HI Martin That setting still does not trigger the interrupt as the 32Khz crystal is not oscillating, pins 2 & 3 are firmly off. I have tried just about every setting available! I think the confusion with the FC is that the SOSC uses the same pins as OSC1 & OSC2 so when they are off so is the SOSC. T...

Hi Martin Thank you for your reply. I have been waiting for some new crystals and matching caps rather than the lucky scrap bin find. 32.768 KHz crystal on pins 2 & 3 and Timer0 as your suggestion If I set the Software Oscillator Mode to EXTOSC I get oscillation on the 'scope and the PIC runs (slowl...

Hi all I am trying to set up a secondary oscillator using a 32.768 KHz xtal to give an accurate tick for a timing counter. Looking at the data sheet on page 8 pin allocation table it would seem that the SOSC shares the same block on pins 2 & 3 as the OSC1 & OSC2 which is ok as I will use the INT OSC...

Hi Martin
That is a fab idea, thanks for the introduction!

Thank you for your reply Ben I understand it better now, I have set the UART to send char and changed the LUT data format to suit and it is now sending as expected but not yet changing the font colour so I need to look at and tweak what I am sending. The display and its "bolt on" PIC based driver ar...

Early stage of a project to drive a Message Maker Led matrix display. I can display a message string, and clear it using hex sent from a byte array as it is only 10 bytes. The hex required to send default settings so I can change to font colour is much longer at 40 plus bytes so I thought I could us...

Ah thank you! A perfect answer.

I got a bit bamboozled by the sheer amount of options with selecting frequency modes, lots to learn.

This is a new PIC to me, an upgrade from my usual 16F688 so the I can make use of the PWM function. However I am unable to get the interrupt timer in the properties faster then 15Hz with a 4Mhz HS external crystal. I am looking for around 1kHz. Have I got a setting wrong somewhere? Before i get too ...
