Does anyone know the register locations for the 2nd I2C interface (I2C1) on the LPC2103? Philips says "use the LPC2106 data until the LPC2103 data is available," but the LPC2106 only has one I2C, so the 2nd I2C registers are not defined in the LPC210x.h header file.

Hello, Downloading to boards such as Keil's MCB2103 via the Philips flash utility requires an RS232 port. However, most new laptops don't have one these days. In a post a while ago I read that one of the forum members (Varuzhan) did this but it wasn't with the newer LPC2103. So, is it likely that any USB-RS232 adapter could work or do I have t

I'm a little confused at what speeds can SD/MMC cards be accessed using SPI on the LPC2103. Normal SD/MMC cards support max 25MHz for SD and 20MHz for MMC. If my LPC2103 is clocked at 70MHz, APB divider set to 1, then it looks like the maximum speed I can get out of SPI0 is by setting the S0SPCCR SPI clock counter register to it's minimum value of 8. 70MHz
