I found some solutions talking about 3 wire LCD interfacing,Īll of them use the 4 bit transfer mode & I wondered why ?! especially that the MCU pin count remains the same, so why the rippling overhead ? !!.Īlso they use 74HC164 shift reg.

I/P Arguments: char *,char *,char *->pointers to get the y,m,d.I searched for a way to save more MCU pins while connecting to LCD.

Get Day, Month, Year one after the other.

After selecting DS1307, select the RAM address 0x00 to point to DAY.

Ds1307 ic is enabled by sending the DS1307 id on the I2C bus.

Description :This function is used to get the Date(y,m,d) from Ds1307 RTC.

Cols are connected to higher 4-bits of PORTC.

Rows are connected to lower 4-bits of PORTC.

I/P Arguments: ASCII value of the char to be displayed.ĭatabus = (dat & 0xf0 ) // Send the Higher Nibble of the Data to LCDĬontrol_bus |= 1 <

step9: Send a High-to-Low pulse on Enable PIN with some delay_us.

step8: Select Write operation making RW low.

step7: Select the Data Register by making RS high.

step6: Send the lower nibble of the character to LCD.

step4: Send a High-to-Low pulse on Enable PIN with some delay_us.

step3: Select Write operation making RW low.

step2: Select the Data Register by making RS high.

step1: Send the higher nibble of the character to LCD.
