Is it a bug of the ADSP21065 serial port? To process data of the ADC AD7671 I have connected its SDOUT, SCLK, and SYNC pins to DR0A, RCLK0, and RFS0 pins of the ADSP21065L according to recommendation of the AD7671 Data Sheet. But 16-bits date words entered into DSP via SPORT0 looks as if the first two clock pulses of ADC have been missed. How Can I synhronize SPORT with ADC data? Can anybody help me to solve this problem? Thank in advance. |

Though the converters are different, (maybe the protocol are using is the same) try to look at this document: AD1819A_21065L.pdf You can find it at Analog ftp site (ftp.analog.com) . It explains how the AD1819A ADC converters works with ADSP21065L and how to solve symchronization problems with SerialPorts.
