I need to make Software / HEX for Programming MCU / and Firmware for PCB Board, which I will present the circuit diagram. The board consists of 2 decoders, MCU G2553 module RV-8803-C7 and EEPROM 24AA512.

1 / When a PCB receives a power supply it should start time as a stopwatch in the module.

2 / G 2553 should sleep all the time and wake up only by receiving a signal from the decoder when has data.

3 / When the G2553 received the data to put real time from the stopwatch and save it in the EEPROM.

4 / If the power to the PCB is terminated, all information remains in the EEPROM-a.

5 / Make the software to save MAXIMUM current power because the PCB works with a battery.

6 / The program for downloading should be very easy ,to be password protected as the default 123456.

7 / When downloaded, the information itself is has to be encrypted and then can be decoded by the program, with a password of at least 8 characters (12345678 by default), digits, upper and lower case letters and simbols.

8 / Have 3 buttons

8.1 / Download

8.2 / Save

8.3 / Delete.

9 / There should be a window in the program from which you can choose which COM port will be used to connect the PC program to the PCB.

10 / USB to download the information is: Cable USB-serial port converter, PL2303

11 / When the C2553 is awakened to receive the data after receiving the last data packet, wait for 2 seconds and if it does not get another packet to record what it received with Timestamp and after go sleep.
