2,9" EPaper Display not working

[helmar74]

Hi,

I connected a 2.9" EPAper Display to Wemos Mini:
Here's how I connected:

WEMOS <-> DISPLAY
3,3 <-> VCC
GND <-> GND
D7 <-> DIN
D5 <-> CLK
D2 <-> CS

The Disply is set to 3-wire SPI with jumper-

Here's my Setting in Tasmota Webinterface:

My Problem is, that I can't set Displaymodel to 5:
12:37:46 CMD: displaymodel 5 12:37:46 MQT: stat/sonoffStandard/RESULT = {"DisplayModel":0} 12:37:49 CMD: displaymodel 12:37:49 MQT: stat/sonoffStandard/RESULT = {"DisplayModel":0}

When I enter 5 as Displaymodel, always 0 is shown in Webinterface.

What do I make wrong here?
Do I have to enter a Adress?

Here are my Setting in my_user_config.h:
`// -- SPI sensors ---------------------------------
#define USE_SPI // Hardware SPI using GPIO12(MISO), GPIO13(MOSI) and GPIO14(CLK) in addition to two user selectable GPIOs(CS and DC)

#ifdef USE_SPI
#ifndef USE_DISPLAY
#define USE_DISPLAY // Add SPI Display support for 320x240 and 480x320 TFT
#endif
#define USE_DISPLAY_ILI9341 // [DisplayModel 4] Enable ILI9341 Tft 480x320 display (+19k code)
#define USE_DISPLAY_EPAPER_29 // [DisplayModel 5] Enable e-paper 2.9 inch display (+19k code)
#endif // USE_SPI
`

Thanks a lot.

Now I changed settings to:

Now I get:
12:59:00 CMD: displaymodel 5 12:59:00 MQT: stat/sonoffStandard/RESULT = {"DisplayModel":4} 12:59:04 CMD: displaymodel 12:59:04 MQT: stat/sonoffStandard/RESULT = {"DisplayModel":4} 12:59:09 CMD: displayaddress 12:59:09 MQT: stat/sonoffStandard/RESULT = {"DisplayAddress1":113} 12:59:48 CMD: display 12:59:48 MQT: stat/sonoffStandard/RESULT = {"Display":{"Model":4,"Mode":0,"Dimmer":1,"Size":1,"Font":1,"Rotate":0,"Refresh":2,"Cols":[16,8],"Rows":2}}

But still no Text output with "Displaytext BLABLA"

[Jason2866]

DisplayMode 0?
DisplayModel is 4!!
#define USE_DISPLAY_EPAPER_29 // [DisplayModel 5] Enable e-paper 2.9 inch display (+19k code)

[helmar74]

Why can't I set to Model5?
`13:15:43 CMD:*displaymodel 5

13:15:43 MQT: stat/sonoffStandard/RESULT = {"DisplayModel":4}`

[helmar74]

Here's my current setting:

Here's how I connected:

WEMOS <-> DISPLAY
3,3 <-> VCC
GND <-> GND
D7 <-> DIN
D5 <-> CLK
D2 <-> CS

Is it correct connected?

[Jason2866]

For display(s) i still recommend the gemu fork....
Connections seems correct

[helmar74]

MOSI must be connected to DIN Port of EPaper Display?

[helmar74]

But Why can't I set DISPLAYMODEL 5 ?

[Jason2866]

I have this setup

[helmar74]

You have connected a E-Paper Display on GPIO 12-14?

[Jason2866]

yes, i use gemu fork. He has implemented software SPI

[helmar74]

OK, thanks. But Software SPI is also implemented in Tasmota 6.4.1...
Can you pleaes post the result of displaymodel, displayaddress and displaymode
command?

Here are my settings:

connected as you did...
Still not getting text output

[Jason2866]

Displaymodel 5
Displayaddress 113
Displaymode 0

I dont know if the ePaper works with latest orig. Tasmota!

[helmar74]

I tried to compile gemu fork, but i get this error:

Tried again with original tasmota. I can only select Displaymodel 1-4, but not Displaymodel 5.
Here's my_user_config.h:
`
#define USE_DISPLAY // Add I2C Display Support (+2k code)
#define USE_DISPLAY_MODES1TO5 // Enable display mode 1 to 5 in addition to mode 0

... and here my current settings:

[arendst]

Ah, I see I forgot to change the define USE_DISPLAY_EPAPER in file xdsp_05_epaper_29.ino at line 22.

If you compile yourself you might want to try to change it in

#ifdef USE_DISPLAY_EPAPER_29

and try again.

[helmar74]

Hi, thanks. In which line should I enter the code?

[Jason2866]

As Theo wrote line 22

[helmar74]

Hi, I changed it, now I can select displaymodel 5.

... But I still can't display a text.
16:55:49 CMD: displaytext [I] 16:55:52 MQT: stat/sonoffStandard/RESULT = {"DisplayText":"[I]"} 16:55:56 CMD: displaytext [z] 16:55:56 MQT: stat/sonoffStandard/RESULT = {"DisplayText":"[z]"} 16:56:04 CMD: displaytext asfdsfdsf 16:56:04 MQT: stat/sonoffStandard/RESULT = {"DisplayText":"asfdsfdsf"}

Do I make something wrong?

[helmar74]

After a "hard" reboot (power off and on) it works!

These are my current settings:

Thanks a lot for you help ;-)

[arendst]

Congratulations!!

Alas my e-paper seems to be broken. It uses a lot of current while only power is connected so I guess it's dead. Just ordered a new one...

I'll update the driver file with the correct define so it will work from dev 6.4.1.4 and up.

[mraczka]

When I set up WeMos like @helmar74 my device reboots and deletes all pin configuration. Any idea why?

Delete flash with esptool erase flash. After that flash Tasmota again

[mraczka]

Nothing changed. Any other idea?

[arendst]

You loose configs as your device does many reboots in a short period of time. If you try to get an e-paper display functional this is most likely caused by miscommunication between your device and the display.

Depending on the kind of e-paper you have you might need more control over the e-paper interface.

My first e-paper display contained a 5V to 3V3 converter for both power and data lines. It only needed the 3-wire SPI interface (you need to re-solder the jumper on the back of the display) to function.

My seconds e-paper display does not have this voltage converter and to function it needs to control both DC and RST signal line too. I had to connect them also to as relays configured outputs. After a power on of the device you will have to tweak with these relays to get the display going. My current config looks like this:

After power on nothing happens. After a restart the display is updated.

Not nice but this leaves you to document a better way.

[tremichl]

Same problem here as @mraczka commented. When I set up WeMos D1 mini like @helmar74 my device reboots and deletes all pin configuration. As all SSPI ports in this case are outputs only, it should be possible to save SPI setup with no display connected? I have tried that, same problem. Erasing flash doesn't help either. Used pre-compiled version 6.6.0(Display) with Core 2_5_2
Any ideas?

Hi,

I also have the problem that I cannot use the display.
I have a waeshare 2.9 V2.1 and bridge it in 3-wire SPI mode. On the ESP8266 (wemos D1) I have GND, 3.3V, CS on D8 (GPIO15), DIN (MOSI) on D7 (GPIO13) and CLK on D5 (GPIO14) as described above. Precompiled Tasmota-display.bin (9.3.1).
Configured:

Displaymodel 5, Displaymode 0

Nothing comes of "displaytext blahblah".

What am I doing wrong.

Greetings Florian

Hello @hardlog,

did you manage to get the e-paper display working?

You have to use SSPI

I am also having trouble getting a Waveshare 2.9" EPD to operate using just about every combination of ideas suggested here!

This is from the console on boot:
00:00:00.050 CFG: Loaded from flash at F9, Count 187 00:00:00.055 QPC: Count 1 00:00:00.058 SPI: Hardware using GPIO14(CLK), GPIO13(MOSI) and GPIO12(MISO) 00:00:00.019 DSP: E-Paper 2.9 00:00:00.022 Project tasmota Display Wemos D1 Version 9.3.1(display)-2_7_4_9(2021-03-31T00:15:11) 00:00:00.659 WIF: Connecting to AP1 Private Network Channel 7 BSSId 10:7B:EF:F3:D2:78 in mode 11n as display-1505...

to me this is suggesting that all is well for hardware SPI. The connections are correct MOSI to DIN looks good and when I select EPAPER29 CS for the chip select line, the firmware automatically eables [displaymodel: 5] as displayed in the console output?

Any more ideas? FYI: I have also tried various combinations of SSPI also...

Thanks

Garry

lilygo epaper 2.9 T5 V2.2 - nach 2 Jahren noch keine Lösung für einen Betrieb mit Tasmota - oder ?

[Jason2866]

There is an update. Don't know if other 2.9 are working with.
#17627

without parameter column A - no function possible
