The microDAC that is easy to develop in windows and linux with our included demos!

The techFX microDAC utilizes Microchip's new PIC 18F14K50 low pin count USB MCU. This MCU has a great featurelist and has allowed us to pack most of those features into a very small footprint of 1.5" x 1.2" pcb!!

With 12 bit DAC on 2 Channels, and 10 bit ADC on configurable pins, you can use this small controller for both A2D and D2A applications. The DAC is on an SPI bus as is the 256K eeprom--which allow for wavetable usage and high speed operation. 

The Controller can be USB powered, or self powered through the LDO - Low noise Voltage regulator.

Accessories such as TTL / Analog inputs / PWM / INT pin / and serial UART make it a versatile controller.

Software framework

The Controller comes with both Windows and Linux frameworks.

The Windows framework consists of HID firmware and a windows interface. HID USB drivers don't require drivers, so using them is much easier than regular USB devices!! The Source is in Visual C++ with Net 2.0.

  The Linux framework consists of LIBusb firmware and a QT3-QT4 based interface developed on Ubuntu Linux. The Latest version of Ubuntu Linux (9.04) has most of the libs required to run this without installing any additional drivers to recognize the microDAC controller. The interface can be developed further using QT3 or 4,G++ (GCC), and LIBusb. The demo interface is as follows:
