Need help measuring photodiode current

Greetings! I need help.
Short description
Architecture: transimpedance amplifier (TIA). Physically consists of two separate boards. “Amplifier + ADC” and “Interface”.
Purpose: photodiode current measurement. Replacement for Model 3300
Measuring range: from units of picoamps to 10 milliamps
Power supply: from 5 volts USB or external source. Switching by jumper/jumper.
Number of gain ranges (multiplier/feedback): 4 pieces
Amplifier Output Offset Correction: Small offsets can be corrected directly in the ADS1262 ADC. Large can not lose the dynamic range.
Bandwidth: somewhere in the range of 0.5-5 Hz.
Analog output: yes

Interface board : based on esp32 microcontroller with USB2.0 interface and Ethernet
Amplifier board control via SPI (1) directly to ADS1262 ADC
And relay SPI(2) (AGN21003 - RELAY SLIM LATCH DPDT 3VDC PCB) 7 pcs via shift register 74HC595PW

so, what problem do you meet?

Do you want to showcase something or seeking for help as your question dose not satisfy any thing

What is a model 3300? Do you have the means to do a calibration of your system for those currents?

i need help to make script

What have you tried and what are the results?

Ask the supplier for the ESP32 code.
