Release 0.29.0 · ssilverman/QNEthernet

Added

Added protected access to the internal std::FILE* stream in the StdioPrint utility class.
Added more unit tests:
- test_ethernet:
  - test_server_zero_port
  - test_server_accept
  - test_server_construct_int_port
Added printf format string checking for Print-derived classes. As of this writing, Teensyduino (1.59) and other platforms don't do compiler checking for Print::printf.
Added more support for errno. Appropriate functions will set this after encountering an error.
Added tests for the Arduino-API begin(...) functions.
Added a way to utilize an externally-defined driver.
Added driver_is_mac_settable() to the driver API. This checks if the MAC address can be set.

Updated and improved PixelPusherServer example.
Call qnethernet_hal_get_system_mac_address(mac) in the unsupported driver's driver_get_system_mac(mac) implementation. This enables MAC address retrieval for more platforms when communication isn't needed; Teensy 4.0, for example.
Turned the internal MAC address into an optional and simplified the Ethernet constructor. This change should make it easier to initialze a MAC address from a custom driver.
Changed Arduino-API non-DHCP begin(...) functions to return bool.
Improved driver logic so that lwIP options can be included in the driver headers.
Improved OSCPrinter example to use the UDP data directly.
Renamed driver_set_mac_address_allowed() to driver_set_incoming_mac_address_allowed().
Changed driver_proc_input(netif) to return a pbuf*.

Fixed EthernetServer::port() to return the system-chosen port if a zero value was specified.
Fixed EthernetUDP::stop() to leave any multicast group joined when starting to listen on a multicast address.
Fixed MAC address restore if an Arduino-API non-DHCP begin(...) call fails.
Fixed EthernetClient::read() and peek() to return -1 instead of 0 when there's no internal state.
Properly initializing multicast filtering so that it happens before igmp_start(), which sets up the all-systems group.
