Hi,
So I'm playing with DT's instant interrupts and even started to modify the T1CON register to adjust the prescaler. I'm using the 16F628A running at 4Mhz so it looks like the maximum time I can...

Thanks Bruce!

I'm not using MPLAB just MPASM under MicroCode studio.

Before when working in PM I preset my fuses like this:


@ DEVICE PIC16F628A, HS_OSC, WDT_OFF, LVP_OFF, PWRT_OFF, PROTECT_OFF, BOD_OFF


Now in MPASM I'm getting "Overwriting previous address...

Works!!!

Quick question, why are you enabling the interrupts after the ASM-ENDASM not inside?



ASM
INT_LIST macro ; IntSource, Label, Type, ResetFlag?
INT_Handler ...

Oh no.
I was hoping to use that in my gate opener and run it from a battery, that's why I need the pic to sleep for 99.9% of the time.

In case you do find your version, please let me know. Till...

DT instant interrupts with mister_e keypad (16F628A)

I'm new to interrupts and tried DT instant interrupts by Darrel Taylor (thanks Darrel). The blinky works great with the INT_INT.

I want for...

Thanks Bruce that did it!
By the way, your website is very informative.

Works now.
I changed the RC values of my switch debouncing and changed the interrupt rutine from:


toggle led1

to


low LED1

It did toggle with my previous setup with switch on B.0 using INT_INT so it should toggle now on B.5 using RBC_INT as well.

When I press the switch I get 2.2V on the led

I think the problem is...

16F628A. I moved the switch to RB.5, now my led dims but doesn't turn off when push button is pressed.

Hi,
I'm very new to the interrupts but I came across Darrel Taylor's instant interrupts and wanted to give it a try. So I tried his program to toggle the led with no problems (thanks Darrel). A...

Yeah, just read section 8,
Thanks mackrackit

IT is, that's it then.
So PBP is the compiler and MPASM the assembler right? Not sure what is the difference. I thought the compiler translated source into .hex file. What does the assembler do then?

Installed MPLAB 8.1
In MCS, under View - Compile and Program Options - Click the Assembler tab.
There is a check box there -- Use MPASM ---
Click find Automatically. FOUND.


Is that it, how...

Thanks, I'm using 16F628A but I think I still have to use MPASM for Darryl's instant interrupts. Is that correct?

I decided to start playing with the interrupts and came across Darrel Taylor "Instant interrupts" includes and wanted to try them. However they call for MPASM and I've never used it before (all I...

Hi,
1. Tried BAUD CON 6 (instead of 2)..... no go
2. The crystal on the EDE702 has two 22pF caps going to ground
3. Haven't tried a crystal for the Pic (sender) but it's a '628A

Will make the...

mackrackit,
I didn't draw a schematic, just used/modified the one from the EDE702 datasheet. I'm attaching both the datasheet and a simplified schematic.
Note the schematic shows line coming from...

Hi Alain,
I did use the search and found the topic you show along with 5 other topics. I also used the datasheet that came with the EDE702. Hooked everything up and tripple-checked it. (Maybe it's...

Hi,
I've been looking at creating a serial LCD for a while and came across an EDE702 - Serial to LCD Interface IC by Elabinc:
