Oscillator question (LP-mode)
Posted: Mon Aug 16, 2021 5:14 pm
In the datasheet for the 16F1827 ( http://ww1.microchip.com/downloads/en/d ... 41391d.pdf ) as from page 299, I see tables with different BAUD rates with different Xtal's. "BAUD RATES FOR ASYNCHRONOUS MODES"
I want to use a PIC that consumes as less power as possible, and then I see the 32khz XTAL configuration (LP mode) as the most power efficient..
My question is if the 32khz crystal can generate a decent 9600baud signal and a 1-wire signal for a DS18B20?
Maybe I need to make a leap to a 1Mhz, or even 4Mhz crystal but in these modes the chip consumes more energy.
How does Flowcode handle the baudrates?
Do they really mean a 32Khz or a 32.786kHz (Page 55 5.2.1.5 TIMER1 Oscillator), elsewhere in the datasheet them keep on calling it a 32Khz Xtal
And, how can I set the project options to 32khz?
