Hi! I'm facing the problem of initing the i2c device on my arm board. The device is i2c led dimmer. I did init the i2c bus and did i2c_register_board_info. Should I write the driver for this led dimmer, or I can directly use commands (described in include/i2c/i2c.h) to write the data to the device (i2c_master_send etc...). Thanks in advance! Merry X-Mas and a Happy New Year!
