Connect 2.9" eink?

[cloudsun9]

I have connected to
******* E-Ink *********
BUSY 33
RST 4
DC 32
CS 15
CLK 0
DIN 2
Can anyone confirm these connections are still correct?
With 2 boards and 2 screens same result, until I dropped the set pictured, otherwise no response on the screen.
This on 4.4.0 & 4.5.1 & now firmware_v4.6.1_nopsRam.bin.
Is this screen not supported?
Or does it need 5v? I had read that would be a bad idea.
I have seen the photo of an apparently working set.
Any one got a comment?

Did you desolder these ?

[cloudsun9]

Ah! No.
Thank you, tricky job but working now.

I desoldered the two resistors but still not working the display.. I tested the display and it works with arduino nano.

Should I remove or also do the bridge after removing the resitors?

any other idea why it doesn't work? exact same setup except I have also the BMP20 maybe?

Thanks,

Martino

is einc turned on in settings? I had this issue on recent versions.

Don't know actually.. how should I set it to IN settings?

thanks a lot

[Martenz]

Or sorry maybe I misunderstood, if you mean if it turns on in settings, no never. I tried also to flash again firmware and it is not recognised it starts with nodisplay, then from wifi settings I try to set eink but still no power on of the eink.

Should I check something in the serial output when switching on the tbeam?

Thanks

[MaUwJo]

Sorry - I have no I'm only an user - last time when I had issues it wasn't properly soldered. Maybe you can send serial output - there are some debug messages in.

[Martenz]

Some logs from serial:

Sometimes I get this and I can not restart with the button but I have to long press the power or disconnect usb

I tried to check pins solder and also changed Vin 3x3 to 3.3 pin and changed also different GND. nothing maybe it is my moard.. will test it again when I get an other board.. now can I put again the oled or not? I removed the resistors.

If you have some other test I can do let me know.

Thanks Martino.
