Nextion displays have an SD card reader.
[b:c74f2f606e]This program works only withe the "intelligent" nextion Series.[/b:c74f2f606e]
It's used to load HMI programs, but it can also be used for video files, sound files, and as a data storage medium. It's this last use that I've been trying to understand.
I use AVR-DOS too but for small list the Datacontrol tool is enough.

I add a powerpoint to explain my works
and all files to use it.

JP :wink:

you should post a sample that will demo this.
serial buffered input is used a lot and the only difference between xtiny/normal AVR is that other registers need to be accessed.
i also do not recall that 3217 has some specific difference.
for your info : when the buffer is full it will not store more data.
so make a small as possible example and test it. when it demos this bug post it. you should also give info about the data you send.
that said : when you read data and add it to a string and do not check the string length it can overwrite the string. bur that is USER code not a built in function/code.

and finally when you made your own hardware post the schematic too.

Hello guys. I have encoutered another buffer bug seems to me at Atxtiny3217. From some reason exceeding buffer size start causing random executing errors those errors are perfectly repeatable. The thing is: Let say we have Config serialin = 50. If come more bytes than this, let say 80+ bytes, some variables gets corrupted, mainly dimensed with WORD length. It look like buffer continues to write in SRAM where other variables are already stored and thus overwriting them. Code then starts act like crazy. Somethin starts executing when it shouldn't, primarily I would say thanks to corrupted variables. Where should be zero is one and magic starts to happening then.

It is not presented in my DAT folder,too.

it keeps to be a problem. some bots (various sources) open a lot of connections.
while i now blocked IP ranges i will look into a better solution : only allowing IP from Germany/Austria/Swiss
After all it is the German BasCom Forum.

It seems, that specifically this one is not presented. At least in my DAT folder.

do you have the xtiny add on?
it is an xtiny specific DAT file.

Please tell me where can I find "AVRX64DA32.dat"?

Thank you ~

thanks, it is up again. yesterday i also had to restart because it was down.
some bots from Brasil stress out the server. i probably end up in banning whole of Brasil.

Currently down again (probably since at least yesterday, 18.03.2025) :wink:
