XRPL-monitor-ESP32

XRPL monitor is a micropython script to monitor the XRP Ledger volume and price through a ESP32 board with a 2.4" screen attached.

Hardware

You will need the following hardware or equivalent (15$ approx plus shipping costs if they apply):

• A ESP32 board like the Wemos Lolin D32 PRO (8.8$ - I used the 4MB-flash one)

• A 2.4" TFT display (5.9$)

• A display cable to connect both (0.8$)

Installation instructions

Install Loboris' Micropython firmware

Loboris has a wiki a wiki with complete instructions to build and/or install its firmware. The following is a shortened version for Linux only:

• Download or clone Loboris' MicroPython firmware for the ESP32 , and unzip it.

• Open a terminal and change directory to the firmware's location:

  cd .../MicroPython_ESP32_psRAM_LoBo-master/MicroPython_BUILD/firmware/esp32_psram_all_bt/

• Plug the board to your computer's USB port, and get your device location (usually /dev/ttyUSB0):

  ls /dev/ttyUSB*

• Flash the firmware:

  ../flash.sh -p dev/ttyUSB0

Install XRPL monitor

• Clone or download this repository, unzip it and and change directory to your extracted copy.

• Edit the file boot.py to set your wifi ESSID (the network's name) and its password instead of < WIFI_ESSID > and < WIFI_PASSWORD >.

• Install rshell (you'll need the python3-pip package):

  sudo pip3 install rshell

• Reset your ESP32 device with the reset button, and connect into it with rshell:

  rshell --buffer-size=30 -p /dev/ttyUSB0

• Copy the needed files into the ESP32: boot.py, consola18.fon, RippleDataAPI.py, xrp.jpg, xrp_basic.jpg and XRPLmonitor.py

  cp <file_name> /pyboard/flash
