- TomVDB 7y agoLet's not go overboard about the 1Mb claim: it's an incredibly inefficient protocol. At best, you'll be able to push 200Kbps through it, and that's for writes. Reads are much slower.
- kurthr 7y ago10 fingers at 100Hz with 4bytes each is 4kBps or 32kbps so that's not really a problem for a self contained touch screen. If you want raw data... then yes, you'll need 10Mbps or so.
