I am starter.I don't now on which processor's vendor i will put my code. Can I design code for unknown vendor? I know that that is possible but tell me simplest way. I ask for Cortex M.I am woking in Keil4 and Keil 5
In general, if different SoC vendors use the same processor such as Cortex-M4, your code targeting at Cortex-M4 and compiled against Cortex-M4 can run successfully for all the SoCs. In this case, you can ignore the vendor information.
