Hallo
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...

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?

Greetings:
I find the LPC2138 User Guide rather vague for the SPI, SSP
peripherals. I wonder if there is additional support information for
these peripherals that I d...

Hi. I'm looking for a SSP uClinux driver.
Can anybody who used/wrote this kind of driver help me with a good link or even with a source code :)
I know that in some starter kit...

SSP is a generic term meaning synchronous serial port, much like
SPI is a synchronous serial port, although SPI was originally made
by motorola. Most processors that state they ...

Hai,
Is anybody having LPC2148 SSP (SPI1) slave mode example code.
I am trying to establish communication between two LPC device. One act as SSP (SPI1) master and another ac...

Hello,
My SSP controller is configured to use the GPDMA of a LPC2478 to deliver data to external RAM. The SSP's hardware buffer is 8 bytes (fixed), and the DMA's transfer size i...

Hello all users!
Has anyone used the SSP DMA on LPC32XX?
I compiled a SSP sample project from IAR Compiler. It sends 256 bytes DMA channel0.
If I change the DMA_SIZE from 256 ...

Hi all,
In theory, max baudrate for the SSC will be CCLK/2/VPBDIV.
So it seems possible to clock the SSP @30MHz.
Is it the case in real life?
Thanks in advance

Hi,
I can't succeed in using my SSP in SPI mode at speed more than 10MBit/s
I use the loopback mode but I assume this is the same in standard mode...

Good afternoon, everyone,
I have an LPC2103 set up to receive data as an SSP slave. I am running at a

I use SSP on LPC2148 to drive the audio codec.
It works fine with TX FIFO at least half empty interrupt.
Means initializes OK and runs well if untouched.
However, when I tried t...

Am I right when I say SSP can be set to divide by 2 or 4 but not 3?
I am trying to find the best clock for MMC (20Mhz) but with 60Mhz clock

I'm interested in pushing the SPI. Mainly, I'm interested if the max SCLK-PCLK ratio of 2 still applies when the SSP is a slave. Seems you usually have to drop the rate way down...
