Hi guys. I've searched the forum but couldn't find the answer to my questions.
So I've started following this guide (https://pit.uriba.org/uriba/standalone-cougar-tqs-part-i/) to get my old TM Cougar from DB15 to USB using an Arduino Leonard instead of an Pro-Micro.
I've followed the wiring as shown in the guide, except I have used pin A4 instead of the external ADC.
The problem is the uploading of the firmware to the arduino. The README files states the following (located here https://github.com/uriba107/32u4_hexuploader/releases/tag/v1912):
Allow to upload code both to Serial enabled boards (that have an exposed COM port), or devices in other modes (not Com port visible.
to upload to visible device, select it's COM port from the drop down list. and click upload. for a Non visible device, select the proper option and click upload. then reset the device to Bootloader mode (usually "double click" on the devices Reset button.
the program will identify device's bootloader and will upload the selected HEX file.
When I open the Hexloader program, the arduino COM port is not shown and when I set the arduino in bootloader mode (connecting RESET and GND twice) and uploades using the HID alternative, is states: No device found.
I can see the Arduino listed in the device manager. Also tried to run the "upload_code.bat" file but it failed since there wasn't any hex file with the correct name.
