Secondary oscillator on a PIC16F18425
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...

Re: Rs232 display driver
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...

Rs232 display driver
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...

Re: New Project interrupt timer slow
Ah thank you! A perfect answer.
I got a bit bamboozled by the sheer amount of options with selecting frequency modes, lots to learn.

New Project interrupt timer slow
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 ...
