Ok, I got the touchscreen to work (with only the ".freq=1850000,"
modification) :
here are the modules required (loaded by hand for now) :
Module Size Used by
ads7846_adc_ssp 3912 0
ts_adc_debounce 4000 0
aximx50_ts 2400 0
ts_calibrate gives then some not-so-bad results.
However, it is still unsufficient to be used "as is".
To be continued...
