Frequently asked questions
What is the Stellaris migration path for new designs currently targeting the LM3S818?
TI positions the Tiva C Series TM4C as the Stellaris successor family. Migration involves toolchain updates (StellarisWare to TivaWare/SimpleLink), potential pin-out changes depending on which TM4C variant is selected, and firmware recompilation. Pin-compatible replacement is not guaranteed across families — treat it as a design port, not a socket swap.
