Hi PRena.1,The ST25RU3993 chip has an SPI connection for communication between the MCU and the Reader IC and using an GPIO input on MCU side to connect its IRQ line to the MCU. This GPIO is configured to catch the IRQ and calls then the ISR in the FW...
Hello chaiwat,can you provide further details what SPI commands you send. Could you send digital traces from your SPI communication ?You could also have a look into the FW for more details how the PLL is configured, the power modes are set proper an...
Hi PRena.1do you run the FW with STUHFL_DEVICE_MODE and do you want to do batch command processing ?when looking to your call stack I think the reason for your hard fault is that batch mode is enabled for your inventory.This can be enabled/disabled w...
Hello,yes you can use an ESP32 board to drive an ST25RU3993.The HW requirements to operate the ST25RU3993 Reader IC is at least an SPI interface and one GPIO pin to detect IRQs transmitted by the ST25RU3993.Please have a look at the following ST Comm...
Hello,not sure whish board you have. The as3993 is an older version of ST25RU3993.For ST25RU3993 based boards you could use the ST Reader Suite GUI for ST25RU3993 based boards.After download the GUI and connect to an ST25RU3993 HPEV board you can gen...
