I have downloaded that and it does work.
But, your documentation leaves so much to be desired / it would be great if this could be documented somewhere rather than in a git repo.
Some of us do read documentation / and don't necessarily consider git to be documentation.
There are steps that must be performed that are not documented anywhere on m5stack's website to get the display to work properly in 540x960 mode.
I have taken running code from an Arduino IDE that allow me to access the SD card but this same source does not work when copied to PlatformIO.
Can you please document all of the things that I have to do to get this forgotten product to work?
Honestly, the worst $70 I ever spent / by FAR!
@zigedzaged123 I have an M5paper, I had to download drivers for win10.
@yellowelise Please follow my instructions about what you need to post to get help.
Also, see what statements are and are not necessary.
@kevindtimm There is such a thing, all of the sketches appear to be on the M5Paper github pages
@yellowelise you can skip the SPI.begin(), it's not necessary.
SD.begin(4); is all that's necessary for that call.
There are issues with SD cards bigger than 16GB in some cases.
BTW, when you report these issues it would be much better if you would report what errors you get as well as how far the program got (show the output)
@veryalien I saw all that information on the back but, when I couldn't get the card to read, I wasn't sure how much of it I could believe. Now that the card works I see how to use that info.
In the test application there is a 'Home Automation' section, it just has some pretty buttons. Is there an arduino sketch somewhere that shows how the m5paper could interface to alexa? Or some of my other smart devices?
@mati I bought 5 16gb cards, tested them yesterday, they work fine. But, I have 32gb that work in all my pc's and my phone but don't work in my m5paper. I did have to use as CS of 4 in the SD.begin() call, this is not documented in the SD_Test example.
@veryalien I received my 16gb cards yesterday and they worked :)
It's rather odd that I have to restart the test app after each insertion/removal to get it to work but they do work.
Note too that you have to use the CS value (of 4) for SD.begin() to work, too bad this isn't documented in the examples (see SD_Test.ino in arduino IDE)
Things are better now, but I can say that 16gb is a ridiculously low value for storage on a 2020 device :(
Now I have to figure out how to implement the home automation bit -> it sure would be nice to connect to my alexa skills and go from there.
@lukasmaximus I'm using the SD_test example, just trying 'SD.begin()' fails. It seems I might have to give it the CS values, but that value doesn't seem to make any difference either (I'm using 4, as that is the value on the back of the M5Paper)
@lukasmaximus Patriot Brand micro SD card. I didn't know there were 'necessary' files, I just moved some generic files into the root directory.
@veryalien I have an amazon order of 5 new 16gb cards coming tomorrow. Crossing my fingers.
@veryalien what size SD card did you use? I have a 32gb that failed and the 16gb that I have floating around seems to be toast.
working hardware (can't make SD card work)
good documentation
working Arduino examples
@powersoft I don't think the M5Paper was anywhere near ready for release. The hardware doesn't work and the documentation is truly awful. I really wish I could get my $70 back.
@m5user My M5Paper won't even read the SD card, I have been trying every example I can find but there doesn't seem to be any actual demo of how this works with this device.
I'm so frustrated with this device already, I just don't think it's worth the $70 I paid, considering it really doesn't have any documentation at all.
I'm running M5Burner on a brand new M5Paper and when I try to Burn the FactoryTest I get the following screen
I just received a brand new M5Paper and configured the WLAN. When I cycle the power or restart the WLAN configuration is lost. Is that correct?
