contained in an “.hex” file. This file must conform to the Intel HEX-32 format. The software does check whether the
program operation has been successful or not.
1 Installation of “Tiny M2Flash”:

1.1 Place the “.obj” file in “C:\”.
1.2 Place the “.exe” file anywhere.

2 “Tiny M2Flash” usage:

2.1 Choose the serial port number that this instance of the program will use to communicate with the digital module.
2.2 Browse the file system and choose the “.hex” file that contains the information to be written into the flash.
2.3 Tie pin 3 of connector YB at the digital module to ground. Turn on the 3.3 V power supply that feeds the digital
      module. This will make it reset.
2.4 Press the “PROGRAM” button once. This will automatically:

2.4.1 Open the serial port.
2.4.2 Send the (machine code) “server” program to the M2 microcontroller. The PC will act as the “client.”
2.4.3 Erase the whole flash chip.
2.4.4 Program the flash with the information contained in the “.hex” file.

2.5 If needed, the button “STOP” can be pressed to stop the execution of that instance of the program in the PC.
      However, this will not necessarily interrupt whatever the M2 was doing. It is recommended that the digital module
     be resetted after “STOP” has been pressed in the program.
2.6 The program will display the message “OK” or “ERROR,” depending on whether the programming operation has
      been successful or not.
2.7 Turn off the power supply.

Note: The progress bar starts growing right after the flash memory has been erased.
