HiCan anyone help me!!!
Is it possible to change operating mode of WTV020SD-16p module? I read the datasheet several time but there is nothing mentioned about mode selection. And also i can't get the current mode.
Actually for this module i don't use arduino module so I want to make code for AVR microcontroller manually (without using Arduino functions).
I don't know that module.
But just checking, you do know that Arduino code works on stand-alone AVR chips? The board has the USB interface and some bits but that is all, it is for development even though it often gets used in hobby level end products.
Here are projects that use V-USB to access USB directly from even small AVR's:
