#18645 Initializing Brushless Motor problem

Posted by Vallekano on 01 October 2011 - 01:38 PM in Netduino 2 (and Netduino 1)

Could do better with thyristors? The engines go directly to the 11.1 V battery and I think that each engine at full power consumes about 16 A Which of these would be nice? http://www.micropik....g_ci_triacs.htm



#18641 Initializing Brushless Motor problem

Posted by Vallekano on 01 October 2011 - 09:15 AM in Netduino 2 (and Netduino 1)

After holidays and other things yesterday I tried again yesterday. I tested with a pull-up and Pull-Down but got nothing. I want to try the solution of a relay. The scheme I think I have clear (which is attached). - Would have a switch that would do is control the supply circuit of Netduino. - The program would start and once the program is initialized activate the digital output that in turn activate the relay, closing the supply circuit of ESC. Well, I think this is simple. My problem is that I have begun to look relays and i don't know what I need. The ESC's that I have are 18 A each. Ideally, a relay to feed the 4 ESC's that I have. I've been looking relays and I find specifications such as: - Relay coil 12V CC, 6A 250V CA/30V CC - Relay coil 12V CC, 1A 220V - Signal relay 5V G5V-1, 24V G5V-1 - ... Come on, I have no idea that specifications must have the relay I need. - When talking about going to 12V, 5V or refers to is the voltage at which "closes" the relay? - Puts the maximum power for AC. How is DC? I'm afraid to put a hold not need as many as possible amperior 4 ESC's Thank you. (translated with google, sorry)



#16025 Initializing Brushless Motor problem

Thank you very much everyone. I'll try it from the pull-up resistance (when I return from vacation) I think the easiest option.



#15923 Initializing Brushless Motor problem

Posted by Vallekano on 26 July 2011 - 02:59 PM in Netduino 2 (and Netduino 1)

Hello, I hope you can help me. I'm using Google translator, I do not speak good English. I'm doing a quadcopter and there is something I do not understand. I used a library to control servos and have it modified to run the motor with ESC. The problem is as follows: - If I connect the Netduino and then connect the ESC to the battery everything works fine. - But if I connect two devices at once from the beginning, the ESC does not start well. Does not beep it is connected. Must always be the Netduino already connected before power is applied to the ESC. This is correct and should control it with a relay or something that escapes me.



#10648 Read PPM signals

I posted a class I wrote to read signals from an RC receiver in this thread:

it works !!

Trank you very much



#10582 Read PPM signals

Posted by Vallekano on 05 March 2011 - 10:13 AM in Netduino 2 (and Netduino 1)

Hello, The first thing to say is that I do not speak English and I apologize for my bad English. I would like to use an RC transmitter to interact with the Netduino like this: http://blog.bricogee...pm-con-arduino/ http://sites.google....do-del-receptor I've seen this post: http://www.arduino.c...?num=1199165055 But I think I can not read the PPM signal with Netduino API. I've seen here talking to simulate the "PulseIn" http://forums.netdui...sensor/&.google Could connect an RC transmitter in our Netduino? Thanks
