@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 Tamper 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 Tamper push-button : LED1 turns ON and all other LEDs are OFF, on the N
eval boards connected to the bus.
- Press on Tamper 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 Tamper 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 STM32F0xx devices.
- This example has been tested with STM32091C-EVAL board and can be
easily tailored to any other supported device and development board.
- STM32091C-EVAL Set-up
- Use LED1, LED2, LED3 and LED4 connected respectively to PE.00, PE.01, PE.07
and PE.08 pins
- Use Tamper push-button connected to PC.13
- Connect a male/male CAN cable between at least 2 EVAL CAN connectors (CN5)
- You have to configure the jumpers as follows:
@verbatim
+-------------------------------+
| Jumper | CAN |
+-------------------------------+
| JP3 | 1-2 |
| JP2 | fitted |
+-------------------------------+
@endverbatim
@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
