Re: SPWM (Sinusoidal Pulse Width Modulation) Programmer Needed

I was trying to play around with the code trying to see if I can personally change the code to flow code and this is what I came up with but don't even know if it works because I couldn't compile it and test in proteus coz I think I exceeded the space on the MCU.But anyways, have a look at the code ...

Re: SPWM (Sinusoidal Pulse Width Modulation) Programmer Needed

Since most Microcontrollers don't have the ECCP but have the CCP instead, its better to use the PDF below to make it easy when choosing an MCU.Take note, in this PDF, he first shows the code with the use of the ECCP at the top of the page then after goes ahead and give you the CCP code showing all t...

Re: SPWM (Sinusoidal Pulse Width Modulation) Programmer Needed

For easy understanding please use exactly the same variables in flowcode as the guy used in his code in mikroC.Thanks for you time friend.

Re: PullUp/ PullDown Resistors

Thanks Steve, but 0 = PORTB pull-ups are enabled by individual port latch values. How do we write it if I want to enable pull_up resistor only for like port B2 ?

PullUp/ PullDown Resistors

Hi everyone hope u are OK, my question today is how do we enable internal pull-up resistors and pull-down resistors in a pic microcontroller like the PIC18F442 ?

SPWM (Sinusoidal Pulse Width Modulation) Programmer Needed

Hi am looking for someone with good pic microcontroller C coding knowledge to code for me SPWM using PIC18F442, this should have an ac output feedback for output voltage control with an output frequency of 50Hz, i would like two complete flowcharts one using the ECCP module and the other using the C...

Re: Pure Sine Wave Inverter

I can see many downloads of this mnf inverter code, has anyone tried changing this to a PIC , has anyone built this already to share the ups en downs if any?

Re: Pure hard meat Sine Wave Inverter

Thanks mr mnf for your time in this but i think as for me, this is becoming hard meat to tear down, and i have only FC8, i don't know if i can do a direct shift to FC8 with 18F442 and a 20mhz crystal.Question, which pins is your spwm on?

Re: Pure Sine Wave Inverter

Thanks mnf for the link, but we don't need to buy one when we already have one for free in the link below, the guy used PIC16F684 I think this has enough info for a pro like you to figure things out and make it work in flowcode.

Re: Pure Sine Wave Inverter

Am kindly asking if you get some time you help change this to 18F442 as it's so advanced for me to know how to change it as a beginner.Another thing I tried looking for the sine look-up table in your code but couldn't find it,how did you implement your SPWM without this sine- look up table.

Is this:- FCV_TMR1 = (TMR1H << 8) | TMR1L; same as

FCV_TMR1 = (TMR1H << 8) + TMR1L;
