SPI FRAM Reading And Writing

This example is a very brief demonstration of using SPI to read from and write to a SPI FRAM device. This particular examples uses the 64Kbit FRAM Breakout Board from Adafruit.

from binhoHostAdapter import binhoHostAdapter
from binhoHostAdapter import binhoUtilities
# Change this to match your COMPort
default_commport = "COM11"
print("SPI FRAM Example using Binho Host Adapter")
print("v1.0 -- Jonathan Georgino <jonathan@binho.io>")
print
utilities = binhoUtilities.binhoUtilities()
devices = utilities.listAvailableDevices()
if len(devices) == 1:
COMPORT = devices[0]
print("Found 1 attached adapter @ " + devices[0])
print
else:
COMPORT = default_commport
print("Found more than 1 attached adapter, using default port " + COMPORT)
print
print("Opening " + COMPORT + "...")
print
# create the binhoHostAdapter object
hostAdapter = binhoHostAdapter.binhoHostAdapter(COMPORT)
print(hostAdapter.setOperationMode(0, 'SPI'))
print(hostAdapter.setClockSPI(0, 1000000))
print(hostAdapter.setModeSPI(0, 0))
print(hostAdapter.setIOpinMode(0, 'DOUT'))
print(hostAdapter.setIOpinValue(0, 'HIGH'))
print(hostAdapter.beginSPI(0))
print(hostAdapter.setIOpinValue(0, 'LOW'))
print(hostAdapter.transferSPI(0, 0x9f))
print(hostAdapter.transferSPI(0, 0))
print(hostAdapter.transferSPI(0, 0))
print(hostAdapter.transferSPI(0, 0))
print(hostAdapter.transferSPI(0, 0))
print(hostAdapter.setIOpinValue(0, 'HIGH'))
print(hostAdapter.endSPI(0))
print(hostAdapter.clearBuffer(0))
print(hostAdapter.addByteToBuffer(0, 0x9f))
print(hostAdapter.beginSPI(0))
print(hostAdapter.setIOpinValue(0, 'LOW'))
print(hostAdapter.transferBufferSPI(0, 5))
print(hostAdapter.setIOpinValue(0, 'HIGH'))
print(hostAdapter.endSPI(0))
print(hostAdapter.readBuffer(0, 5))
