... volts or 5? You can check with a meter..if it's 5, you'll need a logic level converter of some sort so you don't kill the PIs 3.3 volt pins. An FTDI (USB-TTL serial adapter) is pretty darn handy to have anyway. I haven't tried it, but you you may be able to connect the RX wire on the pi (or ...

... drops to 30k. In theory, my experiments should be reproducible. (See the above URL for the code. You do need to connect to the UART, I'm using a ftdi chip from sparkfun.) I'm not too experienced in writing assembly (yet). Maybe I'm doing a something very naive, or what I'm doing is simply not ...

... All, I'm planning to integrate FT601 on my board to receive 32-bit FIFO (externally) and send these data to the Rpi via USB 3.0. According to the FTDI website https://www.ftdichip.com/Drivers/D3XX.htm , D3XX driver, which is required by FT601, currently does not support ARM microprocessor on Linux. ...

... know if that limit has been raised. - Linux still enumerates USB devices (almost) totally random at boot. if you for example connected 5 identical FTDI devices you would probably have to program them with specific ID/labels and then write some udev rules to link them to fixed device names. And ...

Setting the uploader to "ATMega328 16 MHz (Old bootloader)" when I read that it did seem familiar but I can't find it in the Arduino IDE I have version 1.8.10 installed Unfortunately I don't seem able to get a screenshot from my Pi with the menus open but ... For 1.8.10, clicking Tools, the drop-do...

If you're not seeing this on your Arduino IDE then your IDE version is wrong..

I just checked the Arduino IDE 1.8.10 on my RPi4B-4G desktop.... the "Burn Bootloader" menu item is there.

You have the wrong program downloader selected, some mismatch with what the Arduino has, so it's never seeing what it expects to see. Is there even a bootloader in the Arduino ? Oh yes, they do. It's a very small programme that allows the system to be updated from serial. As supplied, ICSP is about...

Fair enough. It's fairly unlikely to have no bootloader at all, but having the old bootloader has much the same effect. Many of the super cheap Arduino Nano clones still use the old bootloader. I picked up four or five that a local hobbyist was throwing out and the only problem was that they had the...

Is there even a bootloader in the Arduino ? Oh yes, they do. It's a very small programme that allows the system to be updated from serial. As supplied, ICSP is about the only way to do it.

Some Pi/IDE/FTDI setting is preventing things from working, such as wait for CTS to be signalled when it never will. You have the wrong program downloader selected, ...

You should be able to disconnect the FTDI from the Arduino, loop-back TX to RX, then run a test to see if it is sending and receiving data. You could use 'minicom' or something else. I have a Python program to check serial loop-back. You might ...

At the prices I'm seeing for those online, it's very unlikely to have an FTDI chip in it. It might not even be a serial device.

This is the general spec .. on Windows it works perfectly, but not on the PI

How is the Raspberry Pi powered?
What else is attached to USB?

Hi There, I've encounter this USB-Serial problem on Pi4 with FTDI FT230X chip: I have a device test farm that need to connect a lot of device for testing. I just purchased two Pi4 and hook up 24 (12 on each) FT230 usb-serial chip based device to Pi4 via ...
