Giovanni Carrera writes, “This project uses a serial 40×4 LCD display with a Teensy board to realize a compact serial terminal receiver to be connected to many systems with serial output such as our microcontroller systems and GPS receivers.” More details at ArduPicLab blog.
Dilshan Jayakody published a new build, USB to 3.3V – 5V serial TTL adapter: This post is about experimental USB to 3.3V/5V serial TTL adapter which we build recently to work with both 5V and 3.3V MCUs. This project is mainly based on CH340G seral-USB chip. CH340G is cheap and commonly available serial-USB convert IC […]
Jan Cumps tested out SPI Protocol using a Bus Pirate: It wasn’t my initial intention to use the Bus Pirate. But my first naive attempts to talk from Hercules to EEPROM failed. I could create the SPI instructions with the LaunchPad, but I didn’t get a reply back from the 25LC256. It’s in these cases that […]
microtherion has published new project the ChipHeadBang, that is available on Github: Design for an USB to Serial converter with ICSP header for (slow) bitbang programming, based on the CH340G chip. While this seems to work pretty well, and the CH340G can be obtained extremely cheaply from sources such as AliExpress, driver support can be a bit […]
Ray Wang has been experimenting with the ESP8266 Serial-to-WiFi module, which has gained much hype recently. “The module is very compact, easy to interface with, and inexpensive. I wrote an Arduino program to show how to use the Arduino to communicate with the WiFi module and set up a very simple web server.” Check out […]
Abstract: Many embedded applications share information with external devices, and the preferred connection between devices is asynchronous serial communications. The multicore architecture of the P8X32A enables the designer to create and deploy device-to-device communications strategies with no impact on the primary application code. In this example a deployed communications support cog manages data between the […]
Bored of always typing in the same password over and over again? Luca designed a board to tackle just that problem. It’s a USB composite device, featuring both a USB keyboard emulator and a serial port. You program the letter sequence for the keyboard to type via the serial port, then press a button on […]
MegunoLink is a utility to create a communication link between PCs and serial port devices such as the Arduino. … useful tools that interact with an Arduino-style board (or other MCU with serial data). The software is called MegunoLink, from BlueLeafSoftware in New Zealand. Megunolink has many useful features, and we’ll run through them briefly […]
Kevin entered a Detailed consumer IR capture with 74HCxx series chips for the Open 7400 Logic Competition: This is a CIR (Consumer IR / Remote Control) capture device built with 74HCxx series logic chips. It allows a computer to do a detailed capture with carrier frequency, on/off durations, and on duration pulse counts. Via the […]
Chandler has posted this tutorial on Interfacing Arduino and Python as it relates to serial programming. For this tutorial, you will need (or at least it is helpful) to have a knowledge of the Python programming language. You will also need an Arduino, and other components depending on how many of the four projects you […]
The MCP2200 is a new USB to serial converter chip from Microchip. Our MCP2200 breakout board brings all the pins to bread board friendly headers. USB CDC virtual serial port interface Secondary HID configuration interface Up to 8 additional IO 256bytes user EEPROM TX/RX indicator LEDs All pins to bread-board friendly header Open source (CC-0) […]
The tiny TK-1315LA GPS tracks up to 20 satellites, and runs from battery-friendly 3.3volts. Tayken demonstrates how to connect the Bus Pirate and get NMEA position data from the device.
This is a preview of an inexpensive, medium-speed AVR/PIC/CPLD/Arduino programmer. It’s designed for people who don’t own a programmer and just want to rescue a bricked PIC or AVR. The programmer uses the bitbang mode of a FT232R FTDI USB->serial converter chip. The same one used on the Bus Pirate and Arduino. There’s existing apps […]
Edouard Lafargue let us republish his demonstration of a Noritake GU140x32-7002 Serial VFD screen (may prompt about a secure certificate). The Noritake VFD used here is a “Show and Tell” 140×32 semi-graphical VFD. This display has the big advantage of being able to display graphics and manage so-called ’user windows’, making it a good choice […]
Mike Donovan suggests that a USB version of Zibri’s Force Trainer interface hack could be done with a Bus Pirate. Substitute the MAX RS232 serial converter with a Bus Pirate in UART mode configured for 57600, 8/N/1 : “call it Bus Pirate Mind-Reading Mode”. View output in the terminal, or start the transparent UART bridge […]
The logic analyzer output above (top continues on the bottom) shows the Bus Pirate I2C address scan function. The Bus Pirate sends a DS1307 I2C read address. After the DS1307 ACKnowledges the address (bit 9), it immediately starts sending data to the Bus Pirate and ignores the I2C STOP sequence sent by the address scanner. […]
