Electronics in Germany to have their devkit (SMT-C-T10). I have signed a NDA with them to have MXT224 protocol guide but they never send me Protocol Guide. I will try another distributor. > shouldn't this be 16/14? You are right, I already try this and test it again but this does not change anything. > something goes wrong in the initialization; the object table of the > chip doesn't match the register data fed in -- the mxt224 can be a bitch > and play dead So what can I do ? Maybe a problem with the embedded firmware that need an update (atmel_mxt_ts 0-004b: Family ID: 129 Variant ID: 1 Major.Minor.Build: 2.0.AB) When I do cat /proc/interrupts and I short-circuit /CHG to ground, number increases so low-level handling of interrupt is working. Thanks, Ga?tan Carlier.
