/* by Joseph Ellsworth CTO A2WH. Freeuse for all. No promises, No warranty * Please contact us http://a2wh.com for help with custom design projects. Most STM and Freescale ARM chips include a unique Serail Number embedded in the CPU. This is a perfect number to use in IoT as a SSID. I use this to produce the WIFi SID so I can walk up with a phone and download telemetry. I found a blog discussion for mbed that suggested using the MAC but this assumes mbed hardware whereas this version uses the serial number built in to the CPU so it should work on native boards. */ #ifndef uniqueCPUID_h #define uniqueCPUID_h #include "mbed.h" #define uniqueSerialAdd_kl_freescale (unsigned long *)0x40048058 #define uniqueSerialAddr_stm32 (unsigned long *)0x1FFFF7E8 //TODO: Add logic to detect the different boards and select the correct // CPU ID based on the active board. #define uniqueSerialAddr uniqueSerialAdd_kl_freescale // Change to enable for address for your chip family // Note some ealry stm L3 chips were produced with all // chip ID set to FFF.
