adding hints for the compiler for optimization.
In case your custom build complains about "const", just remove the keyword. based on e82f38e277, but going further :-)
* "const" class functions : function does not modify any class attributes ( --> "this" becomes const)
* __attribute__((pure)) : function return value depends only on the parameters and/or global variables. The function does not modify any global or static variables.
* __attribute__((const)) : function only examines arguments (no globals), and has no effects except the return value. This slightly more strict than "pure"
* hot: tells the compiler "this functions is called very often"
* cold: the opposite of hot
sometimes happens in debug mode.
GPIO | Assigned to | Info
--------|-----------------------|------------
i/o 1 debug output !! Conflict with debug output !! Serial TX
* getpixelcolor: attribute pure - it reads memory, but does not write
* some optimizations for SEGMENT.blur() and SEGMENT.fadeToBlackBy()
* FX.c:pp remove double calls to blur() and fade_out()
* FX.cpp: SEGMENT.setUpLeds() added to effects, to enable LED buffering (safe some time because getPixelColor does not need to access NeopixelBus)
* a few other optimizations to safe time and avoid "expensive" operations
* set I2C bus speed to 400kHz (default is 100Khz)
* a few other small optimizations and tweaks
* pio: esp32 V4 builds use "patch5" toolchain version, which contains a few bugfixes especially for memory management.
* leaving out DotStarHspi5MhzMethod, as we are still on NPB 2.6.9 for eth boards
* leaving out the index.css/index.css changes, as I'm not sure how to merge this.
@ewoudwijma we need to merge the JS and CSS parts when you are back; I'll stay with our MM version for now.
* added usermod config information (so it can be disabled)
* check that "INTERRUPT_PIN" does support interrupts (MM specific)
* expose "dmpReady" in public interface
* adjusted games usermod to switch to "simulation" in case mpu6050 is not active
Still toDo:
1. add interrupt PIN and errormessages to settings page.
2. de-alloc intPin when disabled (and disable interrupt)
3. usermod is still destroying DEBUG_PRINT macros.
4. temporarily disable MPU interrupt when onUpdateBegin(true)
- shorten oappend MM function names
- add aOpt: analog options only
- add pin 17 for esp8266 (analog pin)
- add a.pins array to show analog pins in pin dropdown
* Additional functions: isPinPWM, isPinINT
* aliases: PM_ADC1 instead of PinManagerClass::ADC1
* make getADCPin work on "classic ESP32"
--> Tested and works on 8266, ESP32 (default platform), ESP32 (V4 Platform). ESP32-S3, ESP32-S2, ESP32-C3
bool isPinTouch(int gpio); // true if gpio supports touch functions
bool isPinAnalog(int gpio); // true if gpio supports analogRead
bool isPinADC1(int gpio); // true if gpio supports analogRead, and it belongs to ADC unit 1
bool isPinADC2(int gpio); // true if gpio supports analogRead, and it belongs to ADC unit 2
#define PM_NO_PIN 255
typedef enum { ADC_none = 0, ADC1 = 1, ADC2 = 2 } AdcIdentifier;
uint8_t getADCPin(AdcIdentifier adcUnit, uint8_t adcPort); // get GPIO number for ADC unit x, channel y. 255 = no such pin
as it turns out, also on 8266 any pin can be assigned to I2C. Only SPI pins are fixed, and GPIO16 should not be used as it does not support interrupts.
* It was not possible any more to set I2C pins back to "-1", to disable I2C.
This fixes the problem.
* HW_PIN_SDA / HW_PIN_SCL may contain "-1" --> use PIN numbers directly on 8266 (I2C pins cannot be changed any way on 8266)
- show VBAT pin (if board definitely has that feature)
- some WROVER board have cross-connection between GPIO 25/27 and PIN 16/17
- experimental support for boards that have NEOPIXEL_I2C_POWER
got myself an adafruit "qt py -S2" with tinyUF2 bootloader. So I wanted to get that working. And it does work :-).
FFT time = 10ms (instead of 2ms on classic ESP32) is a very good result, also virtual USB runs much better now.
- new partition table for boards with UF2 boot (Adafruit qt py S2)
- better treatment of debug out using "USBCDC" native port
- workarounds for watchdog crashes on -S2
- Add missing but mandatory build flags for -S2 and -C3
wled.h:
- Don't use Serial directly -S2 as S2 serial driver is buggy.
- added USER_FLUSH macro
wled.cpp
- replace fluh with FLUSH
- print ArduionoOTA info (if enabled)
wled_server.cpp:
- added userlog info after file upload.
pinn_manager:
- don't show "(default)" is the PIN is actually assigned to HW drivers
- bugfix for getPinOwner()
