Codespot Dev
Low-power DSP box for the development of audio player applications
Codespot Dev is based on the audio codec VS1063 by the Finnish manufacturer VLSI Solution. The DSP box has two galvanically isolated digital inputs enabling it to react to external contacts or voltage. Two digital outputs, likewise galvanically isolated, can be used for the control of external devices. Two 3.5 mm jack plugs provide a stereo line input and a stereo line output, whereby the latter is also suitable as a headphone output.
Audio and other data files can be exchanged directly between a PC and a microSD card in an internal cardholder via an integrated USB to SD card bridge. Furthermore, a serial flash memory is available for saving firmware.
Programming and in-system debugging occur via an RS-232 interface. This can also be used by the application to communicate with external devices.
The development of firmware mainly occurs via the free IDE from VLSI Solution, which has preconfigured plug-ins and examples for Codespot Dev. Among other things the source code of an audio player is available which is well suited as a basis for one’s own applications.
