# ----------------------------------------------------------------------------------------
# This file contains information for a specific board - the available pins, and where LEDs,
# Buttons, and other in-built peripherals are. It is used to build documentation as well
# as various source and header files for Espruino.
# ----------------------------------------------------------------------------------------
# ESP32 CYD LCD DISPLAY
# * Graphics initialised as 'g'
# * E.on("touch", e => ...x,y,b ) for tocuh events
# * CN1/P1/P3 for connectors
# * SPK for speaker (analog)
# * FAT Filesystem vioa require("fs")
# A Note about the 'variables' parameter on ESP32 Builds
# ------------------------------------------------------
#
# For the ESP32 build, the number of JsVars is governed by two factors:
# * Available memory
# * Maximum number of JsVars for the used JsVar format
#
# This setting will chose the optimum JsVar format for a given number
# of JsVars.
# If you add PSRAM to your ESP32 or compile with modules removed, you
# may wish to select a value using this table:
#
# Value | Max JsVars | Bytes per JsVar | Maximum References |
# ------+--------------+-----------------+--------------------+
# 4095 | 4095 | 13 | 255 |
# 8191 | 8191 | 13 | 15 |
# 16383 | 16383 | 14 | 255 |
# 65535 | 65535 | 16 | 255 |
# ------+--------------+-----------------+--------------------+
# CAUTION: Chosing 8191 only allows 15 references to a variable. This
# may be too restrictive to run some code.
# Using too large a JsVar format may limit how many JsVars can fit into
# available memory. Using too small a JsVar format will under utilise
# available memory.
