Blinker for 16F18446 - OSC settings and PORT addressing

Hi there,

Did anyone already make a "blinker" for 16F18446? Mine won't work at all :confused:

This device supports PPS (Peripheral Pin Select Module) and I this is new to me. Is there any captcha here?

I also don't get the oscillator configuration. This device appearently uses PLL as oscillator. But how do I configure it to have kind of 4 or 8 MHz internal oscillator?

The DS is (again) hard to understand....

Code:

you won't get far blinking pin latb.6 when its defined as an analog input

i assume you are not using a xtal osc

this will do it ,i think [ untested]

for osc=8mhz
// HFFRQ 8_MHz; OSCFRQ = 3;

Replace // with ' or ;

Guess what: it's blinking now!

Thanks a lot (again).

Yes, I had to replace // by '

These chips (with PPS registers) need more care to setup correctly. But are very versatile...
