How to upload firmware to the MK312-BT using an arduino

Here are the CMD commands I use in the video so you can copy & paste them. Don’t forget to check the com port and firmware file name!

Test Connection
avrdude -c avrisp -P \\.\com24 -b 19200 -p m16 -t
Set Fuses
avrdude -v -c avrisp -P \\.\com24 -b 19200 -p m16 -U lfuse:w:0xff:m -U hfuse:w:0xDC:m
Upload Firmware
avrdude -v -c avrisp -P \\.\com24 -b 19200 -p m16 -U "flash:w:312-16-Dev_BL.bin"

Channel Chopper Schematics, PCB’s and Arduino Code

Have finally got around to uploading all the information on the Channel Chopper. It’s currently a Patreon exclusive and can be found here

I will be releasing it to everyone at some point so don’t worry if you don’t want to support us
