Hello,
I'm using ADS1271, data rate 1 KHz, SPI interface. Most of my samples are correct but quite often I read one of these:
- samples with most significant byte sent twice (first and second byte are the same)
- samples with every one of my threee bytes shifted by some bits (for example I read 00000110 instead of 00011000)
I had a look with the oscilloscope and it appears as if the serial interface (CLK, SCLK, ...) is always the same.
Other details: supply and reference are correct, clock frequency 10MHz (crystal clock witha 50ohm series resistor), SCLK frequency is 2.5MHz.
I tested high-resolution, high-speed and low-power modes
Thanks for your help.
