My code is horribly wrong. Thank you for pointing it out !
Making the circuit proper/tidy will solve this I hope.
It is the pic of PCF8591 sending bytes of '255'. The addressing sequence only lasted for a short period of time, so I could not capture it properly.
I did what you said, still the...
How does the microcontroller drive it to HIGH IMPEDANCE? How do I incorporate it in the code?
I am attaching the scope pic and circuit pic below. Sorry for he bad quality of the circuit pic.
I am trying to interface multiple PCF8591 (around 5) to a single Raspberry Pi using I2C protocol. Since a Rpi has only one set of SDA and SCL pins, I am trying to bit-bang to make the other GPIO pins work as SDA and SCL. I am trying to use RPi.GPIO library for making the bit banging code in...
I wanted to build a circuit which would produce a set of signals of different frequencies in different channels simultaneously using a single reference source. I also want the frequencies to be changeable. I am looking to generate frequencies in kHz and MHz range. On searching on the web I came...
I am trying to detect different frequency signals using a Raspberry Pi and an ADC converter (PCF8591). My initial guess was the highest frequency I could detect would be limited by the speed of the I2C bus (which is about 400000 bauds). But when I run the setup, I could only get sampling speeds...
I am using a Raspberry Pi 3 Model B to read the signal generated by a function generator. I have used PCF8591 fitted in YL-40 PCB as the ADC. I have used python for establishing the I2C communication between the Rpi and PCF8591. But, I am getting undesirable values when I run the setup.
The...
I am trying to work with the signals generated by a function generator using Raspberry Pi. Since Raspberry Pi does not have an inbuilt ADC, I used pcf8591. Now, I do not know how to feed the signal generated by the function generator into the input pins of pcf8591. Please help.
I wanted to interface Rpi with the function generator Keithley 3390. My goal is to capture the signal which Keithley 3390 generates and plot it using Rpi, i.e, to function it as an oscilloscope. I went through the reference manual of Keithley 3390 but could not come up with a solution. Please help.
I am trying to understand how ADA2200 works using the datasheet. I am getting confused because the components specified in it works for digital electronics but it is also said that no ADC is being used and something called Analog Sampling Technology is utilized. It will be very helpful if anyone...
I am trying to simulate ADA2200 in Multisim. The device is not readily available in Multisim library. So, I downloaded the SPICE netlist code for it from Analog Devices. I tried to make a component in Multisim using this code. But I am encountering an error (It was also commented in the code...
Hi,
I am trying to make a lock-in amplifier which can detect signals having frequencies near 1GHz. I did not find any circuits which can accomplish this feat. Can anyone help me how to start solving this problem?
As of now, I have been using AD630. It stops working around 32KHz. My focus is to...
