# 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.
