Apologies if this is the wrong place to post, If so it would be good to know where I can get some advice. I have searched a lot for a solution to my problem and haven’t found much. I will describe my issue as simply as possible.
I own a minicommand which is an atmega 64 based midi controller and processor. Having not used it for a while I connected the incorrect psu AC9v by mistake . When I switch it on now it doesn’t load to either program or bootloader as before but instead lights both led’s and shows a full lcd display. If I hold buttons and turn on (previously this accessed different modes) It does the same but without the backlight. I have tried to connect to the device through both pieces of software I have on my laptop (a patch loader and a sketch compiler/loader), neither can make a connection through the midi ports.
I have some questions and would be very grateful if someone could help:
Is it possible to connect via usb to serial (midi ports) and diagnose or reprogram this device?
Has the boot loader simply been erased or is it something possibly more serious/totally different?
Thanks, does anyone have any ideas?
