Force FTDI FT232 USB to serial converters to use a single Windows COM port

Ever notice that each new FT232 inserted into each USB port is assigned a unique COM port number under Windows? When we’re developing hardware with lots of prototypes flying around Windows quickly hits COM 100. Each FT232 has a unique serial number and the driver creates a new COM port for each by default. FTDI […]

App note: USB current meter using the SPI Interface

Here’s a Multi-Protocol Synchronous Serial Engine (MPSSE) implementation from FTDI. This application note gives an example of using the Multi-Protocol Synchronous Serial Engine (MPSSE) on the FT232H device. It uses D2xx commands to configure the MPSSE to interface with two Analog to Digital Converters (ADCs) using the Serial Peripheral Interface (SPI). It is controlled by […]

App note: USB hardware design guidelines for FTDI ICs

Check out hardware design guidelines from FTDI when using their ICs. While use of FTDI ICs makes USB easy to implement, care must be taken during the hardware design phase of a project to ensure certain practices are followed. This application note provides design guidelines for several common questions that have been asked of the […]

Buspirate issues solved?

Recently the forum is flooded with people that are experiencing troubles with the Buspirate v3.6. Pieter in the forum was no exception. He first tried the Buspirate on his Windows 8.1 and Vista machine and went to the forum after finding out hise buspirate didn’t respond to anything. The supportteam in the forum suspected the PIC was not programmed or […]

Open hardware USB to RS485 adapter

Ethan Zonca of Protofusion writes: While developing the Luma RS485-networked LED driver we discovered a need for a small and inexpensive USB to RS485 adapter. We designed an adapter with a FTDI basic UART chip (FT230XS) and an inexpensive TI differential receiver (SN75176). Our small selection of parts brings the cost down to just over […]

Simple 50+ kHz logic analysis with ATtiny2313 and FTDI friend

Joonas Pihlajamaa over at Code and Life  writes: While banging my head against the wall with debugging my PS/2 keyboard thingy, I really wished I had a dedicated logic analyzer (preferably with PS/2 decoder, but even raw binary data would’ve been fine). So I decided to try out a long hatched idea – combine an […]
