I do have a generic question about the SSP/SPI in the LPC2478. The user manual confuses me a bit.!!
SSP0/SPI can be used either as SSP and SPI. But the SSP can also run...

I have a Maxim thermocouple converter (MAX6675) hooked up to a
LPC2294's SPI. The MAX6675 is SPI read only device, i.e., enable
chip select and it ...

This is not really a LPC question, but didn't know where to post it.
Many here are using SPI and I was wondering if anyone has had any
issues with standard protocol with SPI per...

I'm connection my 2106 with a device that uses a 9bit interface. How
can I use the hardware SPI with this device? I can do a software
Master SPI, but will be slow.

Hi at All
What is the difference from SPI and SSPI interface?
I can send at receive the data a max speed in SSPI?
What is the max speed in SSPI interface?
In this my applicatio...

Consider a LPC2124 in Slave mode.
What is the effect of pulling the /SSEL line high (called DATA ABORT)
during an SPI transmission.
What is the effect on the SPI ...

Has anybody done any framework for FreeRTOS with SPI support before?
I'd like to process interrupts from the slave devices as soon as possible.
It seems implementing semaphores ...

I am using the LPC2138 as SPI Host controller & CSR Unifi Chip as SDIO
card(in SPI Mode).
I need to connect the Unifi Chip(SPI Mode) with the LPC.
I am able to initili...

Do any of the LPC ARM's have faster SPI ports (like maybe with a FIFO),
or are they all basically the same as LPC210X?
I thought I saw mention here that one of t...

Having a strange problem with SPI on the LPC2468. There are 2 sets of
pins which can be used for the SPI, but we can only get one of the sets
If we configure the SPI ...

You can use a GPIO as chip select. In fact it's common with SPI to
use many GPIOs on the host if you have many SPI slaves. This
chip select for SPI is not the equivalent of chip ...

I use SPI interface with lpc2106.
I have setup the SPI and load the dataregister. After that I can see
SPSR is 0x80 and SPINT is 0x01. It ok. But when the whi...

Both the SPI interfaces of LPC23xx are used up in my design. Is it possible to use SD/MMC interface to connect simple SPI Flash ?
Boris Kralik - Jun 24 2008
We have a discussion about number of bits of SPI, which I want to
transfer/receive. My opinion is, that SPI on LPC2294 is only 8bits,
SPI Data Register is only 7:0 b...

What is the difference between SPI and SSP? They share the same pins
and seems that SSP can do all the SPI can, while being 4 times faster.
Am I wrong?
FIRAT KOCAK - Apr 1 2009

chip select input but for i2c devices there is not any kind of input (
some have reset pin, this pin...
