"
The S3, C3, C6 and H2 that have HW CDC JTAG USB port may cause a delay when using HWCDC in Serial by activating CDC on Boot and selecting the USB Mode for Hardware CDC and JTAG. This happens when no USB application in USB Host side is started to receive the data sent by the ESP32xx.
The USB CDC buffer gets full and the Arduino HW CDC layer will timeout, by default 100ms, until give up trying to send the CDC data.
As a workaround, it is necessary to use HWCDC::setTxTimeoutMs(timeout_ms) and set it to zero.

-DALL_JSON_TO_PSRAM -DBOARD_HAS_PSRAM -D WLED_USE_PSRAM_JSON
on -S2, this *doubles* the PSRAM utilization!
before: heap used 85%, PSRAM used 13kb / 21kb
after: heap used 60%, PSRAM used 41kb / 65kb !!
Its not enough to declare "doc" as DynamicJsonPSRAMDocument - PSRAM is not yet initialized when "doc" is created. So we need a trick to get the main doc into PSRAM later, during WLED::setup().
Code is very experimental, may or may not work, and need more testing
-> disabled with "#if 0"
According to the technical manual, GPIO 16 + 17 are used for onboard flash, so cannot be used by WLED.
example buildenv:
[env:esp32_pico]
extends = env:esp32dev_qio80
board = pico32
we can use `-D CONFIG_ASYNC_TCP_TASK_STACK_SIZE=xxxx` to increase the stack size of AsyncWebserver - default is 8196.
This should give us a bit of headroom for new UI items.
We still need PR #94 for more savings.
* Initial checkin for ESP-NOW remote feature
* cleanup irrelevant comment
* don't bring in espnow package includes when feature disabled
* Formatting and removing inaccurate call mode hardcoding
* Fork ESP Now code by platform (8266 v. esp32)
* compiled html update
* Disable ESP-NOW remote by default on ESP32 until tested
* Enable ESP-NOW remote for ESP32
* Rename ESP NOW define

* it seems that NPB is very sensitive when being interrupted during LEDs driving. This change tries to avoid flash (file) writes when the strip is active.
* minor optimization: yield is completely unnecessary on ESP32 (we have a real OS).
This disables parts of the new feature that might lead to delays, so basicially there is some detection, but no protection any more.
further development needed --> audio_fastpath branch
compile with -D WLEDMM_PROTECT_SERVICE to enable full protection.
*This patch allows to compile with BOARD_HAS_PSRAM, but not set WLED_USE_PSRAM - reserved pins will be protected, and PSRAM usage will be shown in info.
* if you add `-D WLED_USE_PSRAM_JSON` then PSRAM will be used for some JSON buffers, but not for LEDs and Segments.
* pio.ini: add "-Wshadow=compatible-local" for V4 targets
* pio.ini: fix alignment for 8266 build_flags
* fix one (harmless) case of shadowed vars in MM specific code
... like the typical -C3
* Replaced a few direct Serial.printf with macros
* Always check if Serial is connected before printing (CDC sometimes hangs when trying to send/receive without connection)
