The standard introductory program for nearly every microcontroller is the LED flasher, so let’s give that a try. ... I’m using FTDI RS232 usb converted. with VID=0x0403 and PID=0x6001.

Connect the USB side of this cable to a PC with the VPROG programming utility installed. Populate J4 to pull the PROG# pin of the VNCL1A low and temporarily short J3 to reset the device and put it ...

The answer is YES! AVR USBasp is a USB in-circuit programmer and it can use to program most of the Atmel AVR controllers. It simply consist of an ATMega8 and a couple of passive components such as ...

There are rumors of a cheap chip that does USB natively, has an Open Source toolchain, and costs a quarter. These aren’t rumors: you can buy the CH552 microcontroller right now. Surprisingly,… ...

As such, even hardware that was designed and specified as using proper FTDI chips could be affected. Every USB device has a pair of IDs. One, the Vendor ID (VID), is allocated by the USB group.
