Dive into the second class of the Embedded Serial Buses series, focusing on I2C communication with the MSP430F5529 microcontroller. Begin with a recap of previous concepts before exploring the general setup process and specific information for the MSP430F5529. Examine control registers, consult the Family User Guide, and learn to configure I/O pins. Practice sending and reading data, then study an I2C library implementation. Analyze the SHT21 temperature and humidity sensor datasheet, implement its functions, and review the main() function structure. Observe terminal output, summarize key points, and discover resources for further learning in embedded systems and serial communication protocols.
