@DaDev you around?

Hello, I need your help figuring out how to properly configure the PINs of my board in User_Setup.h for the TFT_eSPI:

// ###### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP8266 SETUP ######

// For NodeMCU - use pin numbers in the form PIN_Dx where Dx is the NodeMCU pin designation
#define TFT_MISO PIN_D6 // Automatically assigned with ESP8266 if not defined
#define TFT_MOSI PIN_D7 // Automatically assigned with ESP8266 if not defined
#define TFT_SCLK PIN_D5 // Automatically assigned with ESP8266 if not defined

#define TFT_CS PIN_D8 // Chip select control pin D8
#define TFT_DC PIN_D3 // Data Command control pin
#define TFT_RST PIN_D4 // Reset pin (could connect to NodeMCU RST, see next line)

here is the schematic :

For example how do you enter an "Extend" pin 1 vs just 1

any hardware recommendation that is the best for counting and for classifier objects. this object is grains

Hey guys, how are you? I'm having a problem with my infrared remote control receiver for my arduino ELEGO. It's properly connected, but the power led (the red one) isn't lighting up. How can i fix this?
G - GND
R - 5.0V
Y - 11 pin

TrueNorthOP•11/22/25, 3:01 AM

can you get a better pic of the sensor please close and clear

Sadzarex•11/22/25, 3:03 AM

ofc

Sadzarex•11/22/25, 3:04 AM

TrueNorthOP•11/22/25, 3:08 AM

everything looks wired ok, If you have a multi meter test to see if your getting voltage ont he gr pins.

Sadzarex•11/22/25, 3:14 AM

nah, i don't have

TrueNorthOP•11/22/25, 3:14 AM

what about a led and resistor?

Sadzarex•11/22/25, 3:16 AM

I thought the problem was the receiver, but what I really want to do is get the hexadecimal code from the remote control, but it's not giving me the code, and I thought it was the hardware.

TrueNorthOP•11/22/25, 3:17 AM

well it has a LED on the board, so Im thinking that it should be lit, maybe it only lights if it recives a signal?

Sadzarex•11/22/25, 3:17 AM

Nah, it won't turn on at all.

Sadzarex•11/22/25, 3:19 AM

@DaDev
Can I send you a video of the serial monitor to show you what I want?

TrueNorthOP•11/22/25, 3:47 AM

Well it dont matter realy

Jolly Lord of the Round Table•11/22/25, 5:48 AM

not related to the arduino,but i want an sbc with no gpio since ill be using it for a home server
any recommendations?

TrueNorthOP•11/22/25, 6:19 AM

I mean I use a libra pi, they are great, they do have gpio but nothing says you need to use it.I also love orange pi, and rock pi's. @Demon Lord of the Round Table

raptor•11/22/25, 7:23 AM

you can use the raspberry pi compute module

TTrueNorth I mean I use a libra pi, they are great, they do have gpio but nothing says you ...

Jolly Lord of the Round Table•11/22/25, 7:24 AM

i was going to get the rock pi s0 but it has wierd proprietary cables?

Jolly Lord of the Round Table•11/22/25, 7:24 AM

im gonna need to solder these since i cant buy them where i am

TrueNorthOP•11/22/25, 7:24 AM

If your running a light server, I would just go with one of the sugestions I mentiond, far far better and lower powered.

raptor•11/22/25, 7:27 AM

i searched libra pi on google and went to shopping tab and it only showed bras and raspberry pis

TrueNorthOP•11/22/25, 7:27 AM

sry

TTrueNorth sry

raptor•11/22/25, 7:28 AM

is it not a very common board?

Jolly Lord of the Round Table•11/22/25, 7:28 AM

ye the libra pi gets me too the libra sweet potato sbc

raptor•11/22/25, 7:28 AM

i have heard of orange pi but haven't heard of libra pi before

TrueNorthOP•11/22/25, 7:29 AM

this is the brand. https://www.amazon.com/Libre-Computer-Potato-AML-S905X-CC-V2-Alternative/dp/B0CHHJX44N?

JJolly Lord of the Round Table ye the libra pi gets me too the libra sweet potato sbc

raptor•11/22/25, 7:29 AM

ah i found it after adding sbc to the search query

Jolly Lord of the Round Table•11/22/25, 7:29 AM

ye those are way too costly lmao

raptor•11/22/25, 7:30 AM

also you can use an old phone as your server if you dont wanna buy an sbc

raptor•11/22/25, 7:30 AM

i am sure there are software that make it super easy

raptor•11/22/25, 7:31 AM

why does almost every sbc have "pi" as suffix

raptor•11/22/25, 7:31 AM

are they all trying to copy rpi?

TrueNorthOP•11/22/25, 7:33 AM

Well fyi one reason why some of the ones i sugest, is. 1 no sd card needed after first boot.
2, auto power on in power outtage.
3 chips shut down perferals for things not activly being use.

Jolly Lord of the Round Table•11/22/25, 7:34 AM

I think ill just get a pi3

TrueNorthOP•11/22/25, 7:38 AM

ok, get 10 or so cards.

TTrueNorth ok, get 10 or so cards. 😄

Jolly Lord of the Round Table•11/22/25, 7:42 AM

cards?

in parall it would
