1 This code repository is a work in progress. The initial objective is to move 1 The present package is a set of tools for working with USB-serial interface
2 FTDI EEPROM tools out of freecalypso-hwlab Hg repository and polish them into 2 chips, specifically those FTDI and Silabs chips that are of relevance to
3 an installable software component similar to other FreeCalypso tools; I am also 3 FreeCalypso. The following tools are included:
4 looking at the possibility of developing some tools for old-style CP2102 chips 4
5 that require EEPROM tinkering in order to switch between 230400/460800/921600 5 * Utilities for examining the non-volatile baud rate configuration on CP2102
6 and 203125/406250/812500 baud rates. 6 adapters and for reprogramming their EEPROM, switching between "standard"
7 230400/460800/921600 and GSM-specific 203125/406250/812500 baud rates;
8
9 * A utility for switching a FreeCalypso DUART28 adapter between C and S
10 configurations, as well as checking the current configuration;
11
12 * General-purpose FT2232x and FT232R EEPROM programming tools.
13
14 The common theme across all of these tools is that they talk to a USB-interfaced
15 chip at the native USB level, bypassing the usual abstraction of ttyUSB, and
16 thus require libusb. More specifically, our tools are built on libusb-0.x API,
17 consisting of <usb.h> include header and -lusb link library pull-in; on "modern"
18 systems these pieces will typically be provided by libusb-compat-0.1 package
19 wrapping around libusb-1.x, but in the spirit of Holy retrocomputing, really old
20 systems can be used with native libusb-0.1.
