Not sure why but the blade is choppy looking when scrolling out. I have had this same blade and hilt for about 10 months everything was working fine the only thing different I changed was I got a new 16 GB SD card. Scrolling off seems normal. I checked the battery it’s a full 4.06 volts. The saber operates normal other than that. Any ideas?
Run a speed test on the SD via Serial Monitor. Unless you shorted something out on the board like fried a fet that’s going to be your biggest indicator.
Ok how do I go about the speed test plug it in Arduino?
Do you still have the old previous SD card? Why did you get a different one? I would compare the two with speed test.
- make sure you don’t have DISABLE_DIAGNOSTIC_COMMANDS defined in your config.
- connect USB, open serial monitor in Arduino and send
sdtest
I thought I was getting a better SD card but it might be bad. Patriot from Amazon I don’t recommend it. I had a problem with this brand. I pulled it out and looked at it. Guess should of know it was too cheap. So long story short I may have another bad one.
What is considered bad vs. good. What do you look for?
You want read times over a thousand and like 12 simultaneous streams. It’s been a while since I’ve looked at actual numbers but I think that’s about right.
Follow that link and the steps @Fett263 shared. If you show less than optimal (like below 80% output) it’s not optimal. There’s a link to the recommended cards (I’m mobile so can’t clip and paste it here) that work great. SanDisc being the most popular. That said many of us have had excellent performance from the Kioxia Exceria 32gb.
Side question, before you loaded the fonts onto the new SD did you properly format it to FAT32 format using SD Memory Card Formatter for Windows/Mac | SD Association ?
I ask because I see it far too often users not knowing to do that step and it ends up affecting performance. You can always try wiping and reformatting the card. There’s about a 50% success rate.
*Avoid using proprietary Mac or PC for matters. The SD Card Formatter App does it best.
Yep I formated it on my computer.useing Fat32. On windows. I used the eject too before taking it out.
You should use the tool linked here as suggested, not Windows built-in utility.
Ok ya I’ll get on that. Apriciat that advice 
I have the saber plugged into Arduino on the serial monitor typed sdtest and just says " whut? what am I doing wrong here? I went in the config file and // the Disable Diagnostic _Commands.
Did you upload after commenting out DISABLE_DIAGNOSTIC_COMMANDS ?
I clicked the check program, thought that would do it.
I did down load that SD card formatter. I did the quick format. It must of helped. I used a different card and the problem stopped, scrolling out normal now. I just need to see what the deal is with the other card for now. Thank you.
Just be sure you comment out // DISABLE_DIAGNOSTIC_COMMANDS and then refresh the config. This is the way you then can run SerialMonitor to get the read speed on the SD Card.
Ok thank you, I’ll get that going.
I ran a sdtest to see the numbers on it. I don’t really know if there good numbers. Everything is working fine I just wanted to do it.
Average speed 868.25 kb/s, 9.84 simultaneous audio streams.
Average time to open 6787.21 us
yeah, that’s a bit slow.
This is more than a bit slow.
I’m not sure why, but opening files on this sd card takes 2-3 times longer than normal, which will probably lead to audio glitches.
