Hi All! I modified UIPEthernet for MBED/SMeshStudio. Original UIPEthernet writed by Norbert Truchsess. UIPEthernet have compatible API with Wiznet W5100 Ethernet library. I modified: - Replaced import to include, because gcc say 'import is deprecated'. - I merged martinayotte's modification (Correct s_dhcp ~40K more memory usage with STM32F MCU-s.) - Add support for STM32F, and ESP8266 MCU-s. - Moved htons,ntohs,htonl,ntohl definitions to uip.h. - Correct infinite loops. - Set the version to 1.2.0 (This version tested on ESP8266 too. Working properly. Without watchdog resets.) - Correct ESP8266 exception(28). - Add watchdog reset calls in functions for stable running on ESP8266. - Add geterevid function to get ENC28j60 chip erevid (revision information). - Change linkStatus to static for outside call. - Add functions bypass, if can't communicate with ethernet device. - Add SPI bus instabil communication detection. - Change debuging/logging. Remove individual debuging. Add global and scalable debuging feature. You can setup debuging/logging level in utility/logging.h You can use this header file in Your scetch too. Add "LogObject" define for serial logging/debuging with board specific default setting. - Add support for MBED/SMeshStudio IDE. I only compiled with SMeshStudio (STM32F103RB). Not uploaded and tested with device. I compiled with Arduino IDE and uploaded to maple mini a tested. Working properly. You can download from:https://github.com/UIPEthernet/UIPEthernet Best regards
