Re: MAX7219 8 Digit Seven Segment Display Module (HCMODU0082)

Hello, I'm using Arduino ver 1.8.5 under Linux 18.04. Version 4 of the 7219 driver would not display all of the cycles in the example files but version 3 did and this is the version I am using at the moment for development. I am attempting to use one of the external interrupts (pins2 or 3) and then ...

Re: Elec Freaks 3.2" Colour TFT touch screen panel (HCARDU00

Andrew, Thanks to your help I have solved the issue. There was a semi orphaned old version installation via Ubuntu Software Installation which did not place the file in the expected place. When I ran the latest version things got tangled. I had to uninstall both then reinstall 1.8.4.

Re: Elec Freaks 3.2" Colour TFT touch screen panel (HCARDU00

Hello, Is there an updated library as this is not allowed under Arduino 1.8.4. It looks like they now prevent the use of "-" and "_". When compiling there is also the error: In file included from sketch_sep11b.ino:4:0: /home/william/sketchbook/libraries/HCTFTmaster/HCTFT.h:40:18: fatal error: SPI.h:...

Re: TFT adapter board / shield for Arduino Mega (HCARDU0098)

Can this adapter also be used with the 2.4" display HCARDU0083 - 01? The info provided on that page points to this adapter for the Mega but the info on the adapter page states that it is for the 3.5" display. Thank you.

Re: Elec Freaks 2.4" Colour TFT touch screen panel (HCARDU00

I have had the HCARDU0083 for some time now as well as the adapter shield and, yes while it's great, i have been struggling to identify any unused pins. For example, although I have not tried, I assume that if I did not want the touch feature I could re-deploy those pins which are explicit. But what...

Re: Data Logger Shield (HCARDU0093)

Hello, The supplied sketch does not compile with Arduino 1.6.9. It seems to dislike "SDFile" so i changed it to "mySDFile". now it compiles but does not save proper data to file, instead it's just a sting of zeros in binary. Please could you have a look? I don't know which version of Arduino compile...

Re: MAX7219 8 Digit Seven Segment Display Module (HCMODU0082

I am attempting to display the time on the 7seg display in the form of 3 pairs of characters (unsigned int) HH, MM, SS. However if any of these have a leading zero then is not displayed and testing using the following: HCMAX7219.print7Seg(1, 8); shows a 1 on the LHS while... HCMAX7219.print7Seg(0, 8...

Re: Data Logger Shield (HCARDU0093)

Thanks. The sketch certainly compiles now. Interestingly, I just downloaded the older Arduino software 1.0.6 and the original sketch compiles.
Regards.
William.
