Hello,
I am trying to access the SRAM on an AD9102 and I’m having some issues. All of my reads for the SRAM return 0x0000 and the other questions in this forum haven’t enabled me to successfully read/write.
When I configure the device, I set the following registers:
When I try to load 4 memory locations into the device, I’m use the following sequence:
This seems to be correct and I can clearly see this going into the device using a logic analyzer. However, when I try to read the memory, I only receive 0’s. I am using the following sequence to read:
My setup uses the AD9102-EBZ and I am driving the signals with an external microprocessor. ( The SPI signals have been disconnected from the microcontroller located on the dev board.) Since I am able to read/write the registers, I’m certain that the device is hooked up properly and the system is properly functioning, but I can’t seem to get the SRAM to respond. Any suggestions?
