Raspberry Pi 3B with PiCAN 2 board, Linux raspberrypi 4.4.38-v7
The mentioned device can be setup from the commandline with: sudo /sbin/ip link set can0 up type can bitrate 800000
for instance. Doing so we have a device defined as can0 and bits can be sent and read from the canbus either from the commandline or using python.
The question is how to define this device within javame?
I saw an example w.r.t. SPI where the device was called SPI. With the emulator it works, but on the real HW it doesn't of course! Unknown device!
Some tests to access the gpio in/out works as expected, in the emulated device and on the raspberry HW.
Though I must say not very straight forward. I had to export the code from Eclipse and send it to raspberry using the device explorer, because since I updated to the jdk1.8.0_121 there is noe mean to define the external device within eclipse. Before it worked!
