Dear NXP ,
I use KL02Z try to make a project with UART ( Polling method ) , IDE is code warrior 11.0 . Baud Rate is almost 9600
UART Sending data is normal . But Receive Data won't work , has already check PC UART Tool and waveform are normal .
Attachment is my code , could you help to point out what is wrong with this code ? thanks a lot !!
UART0_C2 &= ~(UART0_C2_TE_MASK | UART0_C2_RE_MASK);
UART0_BDH = 0x01 ;
UART0_BDL = 0x38 ;
UART0_C4 = 0x0F ;
UART0_C1 = 0x00 ;
UART0_C3 = 0x00 ;
UART0_MA1 = 0x00 ;
UART0_S1 |= 0x1F ;
UART0_S2 |= 0xC0 ;
UART0_C2 |= UART0_C2_TE_MASK | UART0_C2_RE_MASK ;
while(!(UART0_S1&UART0_S1_RDRF_MASK)); <------------ always wait here
String = UART0_D;
UART0_D = String ;
Solved! Go to Solution.
