TMS320F280025C: Application issues of chips

Part Number: TMS320F280025C

1.I have been encountering a problem while using the I2C reading E2prom routine on the 280025 chip: if I follow the routine to read data, for example, I expect to read two bytes, but the oscilloscope waveform does display three bytes. Do you have any other information besides the 280025 chip technical manual?

About I2C Reading E2PROM

The polling FIFO mode I am using,Specific routines such as compressed packets：

8407.i2c.zip

2.May I ask if you have any information related to F280025I2C FIFO on your end? There are too few descriptions in the specification book.

    The reference manual contains all the information needed to configure the I2C. The attached zip file you made is just a folder of the I2C examples for the F28002x device, this does not help me understand your I2C configurations. Please provide the code you are using to configure the I2C, or which file in the ones you sent me I should be looking at. To clarify:

    1. What addressing mode are you using for the I2C?
    2. Is the F28002x I2C the controller or target device?
    3. It looks like you based your configuration off the example, which example were you using?

    The info we provide in the manual is the most extensive resource we have, can you please elaborate on your questions? The info may be there, but within the registers or another section.
