Posted on November 02, 2007 at 14:12Hello all,
I'm newbie in ARM microcontroller :) and I'll be pleased if you could help me with my first program.
In order to enable UART1, the code I write is:
GPIO_Config(GPIO0,0x0800,GPIO_IN_TRI_CMOS);
GPIO_Config(GPIO0,0x0400,GPIO_AF_PP);
UART_OnOffConfig(UART1, ENABLE);
UART_FifoConfig (UART1, DISABLE);
UART_FifoReset (UART1 , UART_RxFIFO);
UART_FifoReset (UART1 , UART_TxFIFO);
UART_LoopBackConfig(UART1 , DISABLE);
UART_Config(UART1,9600,UART_NO_PARITY,UART_1_StopBits,UARTM_8D);
It returns to me an error: Undefined External RCCU_FrequencyValue refered in UART...
What is worng? Do I need to add something else?
Please help me.
Best regards.
Alfa
