CAN ISSUE
Posted: Thu May 01, 2014 7:43 pm
I am assembling old quad with DIMU and ESC32. Using QGC1.4 B1 CAN MOT_L is 15 and CAN_MOT_L is 0. ESCS are programmed with r54. Given CAN ID 1,2,3,4 to ESCs.
I had made a CAN cable with 120 resistor at one end. One DIMU I soldered 120 on empty R3 spot.
When I try to arm the ESCs they are not arming. I have not connected power to the ESCs motor side. Each ESCs microcontroller is being powered by 5V from the autoquad's 5V and Ground.
When I try to get resistance from two can terminals (ESCs or DIMU). I am getting very low value of resistance around 1 ohm. I had checked that escs were arming when I use them in PWM mode.
if i disconnect dimu and measure the resistance when all esc are connected to can wire with one end of the wire terminated with 120ohm resistor the resistance is 0.9 ohm.
With dimu not connected the resistance is on R3 on dimu is 120 Ohm???
