专家:您好!
1.开发板和说明书,100Pin的MCU控制boot mode都是GPIO24和GPIO32,我现在使用64Pin的280041,也是用GPIO24和GPIO32吗?
2. MCU009A的案例中,我没有找到产生1.2V的LDO,是不是VREGENZ接地就可以使用的内部1.2V电压,那么VDD的端口是不是可以悬空,什么都不接?
Hi Fei Gao,
1. 是的,但是可以修改。看一下sprui33f_TMS320F28004x Real-Time Microcontrollers Technical Reference Manual (Rev. F)第590页;
2. 不是,需要接去耦电容:
