Hello people! I am working on a project where I need to use LMS filters module of CMSIS and GPIO and USART drivers of STM standard peripherals library. The GPIO, TIMER and USART drivers are working fine. The LMS example in CMSIS folder also compiles without any error, however, if I try to 'call' GPIO or USART drivers from STM standard peripherals library in CMSIS example, I get a lot of errors while compiling. Can someone please tell me what am I doing wrong? The device is STM32F4 Discovery Kit.
