Hi

You can use DBG_vPrintf(TRUE, "Initialising ...");

Include the "dbg.h" file

hi 

thank you for answer, but I have use the UART0 for DBG, I want  use sprintf to combine string and transmit using UART1

Hi Liushuai,

You can set the DBG for the UART1 as well and transmit data.

You can not use the DBG for both UARTs.

Regards,

Mario
