I am reaching out to seek assistance regarding some challenges I am facing with the write and read operations on the SRAM of the AD9106 devices. I have thoroughly studied the respective datasheets (AD9106 datasheet, pages 22-23) but have encountered difficulties in achieving the desired functionality.
Specifically, I am experiencing issues with:
Writing data to the SRAM: Despite following the instructions provided in the datasheets (e.g., enabling the MEM_ACCESS bit in the 0x1E register, writing left-justified data to the SRAM registers ranging from 0x6000 to 0x6FFF, and disabling the MEM_ACCESS bit), I have been unable to successfully write data to the SRAM.
Reading data from the SRAM: Similarly, when attempting to read data from the SRAM, I have encountered difficulties despite enabling the BUF_READ and MEM_ACCESS bits in the 0x1E register. Disabling the bits after reading the data has also proven challenging.
I have thoroughly reviewed the datasheets, but it appears that I may be missing some crucial steps or misinterpreting certain instructions. I would greatly appreciate it if you could provide me with guidance and clarification on the correct procedure for performing write and read operations on the SRAM of the AD9106 devices.
If possible, could you please provide me with detailed step-by-step instructions, highlighting any potential pitfalls or commonly overlooked aspects of the process? Additionally, if there are any specific register settings or considerations I should be aware of, kindly provide those details as well.
I understand that your team has extensive expertise in working with these devices, and I am confident that your guidance will help me overcome the challenges I am currently facing.
Thank you very much for your time and attention to this matter. I look forward to your prompt response and assistance. I attached my code along with it
