hai  Saurabh_B,
thanks for the reply. i will give my point of observation, please help.
1) as per the data sheet in NHD-C160100 Diz-FSW-FBW, i have connected  two 10k pullup at (SCL, SDA both) and  five 1uF at Vout,V4,V3,V2,V1. I have made CSB low and RST high. the supply voltage is 3.3 V and measured  supply current is 200uA . so, my question is the supply current is enough to drive the lcd?
2) after running the code based on the previous post(http://www.newhavendisplay.com/app_notes/NHD-C160100DiZ.txt) given by you, i am getting the ACK from lcd after sending each byte,but it is not displaying any data to lcd. (i have checked all the bytes in logic analyser).

3) the NHD-C160100Diz-FSW-FBW used ST7528 controller , if you look at the page no 26 of the ST7528 datasheet(http://www.newhavendisplay.com/app_notes/ST7528.pdf). it mentioned on the NOTE that :"ST7528 IIC interface can not use with other slaver IIC device". The quotes i understand from it is that other slave device cant be used when using lcd display at I2C interface. Please give clarity on the statements or quotes ? and Can i use other slave devices at the same I2C interface when lcd is attached to it?

hello guys,
i need to know whether
1)Can lcd  be implemented with 100 kHtz?
2)Do supply current (Idd) need between 500 microA to 750microA to drive the lcd? since my supply voltage is 3.3 v but the current is less than 500microA?
3) As per the instructions i have connected the lcd  but i am not getting any display in lcd?in the setup i have used pull-up resistor as 10kohms and the capacitor is 1uF.
4) if you have any sample code which is implemented with i2c-dev than please share it.
4) if there any other suggestions,please provide for NHD-C160100Diz.
