I am are looking for an experienced developer to modify the open source program "Friture" specifically for the Raspberry Pi 4. The open source project can be found at www.friture.org.

The ideal candidate should have experience with digital signal processing, Raspberry Pi and Raspian. The modifications to be made require an understanding of the Raspberry Pi, Raspbian, and programming skills.

The Program Friture should be modified so that a universally portable FFT analyzer can be implemented using this app in conjunction with the Raspberry Pi 4.

The following modifications are necessary:
1. get Friture running on the Raspberry Pi 4 under Reaspbian.
2. to extend the frequency spectrum of Friture to 100kHz.
3. to extend only one channel (and not 2)
4. the signal to be processed is processed by an external ADC.

The external ADC is not predefined and any ADC can be used which allows this task. However, the connection at the SPI has (according to my research) some pitfalls for this bandwidth.

Hints for this can be found here:

https://raspberrypi.stackexchange.com/questions/81819/how-to-achieve-a-high-sampling-speed-using-an-adc-with-raspberry-pi


I´m  looking for someone who is highly skilled and experienced in this field and who can provide us with high quality modifications to the Friture program.
