I want connect ad7264 (in software mode via spi) to aduc7128. But I found problems
1. SPI module in aduc7128 work transmite only 8/16/24/32 bits . But ad7264 required 33 /47 bits.
2. If i write software spi, it made slow...
The SPI only can transfer Bytes, so there may be no other solution than a software SPI.
But I did have a quick look into the AD7264 datasheet and it may be of no problem always to use 48Bit,
You should read the datasheet of AD7264 in detail again and may try this or ask this question in the ADC community.
