DirtyPCBs based project: Isolated USB Serial Interface

Wednesday, June 24th, 2015

Steve Rodgers just completed another project using a DirtyPCB order, an isolated USB serial interface, that is available at Github: Here is another project I just completed using a Dirty PCB order. It's an isolated serial port using the CH340G chip and 4 Silicon Labs Si8410 digital isolators. Isolating the...

Use the TP-Link TL-WR703N to send Arduino sensor data

Sunday, July 14th, 2013

Recently we highlighted the TP-Link TL-WR703N in a post. Some makers have used a WiFi shield to allow an Arduino to communicate with this router, and others have used the router's PCB as a shield bridging Ethernet to Wifi. Martin wanted to interface an Arduino with the router directly, so...

WORKSHOP VIDEO #28: Exploring the serial port

Thursday, July 5th, 2012

[embed]http://www.youtube.com/watch?v=6grUGkShWJE[/embed] While USB is all around us, the humble (virtual) serial port is still everywhere. Today we explore the serial interface on the Infrared Toy, Bus Pirate, and Logic Sniffer. See a demonstration of the binary interfaces and commands normally used only by software utilities. Grab some terminal software like Tera...

Control your Bus Pirate with an Android Tablet

Thursday, April 26th, 2012

N3mesys successfully controlled the Bus Pirate with an Android Tablet using the USB Serial Monitor app. This software lets Android enabled devices connect to FTDI USB-to-serial chips. The FT232RL and FT230X ICs are supported, so this works with older Arduinos and lots of other stuff with the common USB-to-serial chip....

Serial port monitor software

Wednesday, August 3rd, 2011

The crew at Adafruit remind us of a handy serial port monitoring tool for Windows known as PortMon. PortMon is an old school Microsoft utility used for monitoring all serial and parallel activity on a system. While USB rules the day for most PC-peripheral communications, PortMon can help when reverse...

Using the EUSART

Sunday, April 3rd, 2011

The term UART (Universal Asynchronous Receiver Transmitter) is the technical term for the good old serial port found on most MCUs. The term USART similarly refers to a serial port capable of handling both synchronous and asynchronous operation. Over the past few years, Microchip has been integrating an updated serial...

Convert the Chumby serial port into two PWM outputs

Tuesday, March 8th, 2011

Osman Eralp of Ozbots writes: When I was building my latest Chumby-based robot, I didn’t need the serial port, but I did want PWM signals to control the robot’s wheel motors. Fortunately, the processor pins that are used for the serial (UART) TX and RX pins are multiplexed with PWM...
