Hello,
Everyone, I am doing my project to make a MP3 based on MSP430G2553. And so far, I've successfully operate decoding module based on VS1003 chip and SD card module. Both of them are seperated into two different files. While when I combine them into one file and do single step, this error happened.
Plus, the first module uses USCI_A SPI mode and the second module uses USCI_B SPI mode. Both of them have different ports.
