Hello i have a problem with the PR46-15 Module.
Using both an Arduino Nano and a Raspberry Pi Pico i can detect the Module at 0x60 but can’t get it to output a voltage.
On Capacitor CE1 i measured around 10V so i know that the module is capable of producing the Output.
Using the same Code for my PR33-26 gives me the desired Output. Therefore i believe that the Module has a problem.
If anyone can help me figuring out if my assumption is right or not. I would greatly appreciate it.
I took a Photo of the Module for reverence.
My test code from the Raspberry Pi Pico for reverence:
import machine
#-------------------------------------------------------------------------------------------
Initialisierung I2C
i2c = machine.I2C(1, sda=machine.Pin(14), scl=machine.Pin(15), freq=400000)
def scan():
# I2C-Bus-Scan
print(‘Scan I2C Bus…’)
devices = i2c.scan()
# Scanergebnis ausgeben
if len(devices) == 0:
print('Kein I2C-Gerät gefunden!')
else:
print('I2C-Geräte gefunden:', len(devices))
for device in devices:
print("Decimal address: ",device, '| Hexadezimale Adresse:', hex(device))
def current_control(ADDR, DAC_Value):
data1 = DAC_Value >> 4 # MSB are used
data2 = DAC_Value & 15 # LSB are used
data2 = data2 << 4 # LSB in Byte
data = bytes([data1, data2])
print(data)
try:
i2c.writeto_mem(ADDR, 0x41, data)
print("Writing Value to DAC %d " %DAC_Value)
except: print(‘Cant reach I2C Device’)
