Software implementation of a fully buffered, full-duplex, interrupt-driven serial port driver that can be used with either or both on-board serial ports. Also included is a modified version of IFI's printf() software that supports the use of both serial ports. Unlike the IFI code, this driver is non-blocking, which means that you can send a byte of data without having to wait around to make sure it gets sent before sending another. This is the same way operating systems, like Linux and Windows, handle serial data reception and transmission in the background for application software. Version 0.3 and later is designed to be compatible with the new output stream functions built into the Microchip C18 2.4 compiler. Continue using version 0.2 if you're using C18 2.3 or earlier. Because you can now easily receive data from another computer, you can interact with your nifty IFI robot controller in real-time to change operating parameters on-the-fly using common terminal emulation software, or send real telemetry to custom applications written with Visual Basic, Visual C++, MATLAB, etc... Don't want to drag a long serial cable behind your 'bot? Well, check-out the nifty SMiRF radio modem from SparkFun Electronics. Would the coolness factor of your 'bot be elevated if you had a LCD mounted on board to display diagnostics (yes, this is a rhetorical question)? How about using one of the serial LCDs that can be found on the 'net? I've been using Scott Edward's Electronics serial LCDs with success. Disclaimer: Other than being a satisfied customer, I have no interest (financially, or otherwise) in the companies mentioned above. |

| frc_adc.zip | Example driver and supporting software to setup and run your robot controllers analog-to-digital converter in the background. A few advantages of using this software include parallel, non-blocking operation of the ADC hardware, precise control over the sampling period, which is important for signal processing and control applications and the ability to make more precise measurements using oversampling. Updated 12/15/05. |

| frc_encoder.zip | Example driver and supporting software that can be used to interface two quadrature output optical encoders to the IFI FRC robot controller. Updated 1/2/05. | 212,830 |
| frc_accelerometer.zip | Example driver and supporting software that can be used to interface a Texas Instruments accelerometer to the IFI FRC robot controller. | 408,297 |
