I have a real time signal, a new sample is coming continuously and needs to be filtered before further processing. I want to design the filter in C. But I don't have much experience in C.
Could someone give an simple example of C-code so that I can go further. e.g., I need to filter the real...
I want to learn microprocessor programming, not only as a hobby but as something that will be useful professionally.
I already have worked on Arduino for a while, and also have little basic knowledge on 8051 assembly programming.
To learn microprocessor programming, which is the better? I have...
I am using LT3525 as 5V dc-dc converter to power my microcontroller. And, I am using the in-built ADC. But, I get some ripples on my ADC readings, which I guess is due to the ripple of dc-dc converter because I do not get those ripples if I do not use the dc-dc converter. So, how can I get rid...
Sorry for the link. I corrected it. Now, its working. Its CR43NP-4R7, 4.7uH inductor. This is the one of the recommended inductors in the datasheet of the LTC3429, for this application. I am just confused about the pins, because it has 4 pins, and I need only two pins.
I want to make dc dc converter. So I bought **broken link removed** as recommended in datasheet. But this inductor has 4 pins while I just need 2 pins; one to Vin and one to SW.
how/which pins, do I connect the pins to Vin and SW?
I need to generate 0.5 mV to feed to IN-amp. But the minimum voltage my signal generator can generate is 10mV peak-to-peak.
I tried using this voltage divider to get 0.5mV at +ve input, but doesn't work. The output is like 20 times smaller.
How can I get this small voltage?
Today, I found out that this is due to the function generator/oscilloscope. For some reason, if I connect one channel of the oscilloscope at the IN-amp input where function generator is connected, it shows correct output. If I do not connect oscilloscope at input, it shows double the expected...
I need 3.3V to run a wifi module RN131.
It has maximum supply of 3.7V. But the simulation of my DC-DC converter design shows that the voltage goes up to 3.9V and then comes down to 3.3V. Can this 3.9V damage the module?
Hi. Thanx to everyone for your effort. But the problem is not solved yet.
Actually, I had already designed the PCB for that circuit after simulation. Its a part of ECG amplifier. The eagle schematics of this part is attached here. Since it was giving me double of expected gain, I checked in the...
I am trying to test the attached ciruit. I am using INA128 which has the gain of 1 + 49.4k/Rg. When is use two 2.7 kohm resistors, I was expecting gain of 10 but I am getting 20. I tried with AD620, using different resistors too and in different frequencies (0 - 200 Hz). And, the output is...
