Typical framework consist of FPGA bit file, with runs on Red Pitaya programmable logic, a server app which runs on Red Pitaya processing system (CPU), and a client app with runs on a host

Bitfile creation example: https://pavel-demin.github.io/red-pitaya-notes/led-blinker/

A simple RP 122-16 ADC recorder example located in ..\projects\adc_recorder_test_122

On the development machine: Command to create the bitfile: make NAME=adc_recorder_test_122 PART=xc7z020clg400-1 bit Command to compile the ADC recorder clien app: arm-linux-gnueabihf-gcc -O3 -march=armv7-a -mtune=cortex-a9 -mfpu=neon -mfloat-abi=hard -o adc-recorder-test adc-recorder-test.c

On Red Pitaya: Command to program FPPA with bitfile: cat adc_recorder_test_122.bit > /dev/xdevcfg Command to record ADC waveform into a file: adc-recorder-test > data.txt

cd /opt/tmp cat /opt/adc_recorder_test_122.bit > /dev/xdevcfg /opt/tmp/adc-recorder-test > data.txt
