Hi all!! I was wondering if anyone succeed on using this compass/tilt sensor (http://article.gmane.org/gmane.linux.drivers.i2c/3933/match=hmc6343), without the I2C kernel module? To summarize the challenge here, this device reply to a byte command with 6 bytes before its stop, and it also need a custom delay (1ms) between the read and write commands. Using: adresse=0x32; command1=0x50; //0x50:Headings, 0x55:Tilt, 0x45:Magneto union i2c_smbus_data sixbuff; if (ioctl(file, I2C_SLAVE, adresse >> 1) >= 0) { i2c_smbus_access(file, I2C_SMBUS_WRITE, command1, I2C_SMBUS_BYTE, NULL); usleep(1000); i2c_smbus_access(file, I2C_SMBUS_READ, 0, I2C_SMBUS_BYTE, &sixbuff); } My first 2 values are corrects (Heading) but the 2 others don't vary.... never (for 0x45 and 0x55 commands also). Anyone used the i2c-dev.h userspace functions with this device? Thanks!
