I am looking at building a temperature logging device.
Since I am familiar with and have the programming tools I'd like to stick with the PIC 18F family.
I have the temperature sensor part working with a PIC I have on hand.
I want to add logging so that I can take an SD chip or thumb drive and plug it into a PC for analysis.
At first I thought I could log to a thumb drive but after I looked into it, I found that the USB enabled PICs can only be a device and not a host. Is this true?
I could also write to an SD memory card. But all of the sockets I have seen are surface mount. My soldering skills might not be up to surface mount. Are there other options for SD memory sockets? But I suppose if I am going to get started on surface mount a socket is a pretty good way to do it.
One thought I had was maybe get a large capacity EEPROM and transfer the data via RS232 to the PC but that is a bit cumbersome.
Any other ideas?
