I can not get the new Arduino 2.0 or any 2.0-rcx to select a serial port, I have used it successfully many times with all 1.8,19 down though 1.8.11.
In 2.0, I can select the board, in my case attiny85, clock 1khz etc. But can not upload programs I have successfully used in the 1.8.19 IDE.??? I am using a new DELL XPS with Windows 11. I used ZAGID to install drivers. Device Manager shows FabISP under Libusb-win32. I can see it appear and disappear as I plug and unplug the programmer. I have copied the ATTINY add on, listed for IDE 1.6 and up, to the PREFRENCES. I believe that is working as it shows in the Board Manager and is selectable.
My concern is that the driver from ZADIG shows as libsub-win32. Is their a win64 driver needed?? If so where may I find it? BUT I can program with this setup using 1.8.19?
I keep 1.8.19 on the computer to program a teensy 4.1 and the attiny85 using the programmer. We can now use 2.0-rc6 to program the teensy4.1. So I would like to solve this port problem with the Tiny Programmer.
Thanks in advance for any and all suggestions and help!
Are you sure there is a serial port? My understanding is that the SparkFun "Tiny AVR Programmer" is a pure USB device that does not present a serial port.
From the "Arduino Quick Reference" document provided on that product page:
Serial Communication
A separate USB to serial adapter like FTDI is
needed for Serial communication with the ATtiny.
There is a bug in the Arduino IDE 2.x that prevents uploads when there is no serial port selected. The reason that is a bug is because some boards (including the Tiny AVR Programmer) don't use a serial port to upload:
The workaround for that bug when using the Tiny AVR Programmer is to use Sketch > Upload Using Programmer in the Arduino IDE to trigger the upload rather than the usual approach of clicking the "Upload" button (or using the Ctrl+U keyboard shortcut or Sketch > Upload menu item).
Please give the "Upload Using Programmer" technique a try and let me know if you have any problems with uploading that way.
You are welcome. I'm glad you are able to upload now.
I sometimes manage to circle back to the forum topics and post an update, but the truth is that I am not very reliable on that.
