Support for Lillygo Ver1 boards

[raytechnical]

I have several LILYGO TTGO Ver1 boards which would could be utilised as I Gates, would it be possible to add support for these please?

[richonguzman]

Are these boards v1.6??

[raytechnical]

The boards are version 1 boards exactly like this https://meshtastic.org/docs/hardware/devices/lora/?t-lora=v1

The OLED pin outs are different from the later versions of this board but the LoRa pin outs appear to be the same?

[richonguzman]

So I will need your help to add this:

Can you provide the pinout list needed for this to work?

Jugué con 2 placas 868 Mhz de este modelo (ahora no los tengo a mano). Los pines OLED se corresponden al modelo de pines del "HELTEC_V2". Faltaría comprobar el pin de Batería para ver donde está.

En su día, lo programé como si fuera un "TGO_T_LORA32_V2_1_915" pero cambié en el código los pines OLED igual que el "HELTEC_V2". Todo funcionó bien, después me di cuenta que las lecturas de voltaje eran incorrectas, pero no le dediqué mas tiempo.

Pero lo demás funciona con heltec v2 ?

Porque no intentas con Lora32_915?

Here is the pin out diagram:-

Buenas tardes,
De este modelo solo tengo uno para hacer pruebas (lo tenia escuchando satélites) y no tengo mas para 868 para poder testear al 100%.

Con "heltec-lora32-v2".

• Inicia bien
• Lectura de voltaje interno incorrecto, marca en el lcd 0.28v
• Al cambiar las frecuencias a 868 se bloquea en la pantalla de inicio.

Con "Lora32_915" y TGO_T_LORA32_V2_1_915

• Hay que cambiar la asignación de pines del LCD a 4, 15 y 16
• La lectura de voltaje sigue dando 0.28v
• No hay bloqueo al cambiar las frecuencias a 868 y puedo escuchar que emite las tramas con un sdr.

Sobre la lectura de la batería no encuentro información clara y he probado con todos los ADC por lo que imagino que esta placa no tiene divisor interno para la lectura.

there is not much info about the pinouts of V1.0

sadly its not recommended to use with battery in meshtastic at all

[raytechnical]

This is the pin configuration from the Meshtatsic Github https://github.com/meshtastic/firmware/blob/master/variants/tlora_v1/variant.h

I have never used a battery on these devices as per recommendations and have only been powered by the USB port.

Hi,
It has been a while since anyone posted, has anyone had any more thoughts on adding support for this board for IGATE only, running off USB power supply?

Many thanks.

could you help me out with all the pinout verification?

I cant find any info about this board to add it

Does this help?

It looks similar to the Heltec board.

It looks similar to the Heltec board.

Thats in respect to the pin outs.

[raytechnical]

I take this issue is still open

Hi All,
I have now managed to get the board working as an Igate, all appears to be working except I am unable to get the OLED display working. Has anyone got any ideas why this does not work with this firmware, I am using ports
OLED_SDA 4
OLED_SCL 15
OLED_RST 16

Many thanks.

[richonguzman]

just as a test, there is in /src/display.cpp , line 24 a :

#if defined(HELTEC_V3) || defined(HELTEC_WS) #define OLED_DISPLAY_HAS_RST_PIN #endif

maybe add to it " || defined(YourBoardsDefinitionName)"

so that it may need the RST pin to be managed

[raytechnical]

I have added that to the display.cpp and re-flashed the board, unfortunately it is still the same, I must be missing something? You are correct in your diagnosis as I have had a look at other coding with this board version and it shows a similar reset sequence for the OLED board.

show please how you added this

Buenas tardes,
Por si sirve de interés, a mi en la versión actual tampoco enciende la pantalla.
Con la build "2024-10-08" que tenía guardada de la última vez que lo probé, enciende bien. Solo cambié los pines.

[raytechnical]

Still no further forward ..... will try again with a new build.
