An auto-logging environment, as you know, generates a lot more data, and iOS devices have certain memory and speed limitations. I've concentrated a lot of effort into making curves "smarter", and eliminated the need to load curves into memory when performing past roast matching for the graph. It's all under-the-hood stuff at this point, but necessary now that the number of nodes can now grow quite large.

even my macbook pro (2.66 GHz Core i7, 8 GB RAM) struggles when running artisan with it's default settings of taking probe readings every second. artisan seems to re-draw the entire curve/screen each time it gets new values and doesn't manage to keep up if new data comes in every second. after changing the interval to read temperatures every 2 seconds it works fine now. so given that you can use core graphics instead of a sluggish generic cross platform open source library as artisan does but seeing that the cpu and memory resources under iOS are even more limited, i can imagine that those intervals need to be a bit slower. reading data every 5 to 10 seconds might still work very well though but i don't know what the limits are. problem i guess might be that you may want to support 1st and last generation iPads... so making these intervals configurable might be the way forward?

i found the full screen curve view and managed to setup a basic profile curve from scratch. how can i copy and paste an existing curve to a profile curve though? i looked but couldn't find how to do that.

cheers,

hi there,

great app! :)

i just 'found' roastmaster a few days ago and used it now for three roasts already. i really like the idea of a db driven application that can manage beans and inventories. not that i every will have huge inventories as a home roaster, but it's great to see what i have and used to have in a single place.

i'm using a huky 500 roaster which comes with two k-type thermocouples pre-installed. these are connected to an electronic thermometer which has a USB interface that i have hooked up to a macbook. for roast logging i have used Artisan now for quite a while. this has helped me a great deal of understanding the roaster and the roast process in general. so the primary differentiator in favor for roastmaster over artisan to me is the db based approach. what i find however sorely missing is the lack of automatic temperature reading. taping temperatures manually into roastmaster is quite a job and especially when things are a bit busy during start and end of a roast.

i guess it's not easy to add such a feature to an iOS based app as the available interfaces on these devices are rather restricted. a networked solution would work fine for me even if i have to use a mac/pc as data 'broadcaster' while roasting.

i tried to view some of the youtube videos that you had posted here in the forum, but youtube reports that the account has been deleted?

and some usage questions: is there a way to view a roast temperature curve as graph instead of node list? and also, can an existing curve be used as target or background profile similar to how artisan displays background profile curves?

thanks,
olaf
