I am interfacing 24AA64F with Atmel SAM4E, the eeprom speed is upto 400KHz and the processor speed is 120MHz. I wanted to downconvert it. Its my first time working with I2C so having a lot of confusions. there is a register TWI_CWGR and I need a value to be loaded in it. First option may be I...
Hello. I am confused in c programming when a function is called by (pointer to an instance). For example in the code below:
/**
* Set the I2C bus speed in conjunction with the clock frequency.
* param p_twi Pointer to a TWI instance.
* ul_speed: The desired I2C bus speed (in Hz) (ul_speed to...
Its an external eeprom 24AA64F. I have to configure TWI_MMR register (microcontroller: AT SAM4E). Is there any clock generator required? As the maximum speed for eeprom is 400KHz and for microcontroller is 120MHz, For down conversion if I load 0C hex, in which register I should place the value?
Hello
I have to program cortex M4 microcontroller with eeprom to receive and send some bytes. I should use bit fields to program it or complete byte registers such as TW_CR?
