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 LED1 is ON + - By Pressing on KEY Button : LED2 turns ON and all other Leds are OFF, on the N + eval boards connected to the bus. + - Press on KEY 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 button) + or receiver. + + The CAN is configured as follow: + - 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 + + +User can select CAN1 or CAN2 cell using the private defines in main.c : + +@code +#define __CAN1_USED__ +/* #define __CAN2_USED__*/ +@endcode + +@note When using CAN2, please check that you device is Connectivity line. + + +@par Directory contents + + - CAN/Networking/platform_config.h Hardware configuration header file + - CAN/Networking/stm32f10x_conf.h Library Configuration file + - CAN/Networking/stm32f10x_it.c Interrupt handlers + - CAN/Networking/stm32f10x_it.h Interrupt handlers header file + - CAN/Networking/main.c Main program + - CAN/Networking/system_stm32f10x.c STM32F10x system source file + + +@par Hardware and Software environment + + - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density, + XL-Density and Low-Density Devices. + + - This example has been tested with STMicroelectronics STM3210C-EVAL (Connectivity line), + STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL (Medium-Density) + evaluation boards and can be easily tailored to any other supported device and + development board. + To select the STMicroelectronics evaluation board used to run the example, + uncomment the corresponding line in CAN/Networking/platform_config.h or stm32_eval.h file + + - STM3210C-EVAL Set-up + - Use LED1, LED2, LED3 and LED4 connected respectively to PD.07, PD.13, PF.03 + and PD.04 pins + - Use Key Push Button connected to PB9 + - Connect a female/female CAN cable between at least 2 EVAL CAN connectors + (on STM3210E-EVAL (CN2)/ STM3210C-EVAL (CN3 or CN4) boards) + - Connector 1 DB9_PIN2 to Connector 2 DB9_PIN2 (CAN_L) + - Connector 1 DB9_PIN5 to Connector 2 DB9_PIN5 ( GND ) + - Connector 1 DB9_PIN7 to Connector 2 DB9_PIN7 (CAN_H) + @note JP6 or JP5 must be fitted. + + - STM3210E-EVAL Set-up + - Use LED1, LD2, LED3 and LED4 leds connected respectively to PF.06, PF0.7, PF.08 + and PF.09 pins + - Use Key Push Button connected to PG8 + - Connect a female/female CAN cable between at least 2 EVAL CAN connectors + (on STM3210B-EVAL (CN2)/ STM3210E-EVAL (CN4) boards) + - Connector 1 DB9_PIN2 to Connector 2 DB9_PIN2 (CAN_L) + - Connector 1 DB9_PIN5 to Connector 2 DB9_PIN5 ( GND ) + - Connector 1 DB9_PIN7 to Connector 2 DB9_PIN7 (CAN_H) + @note JP6 must be fitted. + + - STM3210B-EVAL Set-up + - Use LED1, LED2, LED3 and LED4 leds connected respectively to PC.06, PC.07, PC.08 + and PC.09 pins + - Use Key Push Button connected to PB9 + - Connect a female/female CAN cable between at least 2 EVAL CAN connectors + (on STM3210B-EVAL (CN2)/ STM3210E-EVAL (CN4) boards) + - Connector 1 DB9_PIN2 to Connector 2 DB9_PIN2 (CAN_L) + - Connector 1 DB9_PIN5 to Connector 2 DB9_PIN5 ( GND ) + - Connector 1 DB9_PIN7 to Connector 2 DB9_PIN7 (CAN_H) + @note JP3 must be fitted. + +@note Any unit in the CAN bus may play the role of sender (by pressing on the + key) or receiver. + +@par How to use it ?
