The there is more error in the frequency than some end users will want. It seems to run about 10% too slow. In the CDL "SMB register options" is misspelled. register is missing an r. I don't have means at the moment to test SMB options. I suggest this is tested after releasing this code. When the STM32 I2C is in a similar state to this code, I can build hardware that supports built in ALERTB processing for both processors and test the SMB support. The current patches seem adequate for I2C and work fine with my large application. I would like to test default clock speed, meaning the frequency in the CDL. How do I write code that uses the default rather than .i2c_delay. Yes, I am being lazy and not digging into the code. -- You are receiving this mail because: You are on the CC list for the bug.
