I'm using some of the sample Python code to understand how to read data from MCC 134 and 152 HATs and when I run the hat_list function I get back that Board0, Board1, and Board2 are connected when I only have two HATs connected. After that I'm trying to read data from both boards and I get the following result.
Here is the Python code I'm using. Any helped would be appreciated.
//!/usr/bin/env python
import sys
from daqhats import hat_list, HatIDs, mcc134,mcc152
get hat list of MCC daqhat boards
board_list = hat_list(filter_by_id = HatIDs.ANY)
for entry in board_list:
print("Board{}: ".format(entry.address))
if not board_list:
print("No boards found")
sys.exit()
Read and display every channel
for entry in board_list:
if entry.id == HatIDs.MCC_134:
print("Board {}: MCC 134".format(entry.id))
board = mcc134(entry.address)
for channel in range(board.info().NUM_AI_CHANNELS):
board.tc_type_write(channel,1)
value = board.t_in_read(channel)
print("Ch {0}: {1:.3f}".format(channel, value))
elif entry.id == HatIDs.MCC_152:
print("Board {}: MCC 152".format(entry.id))
board = mcc152(entry.address)
for channel in range(board.info().NUM_AI_CHANNELS):
value = board.a_in_read(channel)
print("Ch {0}: {1:.3f}".format(channel, value))
