Greetings!

I've done googling around to look for something similar, but all of the information is way out of what I can understand. Appreciate if some one can provide me some guidance on this...

Thanks for the guide. I have clearer idea now. Sorry for OVERDOING it. But at least Mr.Skimask and Mr.Acetronics is willing to help me out. Thanks.

Not that I can't think out of the box, but I've asked around and tried whatever is possible, to display counting in LCD, not to display in LCD, to display only the final value, etc, but i still can't...

Is that mean the culprit for unable to get 1ms interval timer is the LCD display? What is I just make it display the final value upon stop button is pressed? Can this solve the problem?

The additional line of code after the clear overflow flag is to test the timer whether the timing is accurate or not. Let's say of ms can't be seen, but at least for the seconds can be seen...

Yeah, I did make TMR1H = $FC, TMR1L=$18, which is obtained from 65536-1000. But the timer does not give me 1ms interval. I do not know what is wrong. Below is my program:

'MAIN PROGRAM...

I am using 4MHZ, 16F877a, Timer1, setting TMR1H = $00 and TMR1L = $00. Tried to activate the timer as free running timer. Previously used to capture the timer time from 0 - 65536 microseconds (full...

I use Timer1 as a free running timer, using 4Mhz clock and 16F877A MCU. I do not know how to extend the timer range as it is from 0 to 65536 microsecond using 4Mhz clock.

Can anyone teach me to...

Ok, I will change to Start the timer before doing anything on the LCD. I see, from the explanation, may I know the timer rolloever every 65536 microsecond or 65.536 microsecond? Let's say is it as...

I rewrite a new program to activate Timer1 as free-running timer. I take the TMR1L and TMR1H value directly, and obtain a new result by:
Result = TMR1H*256+TMR1L

May I know, is the RESULT I get...

I modified the Olympic Timer program, by replacing the:
TMR1RunOn.HighByte= $FC
TMR1RunOn.LowByte=$18

and deleted the TMR1RunOn=TMR1Preset+TMR1RunOn, to directly load the TIMER1 preset value...

thanks mister_e, this will help me in experimenting the 1ms interval polling. Is there anyone can help me on how to get 1ms interval by polling method for timer1?

Is there anyway to add assembly language to the codes in PicBasic Pro? Can anyone guide me to do polling using timer 1 in 1ms interval?

Anyone can help me on this?

I only made changes to the pre-load value, LCDOUT command to display up to 3 digits and the tickcount interrupt handler, where I put in the new:

Tickcount changes:
If RunningFlag=1 then ...

Method 1 is sufficient to complete my project, as it is possible to capture display the time in milliseconds.

I am facing a problem here of which, I do not know how to calculate the require timer...

Perhaps capture the time in microseconds is impossible to do so since no reply from anyone. Anyhow, from the Olympic Timer and Automatic Clock provided by Melanie and Darren, both of the project...

I tried on the OLYMPIC TIMER project provided by Melanie in the Sample Code Section, and that is indeed a good one. But, I am currently working on a project which requires me to capture the time in...

No matter how I try before this, it just can't work, with a few additional line of codes provided by you, everything happen perfectly, it's miracle! Meaning that the cause of the failure is I didn't...

Hi, I am new to PIC and was working on a school project. The problem is, I am unable to make my LCD work. My LCD model is RT1602C. Below is my codes. Can any expert out there to let me know what is...
