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)
platformio
- create _all entries (wip)
- set FLD_PIN_SCL to -1 (use global)
4ld
- one bug fix and errorMessage improvements
const.h
- comments
wled.h
- do not use the I2CSDAPIN vars but HW_PIN_SDA instead
I was wondering why sometimes the new MCUs still work better in Arduino IDE, so compared our build flags to what is used in Arduino IDE:
-S2 always has -DARDUINO_USB_MODE=0
-C3 always has -DARDUINO_USB_MODE=1
-S3 supports all possible modes
- 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()
* set.cpp: reject non-ADC pins as analog button pins (bugfix)
* pinmanager:
record conflicts
added getOwnerText(PinOwner tag) and getPinConflicts(int gpio)
