Greetings. As background we sell several types of datatalogger and we would like to have a Smartmedia adaptor which works with all of them. The best way of interfacing seems to be the RS232 port because it is common to all our DLs. The cards must be readable on ordinary USB adaptors. Our dataloggers wouldn't have to format the cards - just write data to them. I have not been able to find a suitable adaptor or a design for one.
It looks as though we would have to design a microcontroller circuit and write software to handle the FAT16 file format on the cards. This would be a substantial project.
What size is the task likely to be? what sort of issues would we have to deal with? Are there any ways we can save time eg by adapting an existing unit? using existing software etc?
Any advice appreciated. JC
