I'm looking for compile ucos-ii RTOS port to the Philips LPC2129 with the GNU Compiler. The code available on www.micrium.com site is, instead, intended to be used with the IAR Compiler. First of all, I need to translate the assembly code for IAR Compiler to the GNU Compiler syntax (GAS, if I am not wrong), and I'm searching for a IAR Assembly User Guide but without success. Am I not able or...

Howdy : I have a Philips LPC2292 ARM7 and am connecting it to a Spansion Mirrorbit FLASH device with fast page mode. I was wondering if the page mode capability of the FLASH was in any way compatible with the BurstROM mode of the EBC in the ARM I can find no details about the BurstROM mode anywhere. What constitutes a burst ? Is it similar to page access in the FLASH (i.e. the bottom N ...

I'm looking for a mid-capacity static RAM part that I can use with a TI MSP430 series MCU using a few interface lines and serial transfers. I am finding a few serial-interface static RAMs (such as the Philips part) but those I'm finding are very small capacity for my application - 256 bytes or less. I need something in the 2 to 8K byte range, but static RAMs in that range are parallel (addres...
