Hi TI,
I am trying to read AD7768 by EK-TM4C1294. The data interface is a QSPI that has a Data Ready signal, DCLK and four Data lines.
I am trying to use ssi_quad_mode.c example from TI. Based on the TM4C1294 datasheet I think the Data Ready signal should be considered as SSInFss.
However, in the datasheet it is mentioned that I can capture 4 to 16 bit after SSInFss comes down while here I need to capture 32 to 64 bits before receive the next DRDY from ADC.
Do you have any suggestion that how I can read a QSPI with long frames like 32,64 or even more?
I am using TI-RTOS, but I have merged the ssi_quad_mode.c in my project. It is also possible if there is not any work around it I drop the RTOS and just write bare metal code but I prefer to kee it as the last option.
Best regards,
Mostafa
