I am trying to set up UART on a LPC54102J512BD64, when I try to call RingBuffer_init, Chip_UART_SendRB or Chip_UART_ClearStatus I get the error "No Mathcing function for call to 'RingBuffer_Init' etc. There appears to be errors in ring_buffer.h and uart_5410x.h but I cannot edit these headers. Why would this be happening and how can I fix it? Thank you for any help!
