Hello,

I have an LPC1769 board connected with a LPCexpresso base board.

In the program mcc_fat, there is a uart_send message and I will check this with USB communication with PC (hyperterminal). I have communication but, I see nothing in the hyperterminal.

UART_SendString(UART_DEV, (uint8_t*)"MMC/SD example\r\n");

Or, how can I check this message with the base board?

Someone who has experience with the base board??

Hello

Have you tried to send text messages independently of you application? What "I have communication" means? The uart must be initialized before using it, and maybe you are using "semihost" mode, which in turn everything you send out will be displayed in the IDE's console.

:)

It's not independently, it's in the application code.

I have communication because if I put the usb in the pc he detects a COM-port.

What is de IDE's console??

Usb you say, so you must be using some kind of com->usb converter. If so, then the fact your computer detects a port means only your converter is working :)
