C6 experiments by softhack007 · Pull Request #138 · MoonModules/WLED-MM

This is a first, very experimental support for the ESP32-C6 chip. It compiles, but nothing tested on the hardware yet.

Its intended for WLED/MM core developers, to understand better where the differences are.
If you don't consider yourself a "core developer", then please ignore this PR and do something meaningful 😛

⚠️ no PWM support yet - so you can't use analog LEDs
⚠️ NeoPixelBus drivers are running in "BitBang" mode, so don't attach more than just a handful of addressable LEDs.
⚠️ Audioreadctive not supported yet, due to massive changes in I2S API

Currently some libraries are not compiling with Arduino Core 3.0.x, so i've forked these and made a few minimal patches to allow compiling. Also I had to make a "no FastLED" version of FastLED, because the clockless RMT driver of fastLED is causing crashes at startup - even when all outputs are managed by NeoPixelBus -> E (423) rmt(legacy): CONFLICT! driver_ng is not allowed to be used with the legacy driver.

due to Arduino 3.0.1, a few updated libraries are required: * Tasmota Platform - official platfomio lacks arduino support for C6 * FastLED (latest + C6 build patches) * AsyncTCP (latest + C6 build patches) * AsyncWebServer (latest + C6 build patches) * NeoPixelBus (lastest)

ledc drivers have a different API in Arduino V3.0.1. --> temporarily disable PWM support for C6, until we find the time to adopt to the new API.

currently NPB only support BitBang drivers for -C6. This patch re-maps all RMT driver calls to BitBang.

The ESP32-C6 chip features 31 physical GPIO pins (GPIO0 ~ GPIO30). Each pin can be used as a general-purpose I/O, or to be connected to an internal peripheral signal. restrictions: ----------------- SPI0/1: GPIO24 ~ GPIO30 are usually used for SPI flash and not recommended for other uses. USB-JTAG: GPIO12 and GPIO13 are used by USB-JTAG by default. If they are reconfigured to operate as normal GPIOs, USB-JTAG functionality will be disabled. Strapping pin: GPIO4, GPIO5, GPIO8, GPIO9, and GPIO15 are strapping pins. For more information, please refer to datasheet. For chip variants with an SiP flash built in, GPIO24 ~ GPIO30 are dedicated to connecting the SiP flash; GPIO10 ~ GPIO11 are not led out to any chip pins; therefore, only the remaining 22 GPIO pins are available. For chip variants without an in-package flash, GPIO14 is not led out to any chip pins.

adding `#if defined(CONFIG_IDF_TARGET_ESP32C6)` whenever C3 was mentioned

lessons learned: one doesn't simply `#if defined(ESP_IDF_VERSION) && ESP_IDF_VERSION >= ESP_IDF_VERSION_VAL(5, 0, 0)` ;-P

* more debug output * added my own fork of FastLED ( looks like more bugs to solve ....)

…into C6_experimental

... instead of reduced Tasmota-Arduino

Update: its still mysterious, however something to do with RMT 🤔

E (423) rmt(legacy): CONFLICT! driver_ng is not allowed to be used with the legacy driver

Rebooting...

Edit: in practice any firmware that still uses the "old" RMT driver might crash, because arduino-esp32 v3.0.x itself links in the new RMT driver -> legacy driver conflict.
Looks like a workaround - in some cases - is to make sure that RGB_BUILTIN is not defined.

softhack007 · 2024-06-14T11:33:12Z

its booting into WLED 🥳 🚀
Seems that FastLED was causing all the troubles -> -DFASTLED_NO_FASTLED did the trick.

ESPHome seem to have their own version of AsynTCP and AsyncWebServer, maintained regularly. Might be worth to give them a try on -C6.

ewoudwijma · 2024-06-17T21:48:48Z

@softhack007 , didn’t WLED AC updated their version of espasyncwebserved recently ? Maybe the same as esphime uses?

softhack007 · 2024-06-24T08:52:39Z

Espressif has declared commonly used network API's as "deprecated" - WiFiClient, WiFiServer, WiFiUdp and WiFiClientSecure
There are replacements, however with more differences than just new names 😢 espressif/arduino-esp32@ad1de0b

another area where lots of rework will be needed, just to keep existing features working on new chips like -C6.
I'm not amused.

softhack007 · 2024-06-24T10:16:33Z

Known problem: IP address is always shown as "0.0.0.0" in info page -> might also cause some connection problems in WS or Web UI.

NetworkClient class in ESP32 Arduino Core v3.0.1 always returns IPAddress(0,0,0,0) via localIP() method (might get fixed in core v3.0.2)

The mentioned PR is just in the master branch at this time.

It will be available in 3.0.3.
But it can be applied to any 3.0.x version for testing.

@SuGlider thanks for the good help. 👍 I can confirm the fix works, no more crashes at startup 🥇
It actually took me a bit of time to get back to this project - sorry for letting you wait.

bus manager: ledc (PWM) driver disabled for -C6

931788f

ledc drivers have a different API in Arduino V3.0.1. --> temporarily disable PWM support for C6, until we find the time to adopt to the new API.

added WLED_NO_RMT_PIXELBUS for -C6

b19902b

currently NPB only support BitBang drivers for -C6. This patch re-maps all RMT driver calls to BitBang.

workaround for network class naming conflict on -C6

-C6: rtc_get_reset_reason --> esp_rom_get_reset_reason()

several places where -C6 should be treated like -C3
