Talk SPI to EEPROM part3: Test SPI Protocol with Bus Pirate

Tuesday, May 12th, 2015

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....

ChipHeadBang – design for an USB to Serial converter with ICSP header for (slow) bitbang programming

Monday, April 20th, 2015

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...

First impression on the ESP8266 serial-to-WiFi module

Monday, October 6th, 2014

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...

App note: Propeller communication with a PC app

Monday, October 14th, 2013

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...

Preview: Inexpensive multi-chip programmer

Wednesday, August 4th, 2010

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...

Demo: Noritake Serial VFD

Monday, March 1st, 2010

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" 140x32 semi-graphical VFD. This display has the big advantage of being able to display graphics and manage so-called ’user windows’,...

The point of I2C NACKs

Monday, August 17th, 2009

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...
