Hi All, We have a product which has been in production for some time using the LPC2129. The newer units now have the LPC2129/01 (as nxp has made the earlier revisions obsolote). However, in NXP's wisdom they have changed the CAN channel filtering indexing from 1 & 2 to 0 & 1 !! Which ind of screws up our code somewhat !!! Grrrrr ! Now, as our current firmware needs to support existin...

I am trying to understand how to manage IO with interrupts when using CrossWorks Tasking Library (CTL). I have a small program with 3 tasks. Two tasks just blink LEDs and the third outputs via UART0 using interrupts.

mornin' all.. A design change has left me with a requirement to use an SD card with the SPI interface on my LPC2129. This interface has no FIFO buffer and a high transfer rate, (well, can be, anyway). To implement the interface, I need to read/write 512-byte sectors. I have a couple of problems. All my comms IRQ interrupts have no nesting. I have only one buffer supply queue into all...
