My investigation and replies in this forum indicated it is very difficult (even possible). I was trying to bypass the rpi kernel level protocol to be able to interpret the bits coming the usb connection (as I desired). I understand you are trying to talk to a certain product (mouse) using usb. I am not sure if we are trying to do the same thing. I think I am doing the exact same as you, were you trying to connect to a Victron product using the V.E.

Can somebody help me (maybe a link or code) how to start reading from this USB converter? I do not need to write (at least I think ). On my search for PyUSB resources I did not find how to read from such a source. Printing would already be sufficient I guess as I believe writing to a file will then not be so difficult. Now I'd like to read from the device myself (writing in Python) and store this data in a file. With Minicom I also got a dump of the data which is being send from the device. This works, because: device = (idVendor=0x0403, idProduct=0圆015) is TRUE and the device is recognized (a Future Technology Devices International, Ltd Bridge(I2C/SPI/UART/FIFO converter). With lsusb I already found the connected converter and used to parameters in PyUSB to try to retrieve data.

I have a serial -> USB converter attached to the RPi2.

The number of characters transmitted depends on the magnitude and sign of the value. The ASCII formatted value of this field. Where applicable, this will be the same as the label that is used on the LCD. An arbitrary length label that identifies the field. Each field is sent using the following format:Ī carriage return followed by a line feed (0x0D, 0x0A). The device transmits blocks of data at 1 second intervals. This is how the data is send: Message format The signal is transferred with following parameters:īaud rate: 19200, Data bits: 8, Parity: none, Stop bits: 1, Flow control: none In the end the RPi should be a stand alone logger which at startup starts logging. I'd like to read from a component which is sending a serial signal and use the RPi2 as a data logger.

I'm a beginner in Linux/ Python, so sorry for maybe asking something quite simple for some of you
