Hello,
these days I am using Flowcode with pic 18F46K20 and, although in simulation it works as expected, not as much in the real world; instead the circuit works correctly with the 18F46K22. The problem that occurs is a non-operation of what is connected to PIN RA4 (DHT22) and what I suspect is that the settings of the project chip seem somewhat different from the norm ....
Thanks

Hello,

Have you started with something simple like this to confirm the configuration of the new chip?

Hi Benj,
thanks for reply; there is not a problem with clock but only when use RA4 with DHT22 (no communication) and only changing chip and relative setting all work ok with same program. I suspect a problem because windows setting appear a little strange respect chip of same family.
I made some test next week....

Hi Benj,
i can confirm that there is a problem with 18F46k20 problably setting oscillator (PLL).

Hello,

Do you think the problem is hardware related or do you want me to investigate to check the Flowcode config settings are correct for the device?

Hi Benj,
problem is related to oscillator setting 18F46K20 in Flowcode when used PLLx4 (hardware is in production and ok); this is also confirmed by importing hex file in several software device programming that show not correct oscillator setting.
If You can investing on this problem and save my life
