大家好,
在MTK平台的校准文件里,
有一个CFG文件:
[TX PCL table]
GSM850_MAX_P = 6, 8, 10,12,13.8,15.8,17.8,19.8,21.8,23.8,25.8,27.8,29.5,31,33,
GSM850_WANTED_P = 5,7,9,11,13,15,17,19,21,23,25,27,29,30.5,32.5, [/COLOR]
GSM850_MIN_P = 4,6,8,10,12.5,14.5,16.5,18.5,20.5,22.5,24.5,26.5,28.5,30,32
GSM850_C = 3,3,3,5,5,5,5,5,5,5,5,5,5,5,5,5,
GSM850_CORRECTION = 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
有一个INI文件:
[GSM850 level, ramp]
APC dc offset=125
Low APC dc offset=0
APC lowest power=5
TX power level=48,55,64,74,86,101,119,141,169,204,247,303,373,437,544,544[/COLOR]
profile 0 ramp up=0,0,0,0,0,0,0,0,48,92,150,170,200,255,255,255
profile 0 ramp down=255,253,243,197,113,0,0,0,0,0,0,0,0,0,0,0
请问这两个文件中的两段蓝色粗体代码,对控制各个Level的功率作用有什么区别?
如果我要提高GSM850 Lev5的Max Power,除了修改CFG文件中的GSM850_WANTED_P代码,INI文件中的代码需要修改吗?

不需要
修改CFG文件中的期望值即可
如果余量足够的话就可以不用改。
可以把ini 文件中对应的 digit 值调大
不需要改INI,INI中的值是校准的DAC初始值,校准时根据CFG的功率调节DAC的值,然后写入NVRAM中。
