I2C loopback code for TMS320f28377d

Hi Rahul,

For C2000 devices, i2c code for EEPROM interface is only available. I guess you're looking for something similar to that for SPI and SCI, right?

Yes gautam, because right now i dont have EEPROM.
i want to observe the clock and data as we can do in SPI loopback.
Is there any way to achieve this?

Thanks

i am using i2c eeprom example, i set MST and DLB bit of I2CMDR register but still not working
how can i achieve loopback?
Thanks

Rahul check these links:

Let me know if you find them useful enough or if u need more help.

Hi Gautam,
its still not working
I have set up the GPIO pins 91, 92 . I am getting both the lines high iniitially.
when i am writing to I2caRegs.I2CMDR.all = 0x2E60 (i.e master mode loopback enable), SCL and SCL lines are going low and staying low, but i could not observe the clock or data. I am trying to get at least 1st byte.
I am using Example_2837xDI2C_eeprom.c for F2837xd from controlsuite.

is there any other sample code available for i2c loopback?

Thanks,
Rahul
