Re: FSK demodulator in firmware

there are some good ideas here

Re: FSK demodulator in firmware

Plenty fast, I'd say.
At 32MHz an instruction cycle is 125ns. That's ~1250 cycles between zero crossings.

I'm not trying to interpret/decode the data, just demodulate the signal.
Every other...

Re: serial LCD 1602 Backpack using PIC16F690 for Hitach HD44780

edited BaudR var word : baudr = 3313 and TRISA = 111110

1st receiving random characters
2nd normal

what could be done to avoid the first
thanks.

Re: FSK demodulator in firmware

Although it is a low frequency, still a zero cross happens every 156.2 usec for the 3.2KHz signal.

Will the pic be fast enough to process that signal? I am sure ZCD and timers will be enough, but...

FSK demodulator in firmware

I have what looks to be a 1.6/3.2kHz FSK signal that I'd like to demodulate to a bitstream using a suitable PIC.
It's a two wire system with bursts of the FSK signal riding on top of the DC supply,...

Re: serial LCD 1602 Backpack using PIC16F690 for Hitach HD44780

when testing baud rate, usualy I start at 300 and up

when it stopped working then I set pace = 1

and re-start from the last baud rate tested.

16F690 Xtal 20Mhz

set pace to 1

Re: serial LCD 1602 Backpack using PIC16F690 for Hitach HD44780

I only tested at 19200 and the Backlight works OK.

But text, could not send up to this moment.

WIll try different Baud Rate. Though I test on a PIC16F1827 at 32MHz.

Re: serial LCD 1602 Backpack using PIC16F690 for Hitach HD44780

My code honours the timing as specified by the lcd defines , timing that most lcd displays need esp the cheapest and oldest examples of them.
If you send data at a rate that exceeds the specified...
