UART SIGNAL OF K60 TOWER

liwinter — Wed, 15 Nov 2017 07:55:16 GMT

I'm learning UART of PK60FN1M0VLQ12 resently,using the TWR-K60F120M. I think Ihave already configure the program of UART cause I can detect the signal:

also I think I configure the baud rate cause I can change the width of the wave，but my computer can't receive the signal .

I have consider the circuit connection ，so I connect the jumpers。but in datasheet PTB11 is configured as UART3_TX,

the signal then is transported to PRIMARY side .

and then the signal break off。

so how can I transport the signal to TWR-SER2's ICL3225E to change TTL to RS232 .

thanks for your help .

Best wishes

Hi 冬李，

1. What the UART pin you are testing which have the signal.

In TRK-K60F120M board, the on board virtual com port is connect to PTE9(UART5_RX), PTE8(UART5_TX), so in the code, you need to use the UART5, PTE9 and PTE8.

If you want to use the TWR-SER2's UART port.

According to the TWR-SER2'S schematic and the TWR-K60F120M schematic,

You also need to use PTE8 and PTE9.

Please check, whether you are using the correct pin in the code.If you need to use the serial board, you need to connect the J19 and J17 pin1 and 2.

Wish it helps you!

Have a great day,
Kerry
