Here are the sch of all of the circuit, please tell me, DC-DC and DC-AC stages working fine independently but when we input from DC-DC stage to DC-AC stage, the microcontroller stops working,
please remember we are using IRG4pc50ud IGBTs
we are going to make a 2 stages sine wave inverter using IGBT H-Bridge on DC-AC stage, when we apply 12V DC power source on H-bridge the circuit works okey, but when we provides high voltage DC from DC-DC stage, which is about about 350volts at input the microntroller(PIC18f26k22) does't...
Hi, I want to make a multi channel MP3 player,
This means i need to play at-least 4 different files from single source(SD card etc) in real time, please advise me weather i use micro-controller+vs1011e variant chips or implement a software in raspberry pi, FPGA PIC32 etc
Its complete cable assembly
When i use this cable as a null modem eg connecting directly pin 2 to pin 3 it send and receive same character but
I also tried TUSB3410 complete cable assembly but its also not working as null modem i did not test with micro-controller, I test this cable to send...
I am using USB to RS232 (CH340) cable to communicate with micro-controller
I tried both 89s51 and PIC 16f628A both controller working well when using in Proteus simulation but when i try i in hardware I receive unknow charactors ,
I am using asynchronous communication , can any body help how...
I am making a solid state relay using mox3040 zero cross detection and BTA12-600 Triac,
The purpose of this Project is to switch the power source on failure in minimum possible time,
For failure detection, I am using ADC of 18f452, by sampling whether the power is fail or not
In general we...
I am afraid to say that my propose not exactly to use audio tones, but is to make a digital wireless link by means of any thing that can we use instead of RF modules, in simpler way I want to do it using without RF modules, My poor knowledge says that audio tones is a way, because such a...
Yes i know its slow but I just realize that its very very slow,
Perhaps it will work or not, for sending and receiving commands and status to general equipment like switching and data longing sensors eg. fan speed, temp. relay
To make it fast, i just get a new idea, that is to eliminate the...
Due to high price of Wirless modules I am going to design a cheap solution that is
to convert rs232 signals to dtmf tones and send it over air and in reverse process retrieve it back, i have no idea how to send digital signals over air using easy to find components, I need help me on it...
how to set config bits in 16f887 as it have MCLR enable/disable capability and also internal osc,
I am getting problem to use internal osc, and also gives problem with original LCD.C problem, it gives busy statement while simulate on Proteus, so i change __delay_us(E_Delay) to __delay_us(10)...
Yeh is just got a new one, i think this is not a reasion.
The oscillator freq is 20Mhz.
The code i use in MikroC is for 80s52
void main ()
unsigned char j=1;
P0=j; // same as for pic, with TRISA=0; and...
I am trying to implement a simple blinking circuit on bread board to checking purpose
I try for both atmel 89s52 and PIC18F452 for testing
I program 89s52 on Mickro C and Keil,
and PIC18F452 on Micro C and CSS C as well
I use old computer power supply to power them,
I am using Genius G540 to...
i have got such a errors after all, as i am using latest version of mikroC 5.61, also i did not simulate it on Proteus as it works or not,

actually i am going to make pickit2's PCB, i try several times to printout, but their is always a problem with scaling, that, pcb print is always little bit smaller then the orignal one, that i can not place a IC in it, as their is many schematic diagrams are available i try 2 of them, but the...
