First of all, be patient with my english. I would like to contribute a generic userspace "modbus to hal" component, AKA mb2hal.
It is based on (totally rewritten) Les Newell's code http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ContributedComponents#Generic_compo nent_with_support_for_multiple_clients_Les_Newell_flavor and a little bit on VF-S11 VFD code http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ContributedComponents#Toshiba_VF_S1 1_VFD_driver_vfs11_vfd. Some characteristics: - Does not need libmodbus libraries. - It uses functions of src/hal/user_comps/modbus.c - Support multiple serial ports, multiple IPs and multiple modbus device addresses, each one with his own set of configurable transactions. - One thread for each link (serial or TCP), so there is no inter-links waitings (most notorious in serial lines). - Maximum frecuency rate configuration for each transaction is posible. - Configurable HAL pin options (pin names, int or float type, raw or with offset+scale parameters, invert bit) - INI file debug is posible. - Independent debug level for each Modbus transaction is posible. - Totally configurable by INI text file. Right now i am using it with a TCP remote I/O device and a serial RS232 drive. I would like to know if it could be accepted as a contribution and how is the process of accepting it. If it so, I would have to polish the code a bit (Coding Style Guide, Developer manual).
