need assembly code for sine wave using enhanced pwm

[biswajitdas49]

hi everybody,
i need a assembly code for generating sine-wave using enhanced pwm in pic16f1936.
anybody help me!!!!:-(

hi biswajitdas sine wave can not be generated by controller but you can get idea from this circuit

hi zia!

can u elaborate me how to generate sine-wave by using ccp module(enhanced pwm mode) in the step by step process,also the flow chart

dear biswa check the detail of uc and uc working. and u have to use h bridge so left ccp use other pin to create wave

actually zia,I don't understand how to vary the PWM duty cycle continuously by using look-up table to create sinewave.currently I using pic16f1936, ccp1 enhanced pwm mode for pwm pulse,timer2 for pwm period,Fosc=16Mhz.I just want to know that do u have any assembly code for this or any idea that I can change the PWM duty cycle continuously by using look-up table.

THANKS FOR REPLY!!!!!!!

if u have any lookup table then give me i will create it for u in mikroc on which file can converted to assemble by 'A' option.

Hello zia, do you know how to generate soft ware pwm? and if I have a LUT of sine wave how can you generate it using ccp module of pic.

send me lookup table i will try for u but will be in c
