settings. The motor calibration is only for tuning the Soft-Start / Soft-Stop feature. It ensures correct reading of 0-359 º / 0-90 º, no matter what kind of potentiometer you are using. Once the project is complete and it can move, you must apply the Potentiometer calibration procedure. If you want to give it a try, let me know by email. I have a betaversion with Soft-Start / Soft-Stop for AC motors, taking advantage of this module.īecause I don’t have an AC rotator, I was not able to test it thoroughly in real life. This is the plot of Power output corresponding to Angle error. There’s an adjustable Dead Zone, where the antenna doesn’t move for the slightest target offset. Therefore, when the antenna starts moving, it accelerates progressively, and, when approaching the desired position, it slows down to full stop. It outputs a power response proportional with angle error (TargetAntenna). The DC motors version has the advantage of using PWM for a softer/smoother antenna movement. This is an example of electric diagram for azimuth only. Put A1 to GND to always read 0° elevation.

Just don’t install the parts for elevation. If you only want azimuth control, that’s fine. Jean-Jacques / ON7EQ made a modification to the code for a simple controller -azimuth only- and YAESU communication protocol. Ricardo / CT2GQV, made another version for Linux rotctld and gpredict. And one for 180º elevation, one for 0.1º precision. It can be easily interfaced with commercial rotators. There’s also a variant for AC motors, which offers dry contacts (ON/OFF).
It accepts 0-180º elevation, but rotates the antenna accordingly, for max. PstRotator, WXtrack, HRD, MacDoppler… Even WXtoIMG can control the rotator. This Arduino version is compatible with all tracking software using Eas圜omm protocol / 9600 bauds. Note that so far, PstRotator was the only software who could display the antenna position. There is no fix length, but the decimal is mandatory, even if it is 0. Where the first is the azimuth, then the elevation. The software asks for the current antenna position by sending There is no fix length for the coordinates. In the Easycom2 protocol, the software sends the target position to the controller, like He also generously gave me a license for his software, thank you very much. This version is compatible with EASYCOMM2 antenna protocol.Īfter getting in touch with PstRotator (tracking software) developer, he kindly gave me the solution I was searching for, in order to send back the antenna position to be displayed in the software.
