In this article, let\u2019s implement the MasterSendDataIT API.<\/span><\/p>\n

Assignment:<\/b><\/span><\/p>\n

Implement the MasterSendDataIT API. For that, first, download the file shown in Figure 1, whose link is attached in the resource section, and the file name is I2C_MasterSendDataIT.c. <\/span><\/p>\n

The I2C_MasterSendDataIT.c contains partial code, and the assignment for you is to complete the code.<\/span><\/p>\n

 <\/p>\n

There are a couple of question marks in some places of Figure 1 that you have to remove with the appropriate code. The code should be implemented according to a couple of comments mentioned.<\/span><\/p>\n

For example, look at Figure 2. According to the comments, first, you need to implement the code to generate the start condition, then implement the code to enable the ITBUFFEN control bit, and so on.<\/span><\/p>\n

After completing the I2C_MasterSendDataIT API implementation, copy the entire API, and paste it into the driver source file shown in Figure 3.<\/span><\/p>\n
