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 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 Directory contents - CAN/CAN_Networking/system_stm32f4xx.c STM32F4xx system clock configuration file - CAN/CAN_Networking/stm32f4xx_conf.h Library Configuration file - CAN/CAN_Networking/stm32f4xx_it.c Interrupt handlers - CAN/CAN_Networking/stm32f4xx_it.h Interrupt handlers header file - CAN/CAN_Networking/main.c Main program - CAN/CAN_Networking/main.h Main program header file @par Hardware and Software environment - This example runs on STM32F405xx/407xx, STM32F415xx/417xx, STM32F427xx/437xx and STM32F429xx/439xx devices. - This example has been tested with STMicroelectronics STM324xG-EVAL (STM32F40xx/ STM32F41xx Devices), STM32437I-EVAL (STM32F427xx/STM32F437xx Devices) and STM324x9I-EVAL RevB (STM32F429xx/STM32F439xx Devices) evaluation boards and can be easily tailored to any other supported device and development board. - STM324xG-EVAL and STM32437I-EVAL Set-up - Use LED1, LED2, LED3 and LED4 connected respectively to PG.06, PG.08, PI.09 and PC.07 pins - Use KEY Push Button connected to PG15 - Connect a female/female CAN cable between at least 2 EVAL CAN connectors (CN10) - You have to configure the jumpers as follows: @verbatim +-------------------------------+ | Jumper | CAN1 | +-------------------------------+ | JP3 | 2-3 | | JP10 | 2-3 | | JP7 | 1-2 | | JP9 | fitted | +-------------------------------+ @endverbatim - STM324x9I-EVAL RevB Set-up - Use LED1, LED2, LED3 and LED4 connected respectively to PG.06, PG.07, PG.10 and PG.12 pins - Use KEY Push Button connected to PC13 - Connect a female/female CAN cable between at least 2 EVAL CAN connectors (CN22) - You have to configure the jumpers as follows: @verbatim +-------------------------------+ | Jumper | CAN1 | +-------------------------------+ | JP10 | 1-2 | | JP11 | fitted | | JP16 | fitted | +-------------------------------+ @endverbatim @par How to use it ? In order to make the program work, you must do the following: - Copy all source files from this example folder to the template folder under Project\STM32F4xx_StdPeriph_Templates - Open your preferred toolchain - Select the project workspace related to the used device - If "STM32F40_41xxx" is selected as default project Add the following files in the project source list: - Utilities\STM32_EVAL\STM3240_41_G_EVAL\stm324xg_eval.c - If "STM32F427_437xx" is selected as default project Add the following files in the project source list: - Utilities\STM32_EVAL\STM324x7I_EVAL\stm324x7i_eval.c - If "STM32F429_439xx" is selected as default project Add the following files in the project source list: - Utilities\STM32_EVAL\STM324x9I_EVAL\stm324x9i_eval.c - Rebuild all files and load your image into target memory - Run the example *
