Hey ! We want to do the same thing with a french team. May it be posible for you please to answer a few questions ? First where did you find your magnets and what is their reference ? What is their shape ? Are you using an halbach array ? If you do so what is the gap between the magnets ? Thank you very much for your time and attention !
Hi the teensy 3.1 has a CAN controller, you need a CAN transceiver like MCP2551 to connect. Basically the transceiver is the physic layer of the CAN bus and the CAN controller of the teensy interprete the data from the transceiver. Hope it's clear! (I may have done english mistakes sorry I'm french ;) )
Thanks for sharing this but can you list what are the exact resistors value, and how wires are connected please. i have been trying to get canbus working for the past 3 weeks never got a good luck.
Since Andy invited us to take a look at his code, I’ve taken the liberty to transcribe it from screen shots of his RU-vid Teensy CAN Bus Testing video. Although, the two sketches complied and uploaded okay to a Teensy 3.6, the Receiver serial monitor remains blank. Maybe somebody with sharper eyes than mine, can review the transcribed code and detect any errors in my work. Hopefully Andy will see this posting and review the code as well. // DMK 09-02-2017 Teensy 3.6 Receiver // Andy Woerpel Teensy CAN-Bus Code // ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yQpfbf48dPQ.html // Receive (Teensy 3.6, Arduino IDE 1.8.4, Teensyduino 1.38 with SN65HVD230 Transceiver) #include <FlexCAN.h> #include <kinetis_flexcan.h> const int baudRate = 50000; const int ledPin = 13; const int delayTime = 1000; int count = 0; FlexCAN myCAN(baudRate); CAN_message_t message; CAN_message_t rxmsg; void setup() { pinMode(ledPin,OUTPUT); Serial.begin(115200); // Modified DMK 09-04-2017 digitalWrite(ledPin,HIGH); myCAN.begin(); } void loop() { if (myCAN.available()) { myCAN.read(rxmsg); Serial.println(rxmsg.buf[0]); if (rxmsg.buf[0] == 49) { Serial.println("Message Sent"); message.buf[0] = count; message.buf[1] = count + 1; message.len = 2; message.id =0x2; myCAN.write(message); count++; } } } // DMK 09-04-2017 Teensy 3.6 Transmitter // Andy Woerpel Teensy CAN-Bus Code // ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yQpfbf48dPQ.html // Transmit (Teensy 3.6, Arduino IDE 1.8.4, Teensyduino 1.38 with SN65HVD230 Transceiver) #include <FlexCAN.h> #include <kinetis_flexcan.h> const int baudRate = 50000; const int ledPin = 13; const int delayTime = 50; FlexCAN myCAN(baudRate); CAN_message_t message; CAN_message_t rxmsg; void setup() { pinMode(ledPin,OUTPUT); Serial.begin(115200); // Modified DMK 09-04-2017 myCAN.begin(); } void loop() { for (int i = 1; i < 50; i++) { message.buf[0] = i; message.id = 0x1; message.len = 1; myCAN.write(message); Serial.print("Message Sent "); // Modified DMK 09-04-2017 Serial.println(message.buf[0]); // Modified DMK 09-04-2017 digitalWrite(ledPin,HIGH); delay(delayTime); digitalWrite(ledPin,LOW); delay(delayTime); } if (myCAN.available()) { Serial.print("Message Received "); // Modified DMK 09-04-2017 myCAN.read(rxmsg); Serial.print(rxmsg.buf[0]); // Modified DMK 09-04-2017 Serial.print(" "); // Modified DMK 09-04-2017 Serial.println(rxmsg.buf[1]); } }
Hello, I would like to know the code and the electric circuit, I am an Engineering student. My project is that, I would appreciate your help. My mail is mohamed.moumni93@gmail.com
Hey, I used an H-Bridge for each phase of the motor. The 3.3V outputs from the FPGA were used as input signals to the H-bridges. Hope this helps. en.wikipedia.org/wiki/H_bridge
Oh, now I see the 8 low power transistors on the bottom right of the breadboard. Thank you. How further should I go to implement microstepping and an UART fifo to receive and process g-code instructions?
In the lower right hand corner of the Altera board, there is a red wire going into that gold connector. That wire is connected to a function generator producing a square wave, at whatever frequency I want. That is used as the clock signal. Kind of a cheap way out, but didn't have time to implement it in verilog :)
sorry for the dumb question , but why dot you need the transceiver? doesn't the Teeny's CAN capabilities have that built in? What the transceiver actually do that the Teensy doesn't ? I
+Sam Pati The teensy has what is called a CAN Controller built in. That deals with all of the logic used in the CAN communication, but because of the way that CAN works, you need a transceiver to actually act on the CAN bus. Might be the best explanation. I learned most everything that I know about CAN from it's Wikipedia page. en.wikipedia.org/wiki/CAN_bus
+Mario Ricardo Mostalac Morales Hey, I am using the FlexCAN library for teensy. You can see at 0:51 that one of my messages has an ID of 0x1 and the other has a message ID of 0x2. I don't know if this helps.
thanks for posting this. love the plane as a micro to glide around. I am sure we all love to try and see how long it floats up there with a cam, and looks great, just not sure if it is worth it all the time. I do not own a radian yet, but more I watch these clips, I want one thanks for a excellent test and clip
haha actually that is something that i was having problems with. my normal was about a foot under back during this season. Now i find that it helps to try and jump up as high as you can at take-off. you can't jump if you are under that much
Hey how do you keep from running under I keep having to move my steps back but every time I still wind up running 6 inches to a foot under on my plant any tips?
