Aug 09, 2012 · Without the EEPROM, the FTDI device will work as a USB <-> UART, you need the EEPROM to select other configuration (like 245 FIFO, MPSSE, etc) The USB <-> UART configuration can be used in a bit-bang fashion (i. Host: Linux PC, Ubuntu 14. The power consumption is measured with the on-board PMBus, a bus based on I2C that enables to read the power directly from the on-board power converters. You should be able to highjack it the same way I have in these instructions, but may have to investigate which pins using a datasheet. 04. Every port is equipped with an engine called a Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify a synchronous serial protocol (USB to JTAG, I2C, SPI, or bit-bang) design. The connector is oriented with pin 1 beside the USB connector, and pin 40 next to the reset button. Note that you have to run it as root (or join some or other USB group), otherwise the USB device will not open. The Bus Pirate allows the communication between a PC with a USB connection and any chips through serial protocols like I²C and SPI. I installed pylibftdi with pip3 and when trying examples I always get a segmentation fault when initializing the device.
