Errrr, do I detect a hint of sarcasm?
Actually it was mild exasperation. I know I shouldn't do it,
but sometimes I just give in to it. Mr. Green

But truly, the current data sheet (Rev. C) fo ...

Crystal oscillators take time to start.
PUT allows for this, not trying to run the chip, till a few mSec after the supply goes on. It is not needed for the RC oscillator which starts in only a few uS ...

First of all, sorry for the syntax. It was not a copy paste of the C file but a quick typing since I was on another computer. From all your comments, understanding there is not such a special device f ...

Hi,

I don't see a fuse to configure the oscillator. Generally, you'll use one of the
following: LP, XT, or HS. I'm not sure what happens if you don't specify
anything, but if the default is the ...

Q1.What value have you chosen for the xtal caps ?

thanks for your quick response. I´m using 22 and 30 pF

Also tried at 10.2 MHz and 7.37 MHZ without success.

This could be a hardware limitation or something missing in the settings.
I am trying to run an easy Led blinker, 250 msecs on/off, on a 12F675 with a crystal at 20 MHz without success. It works at 4 ...

I'm having troubles to get binary data thru the RS232.
Data entering the port may be any value from 0 to 255 (not only ascii chars). I need to store that data, then get it back and finally output i ...

thanks all of you for your quick response.
putc() works fine. I didn't try it before because the reference manual says the parameter should be an 8 bit character, so it`s a bit confusing...
also wha ...

I'm trying to transmit the hex values of a table (or binary values, as you prefer) to the RS232 port and, whatever I do, I get the ASCII values of the chars instead.
Example: If the value of the vari ...

thanks for your answers.
The project is running now buffering 50 bytes on a 16F628 so the 18F452 seems to be "so much" for that task.
the FM24C16 looks to be very interesting. I have to study the pr ...

I want to add RAM to a project. I need to buffer about 600 bytes so I need 1Kb of RAM and I can't find any serial (I2C) static RAM of that size, not either a vendor of the PCF8570. I want to use a PIC ...

can I do this:
setup_timer_0(RTCC_DIV_256|RTCC_INTERNAL);
setup_wdt(WDT_2304MS);
Confused

from the 16f628 data sheets
" An 8-bit counter is available as a prescaler for the Timer0 module, ...

Ttelmah, you gave an excellent description of how interrupts work but I can not understand why you say
"The time from the interrupt 'event', to actually arriving in the corresponding handler, will t ...

I need something easy to start with for the 16f628: a sample programm turning on and off an output and sending a message to the rs232 port. I'm missing something important that don't let me do any of ...
