Secure 5 Click carries the ATECC508A cryptographic coprocessor with secure hardware-based key storage, from Microchip. The ATECC508A includes an EEPROM array which can be used for storage of up to 16 keys, certificates, miscellaneous read/write, read-only or secret data, consumption logging, and security configurations.

Library Description

The library demonstrates the operation of the software single wire interface implementation.

Key functions:

  • int8_t secureswi_init(T_SECURESWI_DIRSET inSet, T_SECURESWI_DIRSET outSet) - Initialize the SWI interface and pass the pin direction setting functions.
  • void secureswi_sendBytes(uint8_t len,uint8_t *stBuf) - Encode data buffer and send the data to the SWI bus.
  • void secureswi_receiveBytes(uint8_t len,uint8_t *stBuf) - Receive and decode data from the SWI bus.

Examples description

The application is composed of three sections :

  • System Initialization - Initialize the GPIO sturcture and configure the serial port for logging data.
  • Application Initialization - Initialize the driver and configure swi for communication.
  • Application Task - Data is read from the secure chip. If the readout is successful the data is then printed on the serial port in the hex format.
void applicationTask()
{
     uint8_t bufferOut[128];

     cfg_atsha204a_swi_default.iface_type  = ATCA_SWI_IFACE;

     }

         mikrobus_logWrite("rn Reading serial number failed...",_LOG_LINE);

     }

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

Tamper Click is equipped with SDS001, a low profile side-actuated detect switch, made by C&K company. This is a high-quality, low-current detection switch, which is designed in a form of a push button. The switch itself is very small - only 2mm of switch overtravel length, which coupled with its low actuation force, makes it ideal for using it as a contact detector in various applications - consumer electronics devices, medical devices, smart card detection and similar applications.
