1.1.7. December 12, 2016

Demo Program Changes:

Fixed bugs on LTC4282, LTC4215, LTC4260, LTC4280 due to mismatch in function definition and declaration for various functions w.r.t. argument types and return variables.

Library Changes:

LT_I2C

Bug fixed in i2c_read_byte_data() and i2c_read_word_data(). The I²C bus was getting stuck in a constant loop with either master or slave holding the data line low after continuous reading for long hours. To explain the reason for this, consider the following scenario:

Suppose the slave ACKs on Address byte (write bit) and NACKs on Command byte. The ret variable in the code is set to 1. Since there is no checking for the ret value at this point, the function does not return and goes forward. When the master sends the Repeated Start, the slave sees it as a usual Start.

When the Address byte is sent again (read bit), the slave ACKs. But, since the ret variable is 1, the master tries to send a stop, while the slave tries to send over data. This causes the data line to be confused and the program to be stuck in a loop inside i2c_stop().
