Communication of double TMS320F28335 DSP Based on McBSP

Abstract

Abstract.A bidirectional real-time data communication without distinction between master and slave is achieved with double TMS320F28335 DSP using its multichannel buffered serial port (McBSP). The shortcoming of the communication on SPI mode that the slave cannot initiate communication is overcame. The hardware connection and the software realization plan of the scheme are detailed. Finally, tests on uninterruptible power supply (UPS) inverter prototype controlled by double TMS320F28335 DSP verify the reliability and real features of this design.
