How do I connect the Bus Pirate to a PC?
Connects the Bus Pirate to a PC. The Bus Pirate draws power from the USB port, and uses the data connection to communicate with the PC. 2. USB transmit indicator.
What do the lights on the Bus Pirate mean?
The Bus Pirate draws power from the USB port, and uses the data connection to communicate with the PC. 2. USB transmit indicator. This LED flashes when theres traffic from the PIC to the PC. 3. Power indicator. This LED lights when the Bus Pirate is powered by the USB supply. 4. Mode indicator.
What is the Bus Pirate UART header?
This unpopulated header is a tap into the UART connection between the PIC microcontroller and the FTDI 232BL chip that provides the USB connection. The Bus Pirate firmware defaults to a 115200bps/8/N/1 UART. Windows will request a driver the first time the Bus Pirate connects to a PC.
What is the speed of the Bus Pirate?
The Bus Pirate operates at 115200bps/8/N/1 on the COM port assigned by Windows. Flow control is no longer required. Disable it! Next, check the terminal setup.
How do I configure the Bus Pirate?
The bus mode menu (M) configures the Bus Pirate for a specific protocol, like 1-Wire, I2C, SPI, etc. The default start-up mode is HiZ, all pins are inputs and all power supplies are off. Most modes have additional options, like open drain outputs or speed settings. Each bus mode is documented in the Bus Pirate manual [1] . 1. Pullup off 2.
How do I use the Bus Pirate with vt100?
Turn off local echo and use a VT100 terminal type. The Bus Pirate should work with any type of new-line character, but we use the CR setting. The Bus Pirate is controlled by text commands entered through the serial terminal. If the terminal is blank, press enter to show the command prompt. Press ?, followed by enter, to show the help menu.
How do I set up I2C in Bus Pirate?
Press m in the Bus Pirate terminal and select I2C from the mode menu. Enable the power supplies (big W) and the pull-up resistors (p, option 2) at the I2C prompt. Get a voltage report (v) to make sure the power supplies are on and the Vpullup pin is connected to a voltage.
How do I enable pull-up resistors in Bus Pirate?
SPI doesnt normally require pull-up resistors. In the Bus Pirate terminal press m for the mode menu and select SPI. Configure the SPI library for normal pin output, use the defaults for all other SPI mode settings. Enable the power supplies (big W) at the SPI mode prompt.
How does a Bus Pirate work?
The Bus Pirate is a serial terminal bridge to multiple IC interface protocols. We type commands into a serial terminal on the computer. The commands go to the Bus Pirate through the PC serial port. The Bus Pirate talks to a microchip in the proper protocol, and returns the results to the PC.
What output format does the Bus Pirate use?
The output format is standard serial, but at 2.8volts it’s incompatible with PC serial ports. The Bus Pirate can interface this GPS without the need for a separate RS232 transceiver or 5volt power supply.
What is Bus Pirate Hi-Z Mode?
The Bus Pirate always starts in high impedance mode (Hi-Z), a safe mode with all outputs disabled. Its intended to protect any connected devices from conditions beyond their specifications. From there, a bus mode can be selected to use the Bus Pirate with a specific protocol.
What was the first USB bus pirate?
Bus Pirate v2go was the first USB Bus Pirate. Around 1000 were sold as a fundraiser for Hack a Day. The PCB is black. v1a and v0a were serial port Bus Pirate prototypes. Fundamental Logic briefly sold a through-hole kit for v1a.
