Hi,
I am trying to setup UART1 communication on the LPC4357 device. This is the first time I am using an ARM device, I usually use AVR ATmega devices. Now, to setup an I/O stream, I used
(line 12) FILE *UART_STR = FDEV_SETUP_STREAM(UartPutChar, UartGetChar, _FDEV_SETUP_RW);
and then later on,
(line 24) stdout = stdin = UART_STR;
But this is not working as the IDE gives me the following errors
Driver.c(12): error: #20: identifier "FDEV_SETUP_STREAM" is undefined Driver.c(12): error: #59: function call is not allowed in a constant expression Driver.c(12): error: #20: identifier "_FDEV_SETUP_RW" is undefined Driver.c(24): error: #137: expression must be a modifiable lvalue Driver.c(24): error: #137: expression must be a modifiable lvalue
Apparently, the stdio.h library in Keil does not have this macro defined unlike the AVR library. I do not know of anything else to make my code for the UART setup work, as I need to setup an I/O stream.
So, I'm wondering if someone knows how I might fix this issue in Keil and get my code to work. Please help me with this matter!
Thank you. -Jameel
