El.Ma. has always developed whole firmware for its devices in order to be fully indipendent and to guarantee all the services about its products; the primary aim is the manifacturing of devices which are compliant to specifics and industrial and commercial protocols.

Moreover in this project El.Ma. is developing a high-performances kernel for the entire Coldfire V4 family, that can be easily ported to PowerPC 5xxx, ARM9-ARM10-ARM11 and Microblaze.

 

Software specifications are:

• kernel with the following specs:

1. possibility to write applications in C/C++ using both free GCC (GNU) (i.e Codeblocks+GCC) or commercial compilers (Codewarrior, Green Hill, P&E etc.)

2. preemptive and cooperative multitasking with supervisor/user model

3. RAM management with optimized dynamic allocation

4. multiprocess management for execution of more applications or istances of the same application

5. events management

6. file system on Compact Flash FAT16/FAT32 compatible

7. FTP Server/Client for files transfer

8. Server/Client for read/write shared variables for SCADA through TCP/IP or CANopen

9. TCP/IP stack with protocols: IP/IP raw (fragmentable), TCP, UDP, DHCP, ICMP, DNS, Telnet, FTP, HTTP, SMTP

• I/O and remoted axis

• CANopen stack

• Devicenet stack

• ARCNET stack

• EtherCAT stack

• MODBUS TCP/IP and RS485 stack
