Hello,
I'm new to pyusb and to working with usb devices in general. I'm trying to
read voltage data from a Tenma 72-7732 multimeter, but I'm having some
problems. This is my code so far:
def main():
import usb.core
import usb.util
import usb.backend
#find device
dev = usb.core.find(idVendor=0x1a86, idProduct=0xe008)
# did you find it?
if dev is None:
raise ValueError('Device not found')
else:
print "Device found"
dev.set_configuration()
endpoint = dev[0][(0,0)][0]
data = dev.read(endpoint.bEndpointAddress, endpoint.wMaxPacketSize, 0,
100000)
print data
main()
This finds the device, but gives a timeout error when it tries to read
data. Do you have any idea what might have gone wrong? The multimeter has
very poor documentation, so I can't go there for advice.
Thanks,
Libby
