* add commitNonVolatileMemory overload to batch write chars n times to flash
* changed uint8_t getEepromBuffer(uint16_t size) to uint8_t getEepromBuffer(uint32_t size) to allow eeprom > 65k
* reworked PR #230
* Add defines for LED, button and serial port
To make supporting different board layouts easier, this introduces some new defines:
For all platforms:
- `KNX_LED` - the programming LED, defaults to `LED_BUILTIN`
- `KNX_BUTTON` - the programming button, defaults to `0`
For Arduino platforms:
- `KNX_DEBUG_SERIAL` - the serial port that is used for debugging, defaults to `Serial`
- `KNX_SERIAL` - the serial port used for communication with the TPUART, default depends on platform
* GD32 flash workaround
Addressing #181
At least some GD32 devices seem to require unlocking the flash twice. As the unlock function exits with `HAL_OK` if the flash is already unlocked, STM32 devices can run the same code without issues.
* Add H8I8O and H8C09 configurations to knx-demo
Addressing #181
These configurations both serve as examples for the use of these boards and other custom boards that don't use the standard pinout.
* Add STM32 unlock target
This copies the brute force unlock approach by @pavkriz into a custom target. With this commit, it is possible to automatically unlock e.g. a H8I8O board without leaving the PlatformIO IDE.
See #181
* generate unique serial number (#90)
* see https://github.com/ricaun/ArduinoUniqueID
* calculated from ESP.getEfuseMac() on ESP32
* ESP.getChipId() on ESP8266
* SERIAL_NUMBER_WORD_0-3 on SAMD
* HAL_GetUIDw0-2() on STM32
* defaults to 0x01020304 on other platforms
* fix variable name for ESP platform
* another fix variable name for ESP platform (need more coffee...)
* Add KNX_NO_DEFAULT_UART to avoid default uart assignation for ArduinoPlatforms and derivatives, with associated defines (HWSERIAL_NONE for stm32) to recover RAM from unused RX/TX buffers
Remove ArduinoPlatform(HardwareSerial* knxSerial) constructor, seems not useable by KnxFacade
* Restore ArduinoPlatform::ArduinoPlatform(HardwareSerial* knxSerial) constructor
* revert xxxPlatform(HardwareSerial* s) constructors
* Refactored the knx_facade a bit to make the auto-building of the global knx object and the buttonUp() ISR function opt-in. Also added the ability to quite easily attach another serial (in this case tested with Serial2 of an ESP32).
* Added visual studio code temp files to .gitignore
* Fix for missing build flag for WifiManager in ESP32_ip demo
* Added example in which we DIY build the KNX object and use ESP32's second UART to connect so that you can debug with the first one that's connected to USB.
* Minor platform cleanups to remove compilation warnings.
* ESP32 can't handle the defaulted 8192 byte EPROM. Next to that I needed to begin() the eprom lib in my setup() to get it to work and that requires knowing how much memory KNX will use. This fix makes the default more conservative and moves it's definition to the .h file so that other files can always use it as well.
* After comments from thelsing, inverted the logic. The default global knx object is now opt-out by defining KNX_NO_AUTOMATIC_GLOBAL_INSTANCE. See the knx-demo-diy project for an example.
Minor syntactic cleanups.
* Removed hardwareserial from facade (detail which was not needed)
Placed facade constructors together
Minor syntactic cleanup
* Fixed knx-cc1310 where own button routine was calling now private internal knx facade variable.
Renamed files in knx-demo-diy
Minor syntactic stuff
* Added gitattributes for binary knxprod files
* added overload to platform constructors for custom HardwareSerial-object
* added setter/getter setUart & getUart
* set Serial1 as default UART for ESP32
