According to your code, this is not a problem but a normal behaviour, you're calling a startKeyboard before main loop.

When compiling, I get an error.


What do I need to do to get that to work?

arm-none-eabi-strip is required only for CIA/3DS generation. If you only need to compile 3DSX file, just ignore this error.

If you did want the CIA/3DS file, arm-none-eabi-strip is installed as a part of the devkitPro installation on Windows. It should be located in C:\devkitPro\devkitARM\bin. If you add C:\devkitPro\devkitARM\bin to your PATH environment variable then restart the command prompt you're using, it will recognise arm-none-eabi-strip as a command.

@15avaughn @HeyItsJono I'm trying to fix the jap consoles problem. Anyone with jap console if can run this and report me what it prints on the screen, it could be very helpful

Unfortunately I'm on a European console so I don't think I'll be much help. Best of luck though!

Sorry, I can't test it anymore because I downgraded. It seems to be a problem only with the 10.3 payloads on Japanese consoles.

you could try it with the 9.2 payload then...

 

[15avaughn]

I just did, it says:

arg num: 2
arg0:sdmc:/3ds/argtest/argtest.3dsx
arg1:

I don't think it matters for his purposes though because LPP apps work with the 9.1J payload and it probably doesn't show anything out of the ordinary.

Yeah, this is what it should normally returns.
Waiting for someone who wants to try it on a 10.x Jap console.

If you post in /r/3dshacks asking for help I'm sure you'll get some people willing to test it for you.

I did a very simple code to try it out, but the image is showing up in the bottom screen. What am I doing wrong?

bitmap2 = Graphics.loadImage(System.currentDirectory().."/file.bmp")

Graphics.init()

while true do

    Graphics.initBlend(TOP_SCREEN)
    Graphics.drawImage(100,127,bitmap2)
    Graphics.termBlend()

    Screen.waitVblankStart()
    Screen.refresh()

    if Controls.check(Controls.read(), KEY_SELECT) then
        Graphics.term() -- Term GPU before exiting
        System.exit()
    end
end

 

[Rinnegatamante]

Try moving Screen.refresh() before initBlend call and also add a Screen.flip() call before waitVblankStart call.

 

[Substance12]

That fixed it, thank you!

Why does this code cause the text on the bottom screen to rapidly flash?

Screen.waitVblankStart()
Screen.refresh()
Screen.debugPrint(0,0,"words",Color.new(255,255,255),BOTTOM_SCREEN)
Screen.flip()
while true do
Screen.waitVblankStart()
Screen.refresh()
Screen.clear(TOP_SCREEN)
Screen.flip()
end

Cause double buffering, you have to blit twice a text with a function like this: https://github.com/Rinnegatamante/Sunshell/blob/master/LUA/scripts/funcs.lua#L301-L308

On the start of writing an IRC client in this (since MapleIRC is rather dead) and I have an odd issue. Socket.connect() seems to give up too easily, if that makes any sense?

Specifically what I mean is, given code like this:

cns = Console.new(TOP_SCREEN)
Screen.refresh()
Screen.clear(TOP_SCREEN)
Console.append(cns, "Connecting to 192.168.1.201 port 6667...\n")
Console.show(cns)
Screen.flip()
Screen.waitVblankStart()
Socket.init()
client = Socket.connect("192.168.1.201", 6667)

Nine times out of ten it'll instantly pop up with a "Failed to connect to server" error from lpp. But if I keep hammering A to restart the program, that one tenth of the time it'll actually connect and start working.

The server on the other end (I'm using netcat just to test at this point) doesn't even register a connection attempt until the successful attempt.
I haven't checked out what's happening through wireshark yet, but I have a feeling your socket layer is sending a connection attempt and then not waiting enough time (and I mean, this thing hits "Failed to connect to server" within tens of milliseconds) before it waits for the acknowledgement of the connection before giving up.

Tried on r4 and the nightly 3dsx from november from the repo. Don't have devkit set up so I haven't tried compiling my own copy yet.

Sockets in lpp-3ds are in NONBLOCKING state by default. You should do something like this to keep trying connecting:

client = 0
while client == 0 do
 client = Socket.connect("192.168.1.201", 6667)
end

 

[Insidious611]

Good to know and helpful, changes the way I code most of this, but I seem to still have the same problem.

Made some basic test code, ran by itself, to try to isolate the problem.

Socket.init()
client = 0
while client == 0 do
  client = Socket.connect("192.168.1.201", 6667)
end
Socket.send(client, "TEST")
Socket.close(client)
Socket.term()
while true do
  if Controls.check(Controls.read(), KEY_START) then
    System.exit()
  end
end

Behavior seems to depend on lpp-3ds version.

On R4 and the november nightly:

Error: [string "?"]:4: Failed connecting server.

However, on current git:

Error: [string "?"]:6: bad argument #1 to 'send' (number expected, got nil)

This seems to imply that if it can't connect, as of the current git instead of throwing up an error it returns nil. Which is handy, but if I test for that then I just get to debugprint my own way of saying "Connection failed."

On the receiving end, I occasionally get half-open connections which cause netcat to quit as though something connected to it and then left, but mostly seem to get nothing.

Since I did get the net_request_string sample working, I decided to try this just once, seeing as it's contacting the same server:

Socket.init()
client = 0
while client == 0 do
  client = Socket.connect("rinnegatamante.netsons.org", 80)
end
Socket.send(client, "GET /\r\n")
Socket.close(client)
Socket.term()
while true do
  if Controls.check(Controls.read(), KEY_START) then
  System.exit()
  end
end

Exact same result, either "Failed connecting server" or an attempt to send to a nil socket, depending on lpp-3ds version.
