Posted on May 17, 2011 at 12:31hi all,
I'm trying to test the CAN bus on my hardware.
I use the CAN example program available in the FWLIb.
My hardware is based on the STM32F103VBT6 and the CAN is mapped on PD0 and PD1.
Here is the GPIO initialization
/* Remap the CAN pins on PD0 & PD1 */
GPIO_PinRemapConfig(GPIO_Remap2_CAN,ENABLE);
/* Configure CAN pin: RX */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOD, &GPIO_InitStructure);
/* Configure CAN pin: TX */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOD, &GPIO_InitStructure);
When i put a probe on the CANTX I/O, there's no activity !!!!!
Any idea ?
