Hi,
I need help regarding serial communication using MATLAB. I know to open a serial communication the code is
obj = serial('COM1')
which configures the com port1 for serial communication. But if I want to change the code such way that
obj = serial('COMX')
where X is the number entered on a...
Hi,
Thank you for your reply. Actually on the motor data sheet it says starting current of the motor is 41A so it means it needs 41A to start. Although somewhere on the data sheet it says operating current is 3A. So I'm a bit confused. Do I need to choose a h bridge that can handle 41A? MOSFET...
Dear all,
I am trying to make a 48V 42A DC motor controller using PIC16F877A microcontroller. I know how to generate PWM using PIC micro. I would like to know ask you guys, what kind of electronics do I have to use to make the hardware. As I know PIC alone is not able to handle such high...
Thank you everyone. I was actually doing a wrong calculation on the delay. I have figured it out and my hardware is performing at its best. Thanks everyone for help. If anyone else needs help regarding this issue please contact me.
Thanks for the reply..
i am sending u a code with proteus design file..plz check that..the problem with the simulation is it says "ADC conversion started befor wait time expired" but it should not say that as i have a 10ms delay using delay_ms function.. plus on the proteus simulation the motor...
Re: photo transistor pic16f
hi tahmid..
thankx for the reply... i have also have almost the same code using ccp1con resister.. and u used the pwm library from mikroC.. i also want to know on ur asm code why did u have a compare mode on ccp2 pin??
by the way im also from bangladesh currently...
Re: photo transistor pic16f
hi mr. tahmid..
i was reading through your code. but i am having a question. why u having a compare mode at ccp2? and do u have c file for this asm code? im not good at asm...
quick reply would be appriciated....
thank you
i know mate u r working for me... i tried this and ur code shows 12 all right but the displays turns on one after another like blinking. if i reduce the delay the displays dont show anything and if delay is increased the displays blink slowly..
another question is how im gonna show 13 after12...
hi alex...
thanks for ur help mate.. im using common anode displays at RD0 and RD1 pins. i connected everything as on the link but still no result. the displays are blinking one after another. can u plz show me the way of using timer.. my code is below..
thanks
char display_digit[9]=...
dear....
i tried it with the code. but the problem is still on multiplexing. though i can lit one display and show digits but i cant show two different digits on two displays. plz clarify the multiplexing bit either using loop or timer. i tried it using delay_ms function but then the displays...
thankx for reply..my code is below. it is checked on the hardware and is working fine. the 7 segment display increments once a second and shows 0-9. but i need 2 displays to show 00-99. plz give me any link or source code for c language, not assembly...
void main() {
TRISB = 0x00; // port B...
hi,,
i am having problem with multiplexing two common anode 7 segment displays. i am using pic16f877. i am trying to implement a decimal counter 0-99. i can use one 7 segment display to show 1-9 but i do not know how to use two using multiplexing.
i am using mikroC pro and c prohramming...
