USB programming

Question

I want to program a microcontroller (AVR) to control some leds through USB. It\'s just out of interest in how to build and program USB devices. There are some AVR microcontrolle

Answer 1

I had built my own test bed based on the ARDUINO UNO and i was using the ionlabs programmer of type usbasp and it worked perfectly fine but it did not allow to convert the TTL back to Rs-232 and hence i couldn't use the features such as serial.print() and i had to install the ftdi cable which allowed me to do this. The drivers were the libusb 1.xx working just fine.

If you want to program the AVR you can use the ARDUINO software bundle or the stino to upload the programs. You need to know c(only basics).
