Yes, I think it should be possible to change the bus speed when the device takes over the mastership of the bus, I shall look into that. > Next is general, could it be possible to provide user with option to set I2C > speed (clock) rather than prescaler value? I can't see any way to translate the SCL/SDA values that are need to calculate the i2c speed into the MUL + ICR values that need to go into the frequency divider register; the RM just provides a one big LUT for this. -- Configure bugmail: http://bugs.ecos.sourceware.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
