Description:

Home | Download | License USBula - Serial to USB-Flash-Drive Bridge Firmware USBula is a ready-to-use firmware
accessing USB flash drives from your application
over a simple serial protocol.
USBula User Manual USBula FREE edition License USBula

Features

Connects USB memory stick to your application without USB programming Ready to flash binary files (HEX format, supported by most programmers) Runs on well available PIC24FJ64GB002 microcontroller (on stock part from many distributors) Free version for evaluation and personal use Source code available (via license option) – modify it for your needs +5V tolerant serial interface with simple protocol for file access FAT16/FAT32 is supported. 8+3 character filenames are used.

Typical application

The PIC24F is designed into the application. It is programmed with USBula firmware. For a circuit example and design hints, please see the USBula User Manual, section "Integration Guide".

Evaluation Board

An evaluation board preprogrammed with USBula firmware is available: USBula EB Datasheet Order USBula EB now! € 37,90 incl. 19% VAT excl. € 4 shipping.

Example

Serial.print("U\n");             // sync (baudrate detection)while (Serial.read() != '\n');   // consume responseSerial.print("O1A:test.txt\n");  // open file (id 1, append mode) while (Serial.read() != '\n');   // consume responseSerial.print("W10b\n");          // prepare write of 11 bytes while (Serial.read() != '\n');   // consume responseSerial.print("Hello World");     // write data to file while (Serial.read() != '\n');   // consume responseSerial.print("C1\n");            // close filewhile (Serial.read() != '\n');   // consume response

"Hello World" is written to the file "test.txt" on the USB stick. The code is shown in Arduino style (see whole Arduino USBula example), but any other programming language or host system can be used to communicate over the UART with USBula.
