Has anybody implemented NAND flash driver on LPC210x ? Now we are considering using LPC2106 in our project which needs a NAND flash to storage data. Two UARTs, I2C and SPI are all used for other functions. If p0.23 to p0.31 is used for NAND flash data pins, it wi

Hi everyone, I wanted to fabricate a board with the LPC210x that will have USB connectivity. I have found some simple chips that would definitely do the job - for example PDIUSBD12 which is a USB interface device with parallel bus. However, I don't think I would be able to bootstrap

Okay, I'm trying to find out a way to program 13 different LPC2000 devices on the same jtag chain. We have one LPC2138, and twelve LPC2103's. We're currently using the ARM-USB-OCDs with Rowley CrossWorks and Vista (meh). We can source an XP machine with a parallel port if this is what it takes. We'd prefer a windows based solution as that is what the techs have access to already. I a...

I finally have one of Leon's lpc210x proto boards assembled. The problem is the MAX3232 runs warm and seems to be drawing 150mA or so--it varies a bit. The lpc2106 runs at ambient and has detectable 10MHz on its clock pins. Removing the MAX3232 from the board causes it

Can someone tell me if it is possible to program the lpc210x with the philips isp program if the chip is used with a RS485. The rs485 hardware forces the pc software to receive the data it sends. Maybe this may conflict with the behaviour of the isp software. Has someone done this before ? Johan

A long time ago Amontec gave me one of their Chameleon units to try with my LPC210x board. I couldn't get it to work. I thought I'd try it again with the latest software, but still can't get it to work in either Wiggler or Raven mode, even at very low speeds. A genuine Wiggler works fine, of course. Has anyone got the Chameleon to work with the Philips ARM chips?

Testing FreeRTOS on LPC2106 with both UART channels outputting at 115K baud. I'm using the transmit FIFOs, so the interrupt rate is 1/16th what it would be without FIFOs (I'm amazed at how rarely I see sample code using the FIFO or using it such that it cannot do its purpose). The issue and question is: I'm using the FreeRTOS message queue to service the transmit UARTs. With message queues o...
