HI Group, I have the following line in C that I need to port in MikroBasic if(phase > 0 && phase <= (dim_level >> 1)) { and so far I have ported it to this : Which isn't working obviously if (phase >0) AND phase <= (dim_level >>1) then can anybody tell me the right synthax ? Or what am I doing wrong...

Thank you for all your help.

Dani your xor version is working . Again thank you , now it all makes sense.

OK thanks for the input . But none of the examples you gave me seems to work for only one bit. So here is my ridiculously long code that works . Any possible shorter variant ? if Button(PORTB, 0, 1, 1) then oldstate = 255 end if if oldstate and Button(PORTB, 0, 1, 0) then flag1 = not flag1 if flag1>...

Hi , I have a relay that I would like to switch on button release. But the problem is my not operator . I have defined the relay with symbol. I simply would like to change state of PORTB.4 or in my case relayA. Allthough it turns it on the first time it never turns it off. What am I doing wrong here...

I was curious to if this project has ever been accomplished ?
Cause I would like to design and experiment with SDRAM on a similar project . This would be with a dsPIC30F5013 or dsPIC30F6014A.

Is VISTA-64 still not working ? With MikroE products

Ohh I 'm sorry then Janni :D . Of course you're right about the clocking and RBInterrupt ! I 'll get rid off the interrupt routine right away and take the easy way out . Which is: I just read all the buttons and compare them if they changed. :D And not messing with the RB interrupt . Thank you Csaba

true, that wouldn't work like that!

You mean that the serial output line of 74HC165 changes state whenever the parallel input lines change state? Without clocking in the buffer? I'll have to read the datasheet then...

still ,no need for sarcasm here.

Thanks for your help , Janni.

Janni, The clk and sl pins are in the lower nybble of PORTB and therefore not affecting the change on PORTB. Only when dtin PORT RB4 has changed from high to low. And only then the two bytes are being clocked it. Freeing up the processor for other stuff. But during that time the RBIE Interrupt is di...

Hi everybody, I have cleaned up my messy code and commented it. I also put something together on my website explaining the use of shift register and rotary encoder and what I was working on. The video explains a lot more than my written words. I tend to write very confusing, when in a hurry . And I ...

A trick for fully decoding the A and B signals is to store the previous state of A and B, then calculate A xor old B and B xor old A. This gives 0,0 or 1,1 for stationary and 1,0 for CW, 0,1 for CCW I think

do you have some snippets of code where you could demonstrate this ?

Thanks XOR for the link to the document. It seems to work now. Apparently when I save PORTB to a variable j for instance. And write it back before I clear the rbif flag it works. sub procedure interrupt() if testbit(intcon,rbif)= 1 then j=PORTB .... ISR code end if PORTB=j intcon.rbif=0 end sub And ...

Here is what I read : bit 0 RBIF: RB Port Change Interrupt Flag bit 1 = At least one of the RB7:RB4 pins changed state (must be cleared in software) 0 = None of the RB7:RB4 pins have changed state Note: A mismatch condition will continue to set this bit. Reading PORTB will end the mismatch condition...

I have modified my code to this now. I am using a PIC 18F452@10MHz. I have read that we need to read PORTB in order to clear RBIF in the datasheet of the 18F452 page 75 "mismatch condition...".And then read it again on microchips page in a thread. The RBIF gets set again or something I don't underts...

Ok I searched the internet ,read datasheets and erratas. And kind of understand that there is a 18Fxx RBIF clearing bug. I have a code where I read PORTB into j then clear the INTCON.RBIF and read PORTB again. But still I get one shot of an interrupt and never again. How does anybody else has this p...
