Hi Seb,
The library adc_clock.jal is OK (I think). But as I wrote in my msg to
Toon the application program should specify ADC_TAD_MIN when the actual
minimum value for the chip is lower than the default of 1.6 us,
especially when running at 48 MHz.
I assume you do that in your program, otherwise you should get a warning.
Regards Rob.

so, do we need to work on this to make the lib more generic ? i used adc
recently with 18f4550 (jaluino) running @48mhz, results via usb serial,
no troubles.

Log: Added specification of actual value (0.8 us) for minimum Tad
(ADC_TAD_MIN = 8) for 18f4550, since the default value (1.6 us)
is too high with a clock speed of 48 MHz and would cause Frc being used.
