Hi all,
SPi is not a standard protocol...So to check weather all 8 bits of data has been sent to slave is to check SSPIF bit in cASE OF pic MICROCONTROLLER or buffer full status register...
HI friends i am having 2+ yrs of experience in micro controller programing for UPS application.Now i want to learn CAN,I2C,MSSP protocols so that complete pic micro controller i can learn.
Till now i have used ADC,TIMERS,CCP modules,Comparators, and now i want to learn other modules like...
I havent used PI equation.With PI equation i m getting those notches.so i removed PI and kept only P controller for this what i have done is i have sensed output voltage for every 1 milli second for complete half cycle and took the average and calculated error.IF that error is more than 5 volts...
HI friends
I m working on pic 16f917 micro controller .My project is to display battery back up on 3 bit LCD.I know the AH of the battery and by dividing AH with current i will get backup time.I am getting backup time in real numbers,but microcontroller is not able to hold real...
Hello friends
I developed single phase sinewave inverter usin PIC 16F886 micro controller.I have used sinusoidal PWM technique to generate Sinusoidal pulses.I am getting sinewave at out of transformer this sinewave is maintaining at buld loads very nicely and aslo voltage is...
In lcdcmd.h may contains the commands to LCD, like clear LCD screen,position the cursor,write to LCD like that.....
and in LCD.h contains intialisation of LCD ports like using 8 bit data segments or 4 bit data segments. According to ur sample code make these header file which include commands...
Hi friends,
I want to learn real time operating systems can any one tell me about this ang give guide lines for me to study.and also give me website links
Hello itaig,
I tried but its the same not maintaining the sinewave
Added after 4 hours 44 minutes:
HI again i am posting the code which is corrected but even the waveshape is changing please correct it
#include <pic.h>
#define ki 54
#define kp 32
int...
Thank you itaig,Here i am putting my waveform please tell me wat to do.....
i kept waveform for noload,40W bulb load,100W buld load,160W load.At no load it is sinewave but as i am loading its shape is changing help me to solve this problem .....
Hello itaig,
Thank you for responding to me.Now i can able to remove notches in my waveform but the at present problem is My wave shape is not maintaining sinewave when i am putting load.Our output rating is 200 VA inverter.can you help me how to maintain sine wave shape ..............
Thank...
what is microcontroller based sine wave inverter
THank you for responding sir,
Actually i got stuck in controlling the voltage of sinusoidal inverter and also wave shape is changing to square wave when i put loads.Its shape is changing and also voltage is increasing can you help me in solving...
How to calculate modulation index when i am using micro controller based sinusoidal PWM.Please tell me how to find this even i too want to know...........
Hi friends i am working on sine wave off line ups.I have written the code i am sine wave at no load as i am loading the inverter its shape is changing to square wave at 60 W bulb load initially its shape is changed to "D-shape" as i am loading the inverter it is complety going to square wave.I...
