Waiting for SPI RDY on LPC812 (Example_SPI0M_SPI1S)

jonaspistor — Mon, 12 Jun 2017 09:13:40 GMT

Hello,

I'm trying to run the SPI0M_SPI1S example on the LPC812 demo board.

It hangs in a loop waiting for the TXRDY flag:

while ((LPC_SPI1->STAT & STAT_TXRDY) == 0);

Debugger shows:

LPC_SPI1->STAT: 0b100010000

STAT_TXRDY: 0b10

Best regards

Jonas

Hi Jonas Pistor,

To provide the fastest possible support, I'd highly recommend you to refer to periph_spi demo in the LPCOpen library whose link is below.

Have a great day,
