*Subject:* doing rs232 serial with binary data ?? with pyserial??
Hello group;
I am new to python and worked mostly in C & C++ (and assembly). I do
embedded controls and usually use the internet or LAN to log data and do
controls.
So, in Python I found pyserial and wish to use it to send binary to
controlled devices (in this case to a Modbus protocol solar charge
controller (TriStar TS-60).
In C++ I would setup ‘structs’ or class attributes to hold the byte
oriented commands and controller responses and then send them to rs232
as binary. I do not see how to do that with pyserial.
What I need is to send and receive binary (not strings) over rs232. In
this case from/to a Raspberry Pi (RPI) controller to/from the solar
charge controller. The RPI runs apache server to handle the network.
Any suggestions will be greatly appreciated. I have been using
Python2.7 so far.
Thanks
Doug
