In the program text before the include statement, some compile-time parameters have to be specified, such as which pins are used for the data (SDA) and clock (SCL) lines. For debugging purposes, USART is used, which was discussed in earlier tutorials. You can think of i2c-dev as a generic I2C chip driver that can be programmed from user-space. Altered source versions must be plainly marked as such, and must not be. I am bit confused about the ACK and NACK signals after intializing the ports and configuring the registers. {"payload":{"allShortcutsEnabled":false,"fileTree":{"ebus":{"items":[{"name":".الندم على الذنب والنفس اللوامة ماسك القدم
