PlainDAQ is a module that turns your Raspberry Pi Pico into a simple, precision 4-channel oscilloscope and a single channel function generator. Optionally it can also include a Wi-Fi module to add wireless capability to Raspberry Pi Pico modules.

To put it other words, PlainDAQ is a simple, useful tool to add basic precision analog functionality to your Raspberry Pi Pico board. It has a precision, low-noise, low-drift 12-bit 500kSPS/s ADC, sampling 4-channels and supporting 3 ranges (±1V, ±2V, ±4V). It also has a 10-bit DAC which helps create analog outputs and waveforms and it has a single range of ±4V.

It's going to have its own GUI to visualize the waveforms captured via oscilloscope inputs and to control the waveforms generated.

This job required me to prototype an isolated USB3.0 to FPGA interface.
This application called for very high-speed data transfer (up to 600MBit/s) for a very large measurement system.
I needed to design a simple and easy to use interface with FPGAs and it had to be isolated. Isolating USB3.0 was not a trivial task. Managing FPGAs timing constraints was also not a walk in the park.

I needed to find a way to isolate USB3.0 which is the most difficult part of the project. There isn't any available off-the-shelf solution that is able to isolate USB3.0 line (they are bidirectional which adds to the difficulty), and therefore I decided to use multiples of generic 150Mbit/s 6 channel isolators to isolate the parallel data coming from the equipment part (as opposed to USB part).
FT601 chip is used.

After the design is complete I assembled the board, wrote some VHDL, fixed timing issues and tested with python and I achieved a whopping 190MByte/s bulk transfer speed.

This job required me to design a very accurate and low temperature drift voltage reference generator and distributor sub-system.
The voltage reference is used to supply reference voltage precision ADCs and they are also utilized to calibrate the system by applying the voltage to the input of the instruments.
Customer needed various voltages to be applied at the start-up of the unit to calibrate out the offset and gain error of the equipment.

MAX6126 is selected as a reference because of its low-noise and very low temperature drift to generate 4.096V.
The reference system had 25ppm/°C temperature coeffiecient. This is suprisingly dominated by the resistor arrays, but the drift was adequate for the application.

Very accurate differential signal generator is needed to calibrate a device that has differential input.

Here are some of the requirements:
-Adjustable common voltage
-Differential signal up to 5 MHz
-Output must be harmonically pure(below 90dB at 1 MHz)
-The unit must be controllable via USB (isolated)

The most difficult part was to generate 1 MHz differential signal with below 90dB harmonic distortio
