hai all,
iam sanjay from india [moderator action: removed private email address] .... for the final software
using dspic 30f2010 and another version dspic33fj16gs504.(i am the person sold the technology to many African countries.. any body want full auto solar i2c based solar power utility pure...
which compiler? which version?...a lot of header files are there in internet..you can use it customized.if you want a 2 wire lcd,in ccs or in c30 i can post it here..
sir,
the code part i shared here is to get some idea about pwm H bridge init and manual smapling of adc over sinewave and sinetable pop-up using modulate function. and the commercial part is not added here,only with an intention that, while i start doing this concept,i dont get any...
hai,
after a lot of requests from the readers side, i am posting the sine wave ups source code written in mplab c-30 here.. this product is widely marketed by 2 persons in my country. as i am not a business man, i can share my know how to all without any charge. the another versions of these...
HAI anand,
iam at hykon (tsr) now,doing r&d here, i want to that to debug mode of pickit 3, i am not able to do the debug, are you in trissur now?..long back we communicated regarding glcd..
hai all...
anybody can help adc problem on dspic30f2010?
iam making a sinewave using mpwm and with a timer1 isr of 200us. in this proj, i want to take voltage of mains in and ups out.
both signals are offset based sine.say 2.5 v.+....2.5v--, when iam averaging the adc results within 10 cycles...
hai everybody...
i solved todays problem..._FBORPOR(PBOR_OFF & PWRT_OFF & MCLR_EN);
here i didnot mensioned the pwm pulse start polarity..now i reversed it ...& working ok..frequency is 55.8 hz!...and peak-peak is 144 v!..how can i solve?
sir,
i got an idea to make the sinewave perfectly and i checked it also...4 channels are smooth and nice..but you pls check the attached circuit, iam getting short circuit effect when i put a dead band in DTCON reg!. in my driver section my pic should provide a high impidence mode ! no bit...
hai sir,
i want a 180 degree phase shift in between pwm1 and 2 channels, how can it possible? and i want to load 64 sine table entry's in 10ms , iam having a pwm interrupt of 125us, so iam updating my pdc1 and pdc2(180` phase shift)
duty cycle resistors at 125us interval. but 64X125=8000us, i...
Hai friends,
i made the software and checked with transformer in bridge arm, sine wave is there, but the waves are not rounded edge,,,,if iam reducing the sec/div of scope, it seems to be as triangular wave..here iam attaching the dspic pwm isr,
const int sin_table[64]= { 0...
hai friends,
i have a ups board using dspic 30f2010, i know that this chip have a mpwm and can be used as complimentary.
such 2 pwm, if we starting with a period of (say 100us), and we start module, we can see the wave foam both are starting together...here i want to start the second ch pwm...
hai ... dears
anybody is trying to do the sinewave ups using the dspic30f2010, they can use the flexible lcd driver for the project. this file is converted by me from ccsc to mplab c30...
enjoy it..
