ZIGBEE RGB应用的问题

8258的芯片，RGB应用， lookup table 什么意思?




#if defined(MCU_CORE_826x) || defined(MCU_CORE_8258) || defined(MCU_CORE_8278)
    //lookup table?
    return;




另外 pow是什么功能，找不到
r = (r <= 0.0031308f ? 12.92f * r : (1.055f) * pow(r, (1.0f / 2.4f)) - 0.055f);

"lookup table" - obviously Telink didn't create one so it doesn't do anything. You probably need a lookup table due to the maths needed to calculate, which TLSR8258 can't do. You could probably create a lookup table yourself.

pow() - is a standard C function that raises a number to the power of another number.

1. pow(double base, double exponent);

好的，只是8258如何解决这个问题？

I guess it doesn't solve it. Telink left it to you (developer) to work it out.
