Functionality of CAN driver can be tested by calling application
"can" in NuttShell. This application sends 100 messages over CAN 1.
lcd:
----
This is basically an nsh configuration (see above) with added support
of ILI9225 176x220 TFT display and test framebuffer application.
Display connection is set to SPI 3 and pinout is following:
CS D8
RST D6
RS D7
SDA D4
CLK D3
Framebuffer application can be started from terminal by typing "fb".
