mga sir ask lang kung ano possible prob ng ginagwa ko program and circuit nag rrun nman po kaso meron error sa proteus
"simulation is not running in real time due to excessive cpu load" nagkaka ganito po kapag sinet ko 20mhz processor clock frequency sa proteus dun po kasi nakukuha talaga quality ng program, kpag sinet ko po ng 10mhz below medyo hindi na maganda pakinggan yung sound.

eto po program

Device = 16F628A
Xtal 20
All_Digital true
Dim loop As Byte
Symbol pin = PORTA.0
theme:
Sound pin, [50,60,70,20,85,120,83,40,70,20,50,20,70,20,90,120,90,20,98,160]
DelayMS 250
For loop = 128 To 255
Sound pin , [loop,2]
Next
Sound pin, [43,80,63,20,77,20,71,80,51,20,90,20,85,140,77,20,80,20,85,20,_

PC mo may problema, CPU dyan malamang eh CPU ng PC mo....

Looking at your circuit, ano ba yung LS1 sounder mo, Piezo o magnetic (speaker)? Kasi kung magnetic dapat meron DC isolation gaya ng non-polarized capacitor kundi maglo-load nga sa uC. Ano pa yung Q1 circuit mo?

piezo sounder po gamit ko. hindi ko po masyado gets yung circuit paano po kung magnetic sounder gamit?

May example circuit diyan sa proteus na nag emit ng sounds.

Ang piezo kasi ay parang capacitor, open circuit sa DC signal. Kaya kahit na steady Hi or Lo ang output ng micro hindi ma pull down ang V+ na pinagkakabitan ng other side ng piezo o sounder mo. Kung magnetic naman, continuous circuit ang DC signal na output ng micro kaya maaaring ma-load ang device kung naka steady Lo ang port pin at nasa V+ naman ang kabila ng speaker.

Ang piezo ay di na kailangan ang resistor (R4) to V+. R3, Q1 & R4 do not serve any purpose as in the circuit.

C828 po Q1 ano po pwede replacement na transistor d2? wala po kasi available na c828 sa proteus.

♥ ♥ Mel ♥ ♥ · « **Reply #7 on:** May 30, 2012, 04:29:40 PM »

ty po ate pwede pala i connect siya direkta sa Uc then yung isa pin sa Ground

general purpose lang naman ang C828, so 2N3904 nalang gamitin mo, mabigat talaga sa proteus kapag may analog part, kaya mas maganda padin mag simulate sa actual

Sir kung ganun po ginawa ko sa actual tpos ganun yung circuit ko ano po possible na mangyari nun? masisira po ba Uc?

Gwenda · « **Reply #10 on:** May 30, 2012, 06:14:55 PM »

What is the purpose ba ng Q1 circuit? The only thing I could think is- to reset LS1 or to discharge its pin that's connected to R4 when the uC RA0 goes Low. Is that necessary?

Simple lang .... hindi kaya isimulate ng pc mo ang proteus circuit mo running at 20Mhz. Anandar siya but not in real time kaya putol putol ang sound output.

no way you can simulate sound command in proteus

unless you have a super computer
