Does anybody try to run any example included in STR91x Standard firmware Library? I try to port with keil the Can example, but I need to modify the I/O led function for switch on the led! The other Can function function correctly?

Thanks runblade

I ported the code for str9x dongle, and I redirect the Led output in GPIO6.

see the code below:

void IO_Init(void)

{

/* P9.0, P9.1, P9.2 and P9.3 output*/ /*modify for STR9x dongle Fabio*/

GPIO_StructInit(&GPIO_InitStructure);

GPIO_InitStructure.GPIO_Pin=GPIO_Pin_0|GPIO_Pin_1|GPIO_Pin_2|GPIO_Pin_3;

GPIO_InitStructure.GPIO_Direction=GPIO_PinOutput;

GPIO_InitStructure.GPIO_Type=GPIO_Type_PushPull;

GPIO_InitStructure.GPIO_IPConnected=GPIO_IPConnected_Disable;

GPIO_Init(GPIO6,&GPIO_InitStructure);

/* P5.0 alternate input 1, CAN_RX pin 12*/

GPIO_StructInit(&GPIO_InitStructure);

GPIO_InitStructure.GPIO_Pin=GPIO_Pin_0;

GPIO_InitStructure.GPIO_Direction=GPIO_PinInput;

GPIO_InitStructure.GPIO_Type=GPIO_Type_PushPull;

GPIO_InitStructure.GPIO_IPConnected=GPIO_IPConnected_Enable;

GPIO_InitStructure.GPIO_Alternate=GPIO_InputAlt1;

GPIO_Init(GPIO5,&GPIO_InitStructure);

/* P3.6 alternate output 2, CAN_TX pin 66*/

GPIO_StructInit(&GPIO_InitStructure);

GPIO_InitStructure.GPIO_Pin=GPIO_Pin_6;

GPIO_InitStructure.GPIO_Direction=GPIO_PinOutput;

GPIO_InitStructure.GPIO_Type=GPIO_Type_PushPull;

GPIO_InitStructure.GPIO_IPConnected=GPIO_IPConnected_Enable;

GPIO_InitStructure.GPIO_Alternate=GPIO_OutputAlt3;

GPIO_Init(GPIO3,&GPIO_InitStructure);

// The code below made the led lit!!!!

SCU->GPIOOUT[6] = 0x0055;

SCU->GPIOTYPE[6] = 0x0F;

GPIO6->DDR = 0x0F;

GPIO6->DR[0x0F*4] = 0x0F;

---Using this last 4 lines the led start to lid. But with the previous initialization they don't lid.

Also I put in C:\keil\ARM\INC\St\91x the new .h included in V1.2 lib

Hello Ibtissem!

What port do you use GPIO6 or GPIO9?

GPIO6
