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".
