Part Number: TMS570LS1227
Thank you for the TI's employee making this un-official /un-released app note & the code. It's a big help on those TMS's without dedicated I2c.
Did a change to one instruction - line 83, changed pin=0 to SDA_PIN, which then makes it easier to remap SCL,SDA by changing them only on the top lines 1, 2.
I've successfully tested it's working upto 200KHz, it starts to fail beyond it. But my bus/VCLK2 speed is lower vs. what the TI"s app note used - 50MHz vs 90MHz.
