#### 0.4.0 Breaking change
|
||||
|
||||
The version 0.4.0 has breaking changes in the interface.
|
||||
The rationale is that the programming environment of the **Arduino ESP32 S3**
|
||||
board uses a remapping by means of the include file **io_pin_remap.h**.
|
||||
This file remaps the pins of several core Arduino functions.
|
||||
The remapping is implemented by #define macros and these implement "hard" text
|
||||
replacements without considering context.
|
||||
The effect is that methods from this class (and several others) which have the same
|
||||
name as those Arduino core functions will be remapped into something not working.
|
||||
|
||||
The following library functions have been renamed:
|
||||
|
||||
| old name | new name | notes |
|
||||
|:-----------------|:-------------|:--------|
|
||||
| analogRead() | read() |
|
||||
| analogWrite() | write() |
|
||||
| pinMode() | pinMode1() |
|
||||
| digitalRead() | read1() |
|
||||
| digitalWrite() | write1() |
|
||||

||||
|
||||
