Modifying the config file

The solution to my problem apparently lay in modifying the config file on the SD card supplied with the FUZE. Useful link here.

Changing settings in this file would force the Raspberry Pi to recognise different types of monitor.

Fortunately, my laptop has a SD slot so I can access the files via my laptop.

Day 8:
1. Saving a copy of the config file on my laptop, I opened the original version on the SD card with Notepad ++ (right click on file and select from menu).



2. I first tried the setup for using a VGA monitor with convertor, although I had read of worries about the Pi overheating and components burning out.

3. SUCCESS (of sorts) – over a week after opening the box I finally saw something on the screen when the FUZE powered up. It was a great sense of (small) achievement.

4. But the resolution of the screen was not good. I couldn’t see the whole of the BASIC editor when it opened making it impossible to see the code I was typing.

Day 10:
1. An afternoon spent going through the following process
     a. Load SD card in laptop
     b. Open editor
     c. Make modification to config file
     d. Make a written note of changes
     e. Remove SD card from laptop and insert into FUZE
     f. Power up FUZE
     g. See what, if any, changes have been made to the VGA monitor display
     h. Make a note of remaining issues
     i. Shut down FUZE
     j. Remove SD card from FUZE
     k. Repeat above
2. After numerous attempts I still couldn’t resolve the problem with the VGA monitor

3. Decided to try the same process using the HDMI cable with my TV

4. Managed to get FUZE to work with my TV

5. BASIC editor window is now fully visible but the text in the Python compiler is too small to see clearly.

Interim solution

The current interim set up is as follows:

I am running the FUZE through my TV’s HDMI port. I will focus on BASIC at the moment which displays clearly on the TV.

When I move on to Python I might have to reconfigure the SD card and run the FUZE through my VGA monitor, on which the Python compiler is fully visible.

I actually already have Python installed on my laptop, so can use that as way of learning to code in Python.

Clearly, not ideal but the best I can manage at the moment.

Longer term solution

In the future I might have to purchase a new HDMI-specific monitor but at the moment it will have to be added to a long list of things for which I need to save up. Also I don't have a lot of space on my kitchen table for yet another monitor, especially as there is nothing wrong with my VGA monitor except that it is not HDMI.

There are plans to create a specific HDMI miniature screen for the Raspberry Pi, which might also be good for the FUZE. It is being funded through kickstarter.
