i use AVR bcoz its easy to use and free net support is available. i first tried PIC 16f628a made programmer but got stuck in assembly lang. while avr is easy to use avrstudio n winnavr makes easy to use n use c lang also
u need to give a pulse at one phase then after a delay give the pulse to second phase n so on in a cyclic way.the delay can b minimun depending on the motor.u can also give pulses to adjacent phases together to generate more torque, then remove phase 1 n apply to phase 2n3. u ll need high...
i wanna know is there ne µc which has an inbuilt ASK/FSK RF transeceiver. and by inbuilt i mean to say that like we use USART as a peripheral ang directly write to its registers in a µc like in ATMEGA µc is there any µc which has an inbuilt RF transceiver whiich has its registers and v can...
Re: How to configure ATmega16 to run with external crystal o
external clock can be set by setting CKSEL3...0 bits.these bits ve to b manually set using programmer and is done in different ways using the programming software u use.but be carefull not to mess with others bits if u dnt know there...
im using two mosfets in parallel each rated 55A my motor cant take more than 96 A starting since its 48V 0.5Ω so I is 96 max,dnt know wats the prob. can it be related transients.
i made a control circuit based on µc for PWM speed control of a 48V 0.5 Ω PMDC motor using mosfets.it worked fine but the next day when i again tried it mosfets blew. im still not aable to find out any reason plz help what can b the prob.earlier when it was working mosfets didnt heat at all but...
use atmega8 or 16 both r really good and you can program them in ISP mode using only 5 wires connected to parallel port,you can find many helpful tutorials on net
48V24A dc motor control
im trying to control a 48V 24A c motor(pemanent magnet) using mosfets ,can any one guide me ,ill b giving PWM using µc ,i want which mosfets to use drivers and any problems that can arise thx in advance
dc motor control
i want to control a dc motor 48V 24A using a power mosfet can any one help me out with which mosfet to use, circuit diagram . im planning to generate PWM using ATMEGA16
you can use a dtmf to bcd decoder.you ll get a bcd output which you can interface with a µc and do whatever you want.once i used this to interface with a mobile phone to control 4 switches of course you can control more .heres a schematic which you can connect to landline and control 4...
i controlled a stepper motor using l293d ic and atmega16 its working fine but is quite slow if i try to increase its speed it gets saturated and stalls i heard sumthing like current chopper drive for stepper motor but dont know what is it exactly,sumone used it n is getting better performance...
need some help with atmega16 comparator.can anyone give me some C code for using comparator.any example will do.interupts will b added help thx in advance
i startedof wth atmega16 avr i think its qiutre simple.just download avrstudio4,winavr from gcc and u r ready 2 go.u can burn it wth a number of circuits on net.there r many tutorials to get u started.njoy..
