Have been using Richard's include for the SSD1306 (32*128) display with sucess.
I was now trying to display a single dot which would move on the display according to an X and Y coordinate variable.

Using the command GLCDDHL 0,0,1,1 works to display a single dot and for a fixed X and Y value but not if I want to use something like Xvar and Yvar.

How can I do this?

Hello :)
AI has no answer.

even at 64mhz, FREQUOUT provides very low volume, distorted audio, while SOUND, even on 4Mhz 628A chip, produces loud and clear sound.
This is not chip or hardware issue - tested on numerous 12F-16F-18F devices. This is PBP issue as it seems. Can we fix it somehow? ]]> mel PIC BASIC Pro CuriousOne https://www.picbasic.co.uk/forum/showthread.php/27116-Why-SOUND-statement-produces-loud-and-clear-sound-but-FREQOUT-does-not <![CDATA[DT interrupt problem / K40 - "Priority State Not Found"]]> https://www.picbasic.co.uk/forum/showthread.php/27115-DT-interrupt-problem-K40-quot-Priority-State-Not-Found-quot?goto=newpost Tue, 21 Apr 2026 01:07:25 GMT I'm trying to switch from an 18F25K20 to an 18F26K40, and I'm getting a compiler error (PBPX 3.1.6.4) specific to the timer interrupt definition. I'm using the interrupt include file "DT_INTS-18_3_4c.bas" as defined in this thread:

https://www.picbasic.co.uk/forum/sho...T_INTS-18_3_4c

I've tried defining the priority via the INTCON and IPR0 registers directly, modifying the original "DT_INTS-18.bas" directly based on mpgmike's writeup to customize the interrupts, and changing to a timer1 interrupt (vs timer0), but no dice. I imagine I'm overlooking something simple cause I can often be an idiot. Any help is greatly appreciated! The code for the interrupt definition code is below:

Code:

@bsf IPR0, TMR0IP 'set timer0 overflow to high priority

IPR0.5=1

INTCON.7=1

INTCON.6=1

INTCON.5=1



'----[Start High Priority Motor and PPM Read Interrupt]-------------------------

ASM

INT_LIST macro ; IntSource, Label, Type, ResetFlag?

INT_Handler TMR0_INT, _MOTOR_CONTROL, ASM, yes

endm

INT_CREATE ; Creates the interrupts 

ENDASM

'----[End High Priority Motor and PPM Read Interrupt]---------------------------
