Hi Gurus,
I got to know that in ARM Cortex M3/M4 architecture, processor uses the code and SRAM region for the program execution. But sometime it integrates the Code as well as SRAM regions. Can anyone guide me how and why is this integration possible?
I need one example for that. Can anyone...
Hi all,
I am an embedded beginner and I want to purchase a board for my own knowledge development. I want to work on a board which gives me an exposure to work on Linux,device driver, RTOS and embedded application development.
I want a suggestion for the board for above mentioned skill...
Hi all,
I am working on a script which is supposed to send a mail to outlook using shell scripting. In my company, outlook is used for sending and receiving mails.
Now, I am allocated a task to generate the build report and send it to the module owner for paying their attention. I am able to...
Hello,
I do not know how to calculate that's why I am here for the help. I have selected them randomly and from one of the circuit from google images.
That's all.
If you know how to calculate then you are welcome for suggestions. I have asked for the help.
Thanks.

Hello,
Please check the power management section in this attached circuit. What's wrong in this? When I switch ON the circuit, inrush resistor burns out.
I need 36V/500mA output.
The value of X-rated capacitor C11 is 6.6uF, the resistor in parallel with the capacitor, R14 is of 470k. R15 is...
HI,
Actually I am developing a driver for LED tubelight. But first I need a source that can supply sufficient voltage and Current. Voltage and current both should be same. As you have told before, LEDs works best on const current, that's true. So I am trying to develop the source with input...
Hi,
I am working on 230V/50Hz AC and main concern is size so I compulsory have to go with the transformerless power supply. I am creating the driver for LED tubelight that works on 36V/1A. So to supply the driver, I need supply in DC from AC. That'swhy I am worried a little otherwise I am...
Hello,
I am in search of a circuit that can give 36V/1A output without using transformer.
I want to know why chokes and inductor is used in transformerless power supply circuits? Is this for increasing current?
I want to drive a load of 1A max. I have used the capacitor connected directly to...
Can you please guide me? I am a beginner in this. So I need your assistance. Will you guide me how to finish this in 5-6 line code?

The problem I am facing is that, while pressing the switch, Output does not change. It remains ON with full intensity. I changed the...
Hello,
Here I have attached the schematic and Program that I have developed. When I have run this program on my hardware, it doesn't work.
First, I have tried on development board, where the switch gives high logic to controller pin, so it works. But in my hardware, switch closes, it gives...
Hello,
I have achieved the voltage by changing the R(ON) resistor. I have obtained 32V at output. But when I tried to connect LED Tubelight, it did not worked.
Here is the complete schematic of my circuit. Please help me to solve this issue.
Thanks.

Hello,
I am creating an LED driver using LM3402HV. When I connect the circuit as shown in attached datasheet, it shows unusual response.
When I connect the R(ON) resistor to pin 7 and then measure the voltage on PIN 8, it reduces to 7V from 40V. My VIN voltage is 40V. My requirement is...
Hello guys,
I am confused that here the capacitance of 2000pF is mentioned so do I need to connect the capacitor too? If yes, then in parallel or series? I have tried but I did not get the 150Vpp 40kHz signal at output. So what is the problem?
Hello,
I have attached a circuit here. Please check and let me know, how I can use IFT? I mean I have connected IFT as per the circuit.
While driving the Ultrasonic sensor through transistor by providing PWM pulses of 40kHz, I should get the voltage at output of IFT. I have checked its...
Ok. But I do not know how to do this. I know how to generate PWM wave on OCR0 pin. What would be the next? It will be continued in generate. But I need only 13 cycles to the Ultrasonic sensor.
SO what I need to do next?
For 40kHz, I need to do prescaling and TCCR0=6C and OCR0 will be 204.
So I...
