Yes, I am > > being lazy and not digging into the code. I took care of this Now if you enter 0 for delay, the device shall use default value. Example: Following device will look conservatively for 100kHz (10000 [ns]) CYG_I2C_DEVICE(i2c_dev, &cyg_i2c0_bus, 0x4cu, 0, 0 ); Please test this and if you are happy I think I could commit.
