Re: UART from laptop to pi

... the 5V Vcc is being used. I've been using these things for many years on Raspberry Pi computers and other devices and prefer them over PL2303 or FTDI based adapters.

Re: ftdi driver under mono

As far as I can tell the driver in question is for a com port chip. Why does your application need to know anything about a specific serial port hardware device? On Linux systems the kernel has all the drivers for various serial port devices. On the Pi SoC itself, USB/serial adapters etc. Applicatio...

Re: create 2 serial ports?

I came to say that I know you can use pigpio to bitbang with any gpio, but if I have to write as well as receive (at the PI) I usually just use an FTDI because it's a little bit of a dance to create waves.

Re: Raspberry Pi 3B FTDI FT232R USB UART adapter

I did not need a serial adapater to program the esp8266 in a smart switch (Sonoff) - just used the pi serial TX/RX GPIO pins. Same for esp8266 board ESP-01 maybe off-topic question to above....but its just one-off: are you programming your esp8266 using ArduinoIDE? (a Yes or No will suffice) ;)

I've tried to upgrade multiple times over a period of multiple months, with different SD cards. This is why I suggested you try with a new SD Card and a fresh Raspbian install. If it works with that, but not with what you have, it suggests something has gone askew in those upgrades. Are you using B...

I did, I'm still getting the same behavior. modprobe ftdi_sio also gives the same error.

The difference between the OP's and hippy's dmesg output is that the OP isn't getting the ftdi_sio kernel module loaded. So as a temporary measure, before you plug the device in, try: sudo modprobe ftdi_sio then plug it in. Thanks for your response. I believe we may be getting closer to the actual ...
