c - What is the progmem equivalen for ARM Cortex M0?

Question

I want to store my data array in flash, so I am doing const table[TABLE_SIZE] = {};. When working with AVR, I remember I used the PROGMEM attribute. Does using const do the same as PROGMEM or is there a way to use PROGMEM in my M0?

Answer 1

使用static const. 这并不是它的确切含义，但大多数嵌入式编译器会将其解释为他们应该将表留在 ROM 中（而不是向 RAM 添加副本）的标志。请注意，您需要在静态初始化程序中实际初始化它：您不能{}在运行时使用和初始化它。
