I’m new to this whole arduino thing and I wanted to use the pro micro to make this http://gimx.fr/wiki/index.php?title=DIY_USB_adapter, When I tried uploading the correct firmware for GIMX on windows with Atmel FLIP, It said could not locate the USB device even when the drivers were installed. Then I tried it on my Mac with dfu-programmer and It said no device present. So after extensive reading I shorted the GND and RST pins to see if it would fix the problem but now the pro micro’s power led indicator (The red one) does not glow. However on my Mac it does but so faintly to the point where I didn’t even know it was on. At this point I gave up and decided to get a teensy instead but today the other component for the serial adapter (The CP2102) arrived in the mail and I decided to set it up.
The CP2102 serial converter has 5 pins and the serial adapter requires 3 of those to be used. GND on the pro micro goes to GND on the serial adapter however TX goes to RX and RX goes to TX. If I connect GND and RX/TX, The power goes to the pro micro without the usb micro b cable and the power indicator lights up as normal. Also the pro micro no longer shows up on device manager. I only have two usb micro B cables, One is both power and data (Which I am using) whereas the other is just power but I think the problems lies in the GND and RST short.
Any help would be greatly appreciated as I have no Idea What I am doing.
