#158961 - How to write ?
Responding to: ???'s previous message
Hi Andrew,

Can I write something in e2prom using i2c_transmit() function from CA ?

I have a Global variable called i2cVector[30]. It's a static unsigned char.
I wrote 0x00 to indicate the first address, and 0xA5 is the data that I want to write.
After I call i2c_transmit function to perform the transmission.

Can I do it ?
  i2cVector[0]=0x00;   // MSB
  i2cVector[1]=0x00;   // LSB
  i2cVector[2]=0xA5;   // data to write
  i2c_transmit(AT24C256);

PS. I define AT24C256 as 0x50 (0xA0 >> 1)

I put two resistors 3k9 as pull-up.

Tks
