Hi everyone,

The following code was run on the 12LF1822 to test its power consumption rating:

#include <12LF1822.h>
#fuses INTRC_IO, NOWDT,NOPROTECT,NOMCLR,NOBROWNOUT,NOPUT,NOIESO,NOFCMEN ...

FWIW, If you take a look at the device header file:

////////////////////////////////////////////////////////////////// UART
// Constants used in setup_uart() are:
// FALSE - Turn UART off
// T ...

Included the following code before main() to disable the EUSART:

#byte TXSTA=0x02
#byte RCSTA=0x08

The registers TXSTA and RCSTA are the registers for configuring the EUSART for the 12LF1822. ...

Hi everyone,

Still having challenges with the 12LF1822. Am trying to completely disable the EUSART - both transmit and receive.

Used setup_uart(0) and setup_uart_speed(0) but CCS C compiler (ver ...

Placed before main() the following and was able to disable the CLKOUT for the 12LF1822:

#rom 0x8007 = {0b00100110100100}.

Thanks Ttelmah.

I do apologize for omitting the details. I am using the PICKIT 3 version 01.26.05. The compiler is CCS C-compiler. Couldn't find the version. I am using the MPLAB IDE version 8.50. ...

Hi everyone,

I just got the 12LF1822 and attempting to run a working program from the 12F683. Noticed PIN 4 - CLKOUT is outputting fosc/4 despite the fact that I had disabled it in the fuses direc ...

Thanks.

Tried the second option using the voltage divider and the peak detector. As you rightly stated, I encoountered spikes from the ac signal.
Will now include a low pass filter before the peak ...

Hi everyone,

Progressing further with learning to use the 12F683 analogue comparator function, would appreciate suggestions on how I can use this to monitor an input AC voltage signal ~ 4V peak-to- ...

Many thanks for the example source code. It worked.

Many thanks for the example program code.

Will try it out now.

Hi,

I would like to monitor the output when an analogue signal goes above 1V compared with the internal voltage reference.

Could anyone kindly provide the steps to configure/setup the analogue c ...

Many thanks once again for the clarification.
I will now resort to setting a long delay immediately on power-up of the 12F683 - time enough for the capacitor to charge with minimal loading from the P ...

Just checked through the 2007 12F683 data sheet. On page 87, Figure 12-3 shows that the brownout causes a positive-going rise in the internal reset when there is a dip below Vdd, lower than VBOR. It d ...
