KM34Z128 uart config for 300bd 7E1

raja_m — Tue, 04 Jun 2019 10:10:49 GMT

I used KM34Z128. it is working 300 bd and 8N1. but not able configure 7E1 mode. how to configure 300bd 7E1

UART3_Init(UART_MODULE_INTRMODE_CONFIG1(SET_300_BR,SystemState.SysClk));
UART_InstallCallbackUART2_UART3(UART_INTERRUPT_PRIORITY, OpticalEventHandler);

Hi Raja M,

Please check snippet below. 7 bit data is not supported, you can only set 8 or 9 bit data by setting M bit in the UART_C1 register.

Have a great day,
Felipe

Hi Felipe García

May it will support (7E1)7 bit data,1parity and 1stop bit

UART_C1 register - if i enable SET(UART_C1_PE_MASK) ,7E1 should work but for me not working why? any other configuration need?

Hi Raja,

By checking your code above I see you are not setting Parity Enable bit in the in the UART configuration.

Could you please try as below?

#define UART_MODULE_INTRMODE_CONFIG(brate,bclk) \
(tUART){ \
/* BDH */ CLR(UART_BDH_RXEDGIE_MASK)|((CALC_SBR(brate,bclk)>>8)&0x1f), \
/* BDL */ ((CALC_SBR(brate,bclk)>>0)&0xff), \
/* C1 */ CLR(UART_C1_LOOPS_MASK)|CLR(UART_C1_RSRC_MASK)| \
/* .. */ CLR(UART_C1_M_MASK)|CLR(UART_C1_WAKE_MASK)| \
/* .. */ CLR(UART_C1_ILT_MASK)|SET(UART_C1_PE_MASK)| \
/* .. */ CLR(UART_C1_PT_MASK), \
/* C2 */ CLR(UART_C2_TIE_MASK)|CLR(UART_C2_TCIE_MASK)| \ ...
...

Hope it helps!

Best regards,

Felipe

Hi Raja M,

Could you please try one of our examples and modify the SET(UART_C1_PE_MASK) register?

You can find the examples in the following link:

https://www.nxp.com/downloads/en/lab-test-software/TWR-KM34_DEMO_SW.zip

Are you configuring the terminal to receive the parity correctly?

Please let me know your findings.

Best regards,

Felipe

Hi Felipe García,

modified the SET(UART_C1_PE_MASK) but it is not working. Please give me valuable support.

Hi Raja M,

Please accept my apologies for the late reply. I did the following testing to work with 7 bits data and odd parity and it worked well.

I am using TWR-KM34Z50MMV3 board (KM34Z128 MCU same as yours) and I used the uartisr_test example you can download from https://www.nxp.com/downloads/en/lab-test-software/TWR-KM34_DEMO_SW.zip

I modified this example by configuring UART_C1[PE] | UART_C1[PT]. This were the only changes I made, please see attached the modified header file.

I configured the serial term as follows:

Using this I got the following behavior:

As you can see TX and RX worked correctly with 7 bits data and odd parity.

I hope this helps you.

Best regards,

Felipe
