Serial port (com) What name is specified in dev? what is tq2440_serial0?
Serial port (com)
In linux, if you use mini2440 serial ports, they are named ttySAC0, ttySAC1 and ttySAC2, you can see them if you access /dev/ folder.
Ok I see /dev/ttySAC0 and try to canect it by python but see this Error 00000 then try by Converter com to usb and use /dev/ttyUSB0 my cod work very good ! Kernel could be a problem?
Hi lamp the factory default kernel dosn't support usb to serial devices. You must compile your own kernel, this feature enabled. make menuconfig Device Drivers --> [*] usb support --> [*] USB Serial converter support --> <device> Which <device> to check, this I tried out on my host system. Plugging in the device, after them a dmesg call shows you the used driver.
tanks i am try whit Serial Port Assestant and select /dev/ttySAC0 and clik on connect but show this messege : setting error cannot set parameters can help me to set this parameters.
