Building/Compilating Help

[impeeza]

Hello there, first at all thanks a lot for your great work.

As I mentioned on the #16 (comment) issue and you so kindly answer asking for creating a new issue, here I am.

My «problem» question is:

I only was able to get a Waveshare-S3-Zero, and I am wondering how to build the project for that board. on that board the GPIO pins 34 & 36 are not exposed and the GPIO pins 14, 16, & 38 are small test points on the PCB, the GPIO 44 is marked on the board as RX. so the default buid for S3 will not be usable.

The user @CyberFreek stated on the issue he was able to build a version for the Zero board

The zero board as the S3 lolin have a neopixel embeded and CyberFreek used the next set of pins on the YAML

  led_pin: GPIO1 #blue to logic converter/led
  spi2_type: SPI2 
  spi2_clk_pin: GPIO13 # blue (pn532- sck)
  spi2_miso_pin: GPIO12 # green (pn532- MISO)
  spi2_mosi_pin: GPIO11 # yellow (pn532- MOSI)
  rfid0_spi_interface: SPI2
  rfid0_ss_pin: GPIO10 # orange (pn532- SS)
  neopixel_pin: '21' 

This is the board pinout

He explained what replace some files on the repo and load a docker to build the code, but I really do not know how to load a docker image, I was able to create a ESP-IDF environment on a Ubuntu VM, also I was able to build code using MSYS2 on my Windows Machine

I wonder if there is a way to manually build the code for the Zero board or even if worth to change the code of the project to include that board.

Again, thanks a lot for your time and help.

Glad you are building one.

The esp32-s3-zero is a good board.

I've pushed a branch with the suggested pinout called esp32s3-zero.

git checkout esp32s3-zero
cd firmware
ls /dev/cu*
export USB_ADDRESS=/dev/cu.usbmodemXXXXX    <---------( where xxxx is the id of your esp32)
make esp32-s3-zero

This assumes that you have make and esphome installed on your machine.

Thanks for your response.

I will investigate how to install esphome on my linux virtual machine and let you to know how is going.

Well, Good News:

First My Waveshare-S3-Zero do not shows on my linux machine as /dev/cu.usbmodemXXXXX Only as /dev/ttyACM0 but using that device with the make command the system seems to be installed fine.

Install ESPHome command line on linux is a piece of cake.

I was able to setup my WiFi credentials and the device connected to my network without problem.

Now on the OpenSpool webpage I have control, I have not hooked the PN532 yet, but will be my next task.

An only question: As the Zero board have a WS2812B integrated and managed by the PIN 21, there is need to connect an external LED or can I use the internal one?

Again Thanks a lot for all your help.

Hello there, playing with the files I found on the file esp32-s3-zero.yaml the header says:

  board: lolin_s3_mini
  variant: esp32s3 #TOOD: add support upstream for lolin_s3_mini

I wonder if should be

  board: waveshare_esp32_s3_zero

again thanks.

EDITED: FOUND THE DEFINITION OF THE BOARD ON PlataformIO AND IS «waveshare_esp32_s3_zero»

Yes you'll want to change the board type. This file is just a rough draft, likely additional changes will be required.

Mate, Thanks a lot I just finished the build of the hardware, I did connected the PN532 to the Zero board using welded wires, and connect the board to the USB on my PC, with the serial monitor enabled and everything worked flawless.

I also changed the led_pin: GPIO1 to led_pin: GPI21 on the file firmware/esp32-s3-zero.yaml to use the internal WS2812B led.

So far I didn't connected a external NEOPixel LED and the embedded one on the board seems works "fine" just the red and green colors are interchanged :P

I tested a bunch of blank tags and all where recognized without problem; I have at hand some Ntag213, Ntag215, two unmarked ones which come with the PN532 and some Mifare 1k

My printer is a Creality Hi, so I will be waiting for their support.

I am closing the Issue unless you like to leave open.

This is my current setup

Also seems you can use external NeoPixel LED and do not use a level converter using this trick:

"One trick I've used is to use a WS2812b as level shifter. You add an additional WS2812b as 1st LED, and supply it with a diode from the 5V line. So the 1st WS2812b has its supply lowered to 4.4V, this makes it compatible with 3.3V and subsequent WS2812b's work with 5V." (https://www.reddit.com/r/FastLED/comments/gku4j7/comment/fqtdnxk/)

That Trick, also comes from https://hackaday.com/2017/01/20/cheating-at-5v-ws2812-control-to-use-a-3-3v-data-line/
