I am not a hardware-savvy person. I went with the T-Beam since it was the first choice on the list. I noticed somewhere that it’s not possible to just hold the screen in place, and that some soldering would be required. Are both parts true?
I’m not super stressed about not having a screen since it looks like there’s a way to get the PIN info from the USB readout, but it would be neat to have.
So assuming I can find a tech friend who can solder it, what’s the recommended link to buy a screen? I’m from the US btw.
Also if anyone knows a good place to get the 18650 battery too I’d like to know
Welcome to the forum @leer10! Yes you really need to solder the screen in place or at a pinch, solder header sockets on the TBeam for the screen to connect to. You are right though, you can find the bluetooth pairing code within the debug output but it is easier with a screen.
The most common is a 0.96" OLED using an SSD1306 driver I/C. Ideally you need to find one that the pins are labeled VDD -1, GND - 2, SCK - 3, SDA - 4. This way they line up perfectly with the TBeam pins without further soldering!
I’m unsure on 18650’s in the US (I’m not there) but unprotected cells fit best in the TBeam. Any 18650 that mentions protection is a little bit longer and a bit of a squeeze.
As suggested in the Github readme. That board has no OLED display included. I would like to get
one that would be compatible with the current software. Preferably on the larger size.
ooh! the q&a on their site says this screen uses a sh1106 controller (instead of the ssd1306 controller used on the standard screens). @mrvdbrecently added support for that display, but only for his custom board. In theory it would be possible to dynamically probe for the device and use it, but no one has done that work yet.
I suspect that if you uncomment this line and rebuild using platformio, it will work:
// The SH1106 controller is almost, but not quite, the same as SSD1306
// Define this if you know you have that controller or your "SSD1306" misbehaves.
//#define USE_SH1106
Great you got it working! The ones I linked use the ssd1306 so they worked by default. It was surprisingly hard to find a larger screen with the right pin config and controller.
I am also looking for something bigger then the 0.96" oled
Has anyone tried a compile using either of these display board ?
The 1.5" I2C oled using drivers SSD1309 or SSD1327 in the u8g2 library
I see the gnd and vcc pins are reversed,
links for the 128x64 or 128x128:
Recompiling and reflashing at the moment. Would be happy to test dynamic probing if anyone is looking for a tester. I have a TTGO with the original SD1306 and now this one with a SH1106
i‘was have the same problem, i’was recompile and flash for SH1106, i‘will be nice if the app, check the screen, before start automatic, and the user press a button if he can read a message, and it will save … and dont ask this again …
