After several hours searching for a solution, to convert a html web server file into an ARDUINO PROGMEM readable format, I decided not to waist more time in the internet and wrote a VB6 script, compiled it and the *exe file works perfectly on my system. (on Windows 7 SP1 as well on my Surface with windows 10) How to use: Run html2progmem.exe At the start up screen, drag and drop the *.html file onto the Text Box. After approx. 2 seconds, you’ll find the output file near by your *.html file. Same name as the *.html file but with a *.txt extension. Next step as usual: Open the *.txt file, and copy / paste it into your IDE. That’s it.
