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! runblade

What port do you use GPIO6 or GPIO9? Best regards

GPIO6
