DS1307_set_mode(); while(true) { } } From the Datasheet: Depending upon the state of the R/W bit, two types of data transfer are possible: Data transfer from a master transmitter to a slave receiver. The first byte transmitted by the master is the slave address. Next follows a numb...
比如对于 DS1307 芯片:CONFIG_RTC_DRV_DS1307=y. 此外,也可以开启 CONFIG_I2C_DEBUG_* 配置,使内核日志显示更多 I2C 信息,便于后续调试。 第二步:查阅 SoC 的 datasheet,确保 /dev/i2c-* 总线数量不少于 SoC 支持的 I2C(TWI)总线数量,而且存在未被使用的I2C 总线 ...
