We have a code written in Keil for a Tone dialer which is working on our current design. The current design has a LCD, Keypad, EEPROM and tone generator IC. We want to modify the code to perform a specific task.

The current code does the following operation:

- At power-on, it asks to enter a Number ( max. digit is 10) and then you press * followed by #. This will store the number in the EEPROM. Pressing * and # stores the number entered through the keypad

- When you press External Interrupt button, the number stored in EEPROM is dialed.

Now we want to remove Keypad from the design and store a specific number by default which dials the number when external interrupt button is pressed. So no pressing * and # for storing the number in EEPROM.

Next, for testing the code we want to dial 10-digit number and when this code works we want to dial only 2 digit number.

An important part in the code is the delay since we are using the Tone-dialer.

We are sharing the code as the attachment and want freelancer to go through it and let us know their understanding and queries on the code first.

We want a small proposal for the project as well, which should includes the time-frame and approach.

It is not a difficult task for someone who has work earlier on 8051 MCU which is very basic.

Payment will be in milestone and will be release only we test the code on our design. All error will be shared.

We will be providing bonus for work ,if done properly and quickly.

Hello, I designed and patented a POTS emergency autodialer for elevators (you can see in my portfolio). Can you let me know more about the dialer?
