The following is a simple test program for Microchip PICkit 2. It
does seem to work.
#!/usr/bin/env python
import usb
def opendevice(idVendor, idProduct):
devices=[]
for b in usb.busses():
for d in b.devices:
if d.idVendor==idVendor and d.idProduct==idProduct:
devices.append(d)
if len(devices)==1:
device=devices[0]
return device
elif not devices:
raise "Device not found"
else:
raise "More than one device found"
if __name__=="__main__":
device=opendevice(0x04d8, 0x0033)
packet_len=64
dh=device.open()
dh.setConfiguration(1)
print "set Configuration 1"
dh.claimInterface(0)
print "claim Interface 0"
#dh.setAltInterface(0)
# To get firmware version number
print "Sending version command by USB interrupt write"
dh.interruptWrite(0x01,"v"+(packet_len-1)*"Z",1000)
print "Getting version command by USB interrupt write"
r=dh.interruptRead(0x81,3,1000)
print r
