Hi,couple of questions-how long it takes from where the CR95HF reads the data correctly until it sends the data to the MCU (over UART)? let's say it's 10 Bytes user data.when reading multiple blocks- does the CR95HF read single block by single block...
i try to use the nfc reader cr95hf (MIKROE-143) since a few days. as mcu i use the evaluation board nRF52832. unfortunately i don't succeed so far.The data sheet for the MIKROE-143 can be found here:https://www.mouser.ch/datasheet/2/272/rfid_click_ma...
Hi, I'm new with STM32 MCU.While i was following the tutorial in USER MANUAL, i faced communication error and i don't know why.I installed USB Driver, so here the USB PORT is fine with COM7.However, usb software can't detect my BOARD. here is the cap...
I am using STM32. I can read the NDEF file from M24SR via I2c but I want to to delete it after reading so do I erase? I didn't found any example of erasing in app note.
I'm trying to use the X-CUBE-NFC5 Code in an freeRTOS Project. With only one Task it works well, but when i try to add an other Task it does not. Depending on Task priorities the demo cycle is still working but all other tasks are starving or it even...
