I have some questions about LPUART1 of 'S32K142'.I use it with LIN transceiver 'ATA663211'. I use it to be master. My transmit function is right,but receive function is stranger. When I want to receive data form slave,I transmit head first.Then I receive data. ...
Solved: I'm using S32K148-EVB (nxp.s32k148evb-q176). I am testing the example to use uart, but the rx signal from lpuart1 is strange. * Connection:
I'm having issues receiving data on LPUART 0. Send works fine. Is my configuration correct, or what else might be going wrong? (Note the rx function is called 1 byte at a time at first as I am reading xbee frames). I am expecting to read the data in TX (see capture below). My...
I use code like this 'if(LPUART1->STS & rdrf mask) else if(LPUART1->STS & tc mask)' in the interrupt. The problem is when I want to transmit data,the rdrf is '1',so it do the receive work.I don't know how rdrf to be '1'. ...
