problem with I2Cm
I am trying to interface i2c EEPROM and RTC (24LC512 from Microchip and DS1307) CY8C28452,
i am using I2Cm module and configure P2_7 as SDA and P2_6 as SCL. also configure pin as OPEN DRAIN LOW and pull up the pins with 4K7 E resistor.
i use the source code provided in data sheet. but it not works. i check with CRO their is no pulsing on P2_7 as SDA and P2_6 as SCL. then i change pull up to 2k2 but still same thing.also i try with only RTC on board but no op my disply show me error.
i used system clk 24Mhz and CPU clk system clk / 2.
please help me
