LCD 1602 and i2c

Google translation French / English
Hello
Who can give a sample program to use a PICAXE M2 and this display: Connection i2c, PCF8574T circuit on the i2c / Parallel Circuit
and the classic HD44780 on the LCD 1602.
For this to be useful to all, the example could
- Display the word "VOLTAGE" on the first line
- A numerical value (using #b1) followed by the word" VOLT "on the second line

Interface + lcd 1602 --ATTENTION -- NOTE : Fixed address is 0x27 , it can't be changed !!!

The person who will give this program Rendra A VERY GREAT SERVICE TO ALL
thank you

The general idea with the forum is that assistance and advice is given to those who are interested in writing their own programs.

You might not get many reponses if you post a requirement for someone to write a specific program for you.

The PCF8574T is a simple I2C controlled I/O expander so a lot will depend on how it is connected to the LCD. More details on using PCF8574 here ...

I'll be glad to do it.
I get $850us a day, say 970 euros. 3 day minimum + expenses, payable in advance of course.
Can't fit you in until July I'm afraid.

There are some past threads on i2c/TWI based communications LCD modules that you may wish to read.

Knowing the interface chip is the first part (hippy has indicated this as the Philips/NXP PCF8574T in above thread), and
verifying the connections between the interface chip and LCD module is also necessary before specific code can be prepared.

Unfortunately I cannot open a .rar archive file (only .zip) on the PC I am current at so unable to see the documentation at the link provided in Post 1.
