#168979 - There is difference for I2C in lpc93x & 66x Responding to: ???'s previous message |
Erik Malund said:
the code generated by the CodeArchitect (free from http://www.esacademy.com) for the lpc935 will work on the 66x. You may want to 'massage' it a bit, but it works 'out of the box' There are basic differences between 2 of them as far as SFR are concern. 1. In case of lpc93x (& 669) there are 2 registors in SFR that decides clock speed. While for 66x (other than 669) only 3 bits decides speed, also these 3 bits are in I2C Control Registor. 2. As speed deciding bits are in control registor; one has to be very carefull while altering contents of registor (I prefer to use setb & clr for bits like STO, STA etc...) in case of 66x (other than 669) Regards, Mahesh |
