1- When I test the program "DataDisplay2" with the code: N2k_SPI_CS_PIN 9 (he says "CAN device failed to open") When I test the program "DataDisplay2" with the code: N2k_SPI_CS_PIN 10 (he says "CAN device ready, Running ...")
So I'm sure CS is on the pin 10.
2- Quartz is a 16Mhz I'm sure.
3- I commented "N2k_CAN_INT_PIN 2" (because on my card it's the 2) because I only have one sensor on my bus (the DST800)
4- CAN_H is the white CAN_L is blue It was good for me.
5- I measured the resistance between the blue and white wires and I got 50k ohms. you can see it on the picture opposite: https://drive.google.com/open?id=1hNGhsF8VQYxYKMLATA7q3OEkh3LL2sGh
I measured the resistance on the arduino card between CAN_L and CAN_H and I get 1k ohm. you can see it on the picture opposite: https://drive.google.com/open?id=1q5l79676sQFGlV3WE8GV92MOC8IlHvIC and https://drive.google.com/open?id=1PJ5BifSC8vgfT_7LKCWT4pXdaw4lD7Gd
Question: 1-The ground of my external power supply have to be connected to the ground of my arduino board?
2- I have to connect the termination resistances. The same like in a picture: https://drive.google.com/open?id=1zlgggP77Eftuzmamiz6bxq9Y5NbVNMf
What are the values of the resistances?
