Re: DMD try separate scrolling run

If the total length of what you're trying to display is less than 255 characters, put your words together in a String variable then display that. There's an example of doing so in the DMD guide here: http://www.freetronics.com/pages/using- ... ronics-dmd

Re: Problems with Ethermega and SD Card

Every time it is powered down and then powered up again I have serial port issues - typically the red led stays on and bright and the port is not listed in the list of ports. I disconnect and connect again and the port number (10) becomes available. The red led dims to the faintest glimmer. I'll se...

Re: [Solved] Dodgy soldering on EtherTen?

Just had a board with exactly the same problem, also from JayCar. Unfortunately, I made it worse, attempting to fix it and now the connector has come right off so a photo probably isn't much use at this stage. Pity I didn't look here before mucking with it! Could you please send me a direct message...

Re: Problems with Ethermega and SD Card

Hello Thanks for buying an EtherMega. Yes, the CS line for the microSD card is still 4. The cardinfo.ino sketch that comes with the SD library in the IDE is fine, however you need to change the chipSelect to 4. One more thing, please format the memory card with FAT (not FAT32 or NTFS etc). Finally, ...

Are you saying it's a problem with the sketch? Because It doesn't seem like any other sketch works either :(
Is there anything else I can do without another arduino to get any sketch working?
Can you send me a direct message through the forum? Thanks.

Re: Sketch to get a button to print a letter

Looks like your sketch might be taking over the USB with the keyboard functions.
Do you have an another Arduino or USBASP? If so, reflash the bootloader by following the instructions here:

Re: Adding second ATmega328P??

Actually, is there any info you have regarding projects using two 328p MCU's? Maybe the prototyping area might serve better than another shield. My Eleven is turning into a tower! Afraid nothing springs to mind apart from the I/O controls. If people want faster, they'd usually work on optimising th...
