I'm working on an LPC1113/302 (48-pin version), but SPI1 is not showing up in the peripherals. Is there some way of adding it?

Hi,

Please check the basic configuration in your software:

1) The SPI pins must be configured in the IOCONFIG register block.
2) In the SYSAHBCLKCTRL register, set bit 11 and bit 18 (Table 21).
3) Enable the SPI1 peripheral clock by writing to the SSP1CLKDIV registers
4) Before accessing the SPI blocks, ensure that the SSP_RST_N bit in the PRESETCTRL register is set to 1. This de-asserts the reset signal to the SPI blocks.

You can refer to the LPCOpen software

or the sample bundle code as a reference.

Thanks.

:quest:

I think he's talking about Peripherals View. There's no SPI1 available for LPC1113 LQFP48 versions...

Yes, that's what I meant (was I not clear?)

LPC1113FDB48/302 has two SPI's according to the data sheet, but only the SPI0 shows up in the peripherals view.
I'd like to see what SPI1 is up to.

I see that we now have a new version of LPCXpresso which still does not show SPI1 in peripheral view!
