I'm writing a program to send data over the serial port. I'm using pyserial, and I'm on WindowsXP. When I use literals I can get the data accross how I want it for example:
1 2 3 4 5 6 serialport.write('!SC'+'\x01'+'\x05'+'\xFA'+'\x00'+'\r') 1=Get devices attention 2=Select channel on device 3=Rate for movement 4=Low byte of 16 bits 5=High bytes of 16 bits 6=Carriage return signaling command is over This command works as desired. Sends the first 3 ASCII characters, then some numbers in hex followed by a carriage return. My problem is that the "write()" function only takes a string, and I want to substitute variables for the hex literals. I know that I can use the "hex()" function and it will return a string with the appropriate hex value, and I could combine this with some other literals like "\\" to create my desired hex literal, but then I would need something to re-parse my string to change my ASCII text into the appropriate hex values. Any ideas on how I may do this? Any help is greatly appreciated. Thanks, Will -- http://mail.python.org/mailman/listinfo/python-list
