Summary of PIC16F877 ISA ETHERNET WEB SERVER PROJECT
The article describes a PIC16F877 microcontroller project functioning as an ISA Ethernet web server using a 3Com 3C509 network interface card. It implements TCP/IP protocols including ARP, ICMP, Telnet, HTTP, and UDP for features like temperature sensing via DS1302 RTC and APRS data streaming. The system supports RS-232 control, EEPROM configuration, and debug capabilities.
Parts used in the PIC16F877 ISA Ethernet Web Server:
- PIC16F877 microcontroller
- 3Com 3C509 ISA NIC
- TCP/IP protocol stack
- DS1302 RTC
- SMT 160-30 sensors
- RS-232 port
- Processor's EEPROM

ISA ETHERNET PICMICRO MICROCONTROLLER WEB SERVER
I have made Pic3Com construction (version 0.1) with idea to have a basement for PIC16F877 and Ethernet (with TCP/IP protocol) cooperation. I have choosen ISA NIC 3C509 (my favourite ethernet card) for this project, because ISA protocol is simple to implement in microprocessors.
inicialization of ISA 3c509 (3c509B) NIC NIC have to be configured for communication I/O=0x300 and Interrupt 10 address resolution protocol ARP internet protocol IP (support for default gateway included for Internet communication)
ping (ICMP Echo Request / Reply) TCP protocols TELNET (server and client) and HTTP (server, 2KB of PIC’s RAM are dedicated for html pages) UDP protocol daytime for synchronization of internal DS1302 RTC temperature measurement (up to 7) connected SMT 160-30 sensors (as a reply to appropriate Telnet protocol based request)
connect to aprsd stream with possibility to authorize and send data tracked from connected meteostation two switchable aprsd data output formats (TNC2 or UIView log) multilevel program run debug possibility control via RS-232 port configuration via processor’s EEPROM

- Which ISA NIC was chosen for this project?
The 3C509 (3c509B) NIC was selected because the ISA protocol is simple to implement in microprocessors. - What I/O address and interrupt are configured for the NIC?
The NIC must be configured with I/O=0x300 and Interrupt 10. - How much RAM is dedicated for HTML pages?
2KB of the PIC's RAM are dedicated for storing HTML pages. - Can the system measure temperature remotely?
Yes, it can measure up to 7 connected SMT 160-30 sensors via a Telnet protocol request. - Does the system support APRS data streaming?
Yes, it connects to aprsd streams with authorization options and two switchable output formats. - How is the device configured?
Configuration is handled via the processor's EEPROM. - What protocols are supported for internet communication?
It supports ARP, ICMP Echo Request/Reply, TCP, TELNET, HTTP, and UDP daytime synchronization.
