We use dev. kit: ANT7-T-ST25DV64KC with app version: ST25NFCTap version V3.7.0 / ST25SDK: 1.10.0 public version. Q: I try to write binary data from file to it. I succeed in sending 4096 bytes. But when I try to send larger files it fails (tried 8192 ...

I am on STM32F401 and I want to measure PWM duty cycle (PWM input) with timer 3 and a DMA channel. I'd like to have the DMA to do several measurements and then calculate the average over it. My configuration is like this:My DMA config is like this:My...

After doing some reading/writing tests over I2C I found the "problem" myself. The NFC tag concerned is of size 64k BITS. For some reasons (bad reading) I assumed 64k bytes. 64kbits results in 8kbytes and that is exactly what I can read/write to it.

Yes, I just wanted to investigate if this is a possibility which can be used. If the DMA controller can do several measurements it can save a lot if IRQ's/context switching on the CPU. When the value is needed, let's say every 100ms (application cycl...

Cannot send larger chuncks than 4096 bytes to ST25DV64KC

Can I measure PWM duty cycle using DMA?
