swc_usb's Issues
SWC usb fully assembled
Hi, sorry for this issue opened, i need a fully assembled swc usb, do you have for sale?
Can't install the hex or any drivers.
Hi there, please try to excuse the lack of knowledge, I don't use python and never used one of these boards
No drivers came with the board
https://www.ebay.co.uk/itm/352722795632
I plug the board on to Windows 7 and I presume I press the button to stop the flashing but but using the suggested line for avrdude from your posts on here yields a cannot find \dev\usbmodem411 error.
Any help would be appreciated, the soldering I can do...
Hi Tore
Not ann issue but a bit of help needed re the Wildcard. I'm going to do the initial way you made it with no custom PCB but I presume you have to flash the ATMEGA32U4 with that hex, I've never done this before, can you give me a bit of help. Soldering is all fine, just the flashing and possible any other software I'm going to need?
Sorry to trouble you..
Can't flash hex file.
Hi,
first of all, really nice project! I'm looking forward to upgrade my swc!
I've bought this ATmega32u4 (http://www.ebay.de/itm/301951688967?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT)
Now i'm trying to flash your hex file via avrdude on osx 10.11.6
first im not sure do i need to write into the flashmemory or the eeprom?
anyway i tried to verify both with the following two commands, both fail while verification:
Flashmemory:
avrdude -p m32u4 -P /dev/cu.usbmodem1421 -c avr109 -U flash:v:$(pwd)/Desktop/swc_usb.hex
