@par Example Description
|
|
|
|
How to configure the CAN peripheral to send and receive CAN frames in
|
|
normal mode.
|
|
|
|
The sent frames are used to control LEDs by pressing KEY Push Button.
|
|
|
|
The CAN serial communication link is a bus to which a number of units may be
|
|
connected. This number has no theoretical limit. Practically the total number
|
|
of units will be limited by delay times and/or electrical loads on the bus line.
|
|
|
|
This program behaves as follows:
|
|
- After reset, all LEDs are OFF on the N eval boards
|
|
- By Pressing on KEY Push Button : LED1 turns ON and all other LEDs are OFF, on the N
|
|
eval boards connected to the bus.
|
|
- Press on KEY Push Button again to send CAN Frame to command LEDn+1 ON, all other LEDs
|
|
are OFF on the N eval boards.
|
|
|
|
@note This example is tested with a bus of 3 units. The same program example is
|
|
loaded in all units to send and receive frames.
|
|
@note Any unit in the CAN bus may play the role of sender (by pressing KEY Push Button)
|
|
or receiver.
|
|
|
|
The CAN is configured as follows:
|
|
- Bit Rate = 1 Mbit/s
|
|
- CAN Clock = external clock (HSE)
|
|
- ID Filter = All identifiers are allowed
|
|
- RTR = Data
|
|
- DLC = 1 byte
|
|
- Data: Led number that should be turned ON
|

@par Hardware and Software environment
|
|
|
|
- This example runs on STM32F103xG devices.
|
|
- This example has been tested with STM3210E-EVAL RevD board and can be
|
|
easily tailored to any other supported device and development board.
|
|
|
|
- STM3210E-EVAL RevD Set-up
|
|
- Use LED1, LED2, LED3 and LED4 connected respectively to PF.06, PF.07, PF.08
|
|
and PF.09 pins
|
|
- Use KEY Push Button connected to PG.08
|
|
- Connect a male/male CAN cable between at least 2 EVAL CAN connectors (CN4)
|
|
- You have to configure the jumpers as follows:
|

@par How to use it ?
|
|
|
|
In order to make the program work, you must do the following:
|
|
- Open your preferred toolchain
|
|
- Rebuild all files and load your image into target memory
|
|
- Run the example
