eZdsp F2812 Tutorial
The purpose of this lab is to learn how to prepare Spectrum Digital's eZdsp F2812 to implement a finite impulse response (FIR) filter using an audio input. Since the F2812 does not have a digital-to-analog converter (DAC) as one of its peripherals, this lab will cover setting up the eZdsp to use two options: The eZdsp F2812 allows users to determine if the TI TMS320F2812 digital signal processor (DSP) is suitable for their application requirements. It also enables evaluators to develop and run software for the F2812 processor using Code Composer Studio. A separate tutorial for the Code Composer Studio software will be available in this course. To begin this lab, several tasks must be accomplished to set up the hardware before programming the DSP. Some background information has been provided, but additional information can be found in the References section at the end of this lab. The eZdsp requires a 5V power supply that is provided and should be connected to the board via connector P6. The supplied parallel cable also needs to be plugged into a PC with Code Composer Studio installed.
Soldering Connectors: Since the analog-to-digital converter (ADC) and the serial peripheral interface (SPI) on the eZdsp S kit will be used, two connectors need to be soldered onto the board. One header should be soldered onto pins 20-26 on the outline labeled P8, which deals specifically with SPI signals. The second header should be soldered onto pins 2, 4, 6, 8, 10, 12, and 14 on the outline labeled P9, where the analog signals are located. TI's multi-converter evaluation module (EVM) is a kit that allows users to evaluate the performance of several devices in the multipurpose (MP) family of data converters. It is designed to work with the TMS320 DSPs and comes with six different ADCs and ten various DACs. For this lab, the TLV5638 dual 12-bit DAC will be used.
Setting up the EVM: The EVM has a header labeled J11 that must be connected to header P8 on the eZdsp board. Using wires, connect the relevant headers. Once the boards are connected, the next step is to power up the EVM board. The EVM operates on four voltages: -12V, 0V, 12V, and 5V. Solder one wire to each pin in connector J7. After partially stripping each wire, use a power supply source to deliver the proper voltage to each pin. The D1 LED should light green when done correctly. Since a DSP will be used to generate signals, the EVM board must be configured accordingly. Ensure that the SW1 switch on the right side of the board is set correctly.
Another option for using an external DAC is the audio processing daughtercard, which was designed after the eZdsp was successfully set up to communicate with the TLV5638 DAC on the EVM. The only preparation required for the eZdsp to interface with the audio processing daughtercard is to solder two headers to P8 and P9. After mounting the audio processing board on the eZdsp F2812, connect the power supply and parallel cable to the eZdsp. The LED labeled 'Power' on the daughtercard should light up bright orange if done correctly. Additionally, connect the provided speaker to the jumper labeled 'R_SPKR' on the daughtercard, ensuring the black wire is connected to the '-' and the red wire is connected to the '+'.
For this lab, an Apple iPod will be used to supply the audio source, which must be connected with the supplied cable to the jumper labeled 'J4' on the daughtercard. Since the iPod does not have a reliable battery, it should be connected to a power supply. The setup should be organized accordingly.
Controls: The daughtercard features two potentiometers that will be programmed later in this lab to control the volume of the output signal and the spectrum of filters that will be applied to the input signal. In this part of the lab, Code Composer Studio will be used to implement the software for the FIR filter on the audio signal. For those unfamiliar with Code Composer Studio, reviewing the ELEC 424 tutorial before beginning is recommended. Several peripherals and interfaces will be utilized, and background information will be provided for each. For further information, refer to the References section at the end of this lab manual. The serial peripheral interface (SPI) is a high-speed communication protocol utilized in this setup.
This comprehensive setup involves careful soldering of connectors, proper voltage supply connections, and the integration of both the audio processing daughtercard and the EVM to facilitate the implementation of the FIR filter. The use of Code Composer Studio for programming ensures that the DSP can effectively process audio signals, allowing for real-time audio filtering and manipulation.The purpose of this lab is to learn how to prepare Spectrum Digital`s eZdsp F2812 to implement a finite impulse response (FIR) filter using an audio input.
