C++ (Cpp) spi__init Examples

Example #1

File: dev.c Project: SEL4PROJ/camkes-arm-vm

int can_setup(int baudrate)
{
	spi__init();
	mcp2515_reset();

	/* Wait until reset finishes. */

			break;
		}
		else {
			udelay(1);
			count--;
		}
		if (count <= 0) {
			printf("CAN controller not responding. Check daughter board connection!\n");
			return -1;
		}
	}

	set_baudrate(baudrate);
	enable_intrrupt();

	set_mode(REQOP_NORMAL);

	return 0;
}
