Making it unrecognizable and inaccessible. The contents of the FTDI flash had been altered. You see, my first attempt at solving this problem, in reality, made things worse. Everyone was offering the same solution.īut, unfortunately, none of the information I found worked for my unique case. It soon became clear that the root of the problem was the FTDI USB-to-serial conversion chip. It had to be corrected before using the device again. This became another problem to be solved. My Nano started behaving that way when I pulled it off the shelf to help someone with a project. Look for cables that specifically mention FTDI.ĭo you have an Arduino Nano that is non-operational? Failing to upload sketches? Behaving basically as a dead device. The FTDI chip can add $10-15 to the cost of a USB programming cable, but will save time and frustration with driver issues. FTDI makes a high quality USB to serial chip that has a good, working driver built in to many operating systems. If a custom vendor ID and/or product ID or description string are used, it is the responsibility of the product manufacturer to maintain any changes and subsequent WHCK re. FTDI drivers may be distributed in any form as long as license information is not modified. FTDI drivers may be used only in conjunction with products based on FTDI parts. The Electronics Industries Association (EIA) standard RS-232-C as of 1969 defines: Electrical signal. It is commonly used in computer serial ports. In telecommunications, RS-232 (Recommended Standard 232) is a standard for serial binary data signals connecting between a DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment).
