DEFINE_WRITE 1 only works on PBP3 and up I think.
How do I do it on PBP 2.60C?

The way I do it now is by disable the TMR1 with the line "@ INT_DISABLE TMR1_INT"

Thank you!
I thought that DEFINE_WRITE 1 only was for the PBP "ON INTERRUPT" and not for "ASM" interrupts like DT-INTS

I talk about the WRITE


WRITE

WRITE Address,Value

Write Value to the on-chip EEPROM at the specified Address. This instruction may only be used with a PICmicro that has an on-chip EEPROM...

Hi

I write data to the EEPROM with WRITE and are also using DT-INTS TMR1, but before i execute a write I disable TMR1 with
@ INT_DISABLE TMR1_INT

Is that the correct way to do it?

I´m a...

Thanks for all the answers, I will order some parts now and start testing. :)

Maybe the ADM4850 115 kbps chip is a better choice for me then.

The optimum cable for RS-485 communication is of course a dedicated RS-485 cable, but I have read that a CAT5e is also working well and are very inexpensive, but how will a 3x0.75 untwisted cable...

Hello

Where can I find the homepage that were on these two links?
And where do I download the latest DT_INTS?

The code works perfect on a 16F886, thank you Henrik!

Anyone have a simple example of how I can do something like this but with larger numbers then 65535?

Thank you flotulopex for this thread, now my 3x16 DOGM display works perfect.:)

Did you ever get the display to work in 4 bit mode?

Hello


The PBP manual says this about ADCIN


I want a value between 0-255 depending on the voltage (0-5V) on RA2 and was trying to set the registers without success and then I just tested the...

So a N-channel FET should always have the S connected to the ground and the P-channel should always have the S connected to the positive supply?

The schematic almost works, but I had to change the D and S on the P channel FET. (see the attachment)
Can someone explain for me how the D and S should be connected for a N and P channel FET?
...

I changed my mind and I will not use the PICstart board anymore, I will do all on a protoboard.

The datasheet says this


Does that mean that I can feed +9 into RA4?
And if not why should this be avoided?

Does it look ok now?
I assume the standby current now will be 0uA when no button is pressed and the RA0 is not high?

Will this work then?
PORTB are using internal weak-pullups, and I keep RA0 high as long as I want the PIC to run.

Will this schematic work?

When u press a button the FET will switch on the 7805 and the PIC, and then I hold RA4 low as long I want the PIC to run.
The +BATT terminal is from a 9V battery and the...
