# CAEN - Nuclear Instruments A7585A/NIPM12 Python Control Library
The NIPM-12 SiPM Power Module is a compact and integrated solution to provide stable and noiseless power supply for single and array / matrix SiPM detectors.
High resolution Output Voltage and Output Current measurements enable the NIPM-12 to be used for I-V detector characterization.
Digital (UART, I2C and USB with adapter) and analog control interface are runtime selectable by a single pin or a digital command.
The module integrates a temperature HV loop that regulates the SiPM output voltage as a programmable function of the SiPM temperature coefficient.
This library is a python A7585A/NIPM12 module. It allows to control the module using the UART/USB interface.
## Features
- 20-85V Output Voltage
- 10mA Output Current
- 1mV Output Voltage step
- Less than 300uV rms noise
- User Selectable Digital / Analog output voltage control
- Automatic temperature feedback on the output voltage
- Multi device support using I2C
- Fully working examples designed to control the module with keypad and display or monitor multiple devices using serial port
- Module compatible with ZEUS software for stand alone usage
## Pinout of the module
## Python installation
In order to install the A7585D python Library, just run the following command:
```bash
pip install a7585d
```
## Usage
### Module user manual
The user manual can be downloaded from the CAEN website:
[https://www.caen.it/products/a7585/](https://www.caen.it/products/a7585/)
### Import the library
Import the library in your python script:
```python
from a7585d.a7585d import A7585D
from a7585d.a7585d import A7585D_REG
```
### Create the A7585D object
Create the A7585D object and connect to the module serial port:
```python
hv = A7585D()
# open serial port
hv.open("COM3") # Windows
# hv.open("/dev/ttyUSB0") # Linux USB
# hv.open("/dev/ttyS0") # Linux UART
```
### Full code example
Create the A7585D object and connect to the module serial port:
```python
from a7585d import A7585D
from a7585d import A7585D_REG
import time
hv = A7585D()
# open serial port
hv.open("COM3") # Windows
# hv.open("/dev/ttyUSB0") # Linux USB
# hv.open("/dev/ttyS0") # Linux UART
# configure parameters HV
# set control output control loop mode
# 0 Digital mode (output voltage is vtarget)
# 1 Analog mode (output voltage is proportional to vref)
# 2 Thermal compensation (output voltage is vtarget - Tcoef * (T - 25)
hv.set_parameter(A7585D_REG.CNTRL_MODE, 0)
# set voltage target to 40V
hv.set_parameter(A7585D_REG.V_TARGET, 40)
# set max voltage 1mA
hv.set_parameter(A7585D_REG.MAX_I, 1)
# set max voltage (compliance) to 50V
hv.set_parameter(A7585D_REG.MAX_V, 50)
# configure SiPM temperature compensation coefficient
hv.set_parameter(A7585D_REG.T_COEF_SIPM, -35)
# configure ramp speed to 5V/s
hv.set_parameter(A7585D_REG.RAMP, 5)
# set current monitor range
# 0 low range
# 1 high range
# 2 auto select
hv.set_parameter(A7585D_REG.CURRENT_RANGE, 2)
# control pi controller (1 enable)
hv.set_parameter(A7585D_REG.ENABLE_PI, 0)
# enable hv
hv.set_parameter(A7585D_REG.HV_ENABLE,1)
while True:
print("HV V_OUT: " + str(hv.get_parameter(A7585D_REG.MON_VOUT)))
print("HV I_OUT: " + str(hv.get_parameter(A7585D_REG.MON_IOUT)))
time.sleep(0.1)
```
