I can see in the example firmware that the TID memory is read in multiple stages, with the first 8 bytes read first. In my application I need only these first 8 bytes, so following a very similar process I can read these bytes. I am working with a CR...
I have ST25RU3993-EVAL with FW v1.5.6 and I would like to update it to the v1.6.6. I can't do it through the ST25RU3993 Reader Suite. Every time I get "Update firmware failed". What should I do?
When trying to frequency hop on the main PLL, I observe a lock time of ~150ms. This seems quite high and I can't find any more information in the datasheet on the matter. Is anyone able to verify the PLL lock time?
I am able to read the tag but the rage is very less. Are there any gain settings to be changed the software. I am enabling external power amplifier still i am getting very less range. Please suggest me which type of antenna is better to use. What wil...
While developing a driver for the ST25RU3993, I have encountered a problem where the MISO line appears to stop working. I had previously been able to read out the version ID register, oscillator status, etc. but now everything reads back as zero. T...
