thank for attension on my problem at LPC2000 yahoogroup! i'm using LPC2214 to collect data form ADC chanel control and store it in the ARRAY data by timer interrupt match each 1ms.That means I samples sample per 1 milisecons.And after 50milisecond I genearate all 50 collected data in ARRAY to PC through UART port.but I have problem that is "Non-aligned Access: Thumb Instruction at 000006

Hello, I have an LPC2148 board that comes preloaded with a USB bootloader. The bootloader checks if a binary file is located on a uSD card, and if the file exists, it burns its content to flash. If no file exists, the bootloader invokes the user application at address 0x10000 in flash. For those familiar with it, this is the SFE USB bootloader. This bootloader works great and I have been a...


LPC200 RTC Design for Accurate time

The 32.768kHz RTC is typically a tuning fork type. The Xtals are typically characterized with load capacitances of 12pF and 6pF. Experience when tinkering with Philips I2C RTCs and other RTC manufacturers , tells me that the 6pF load capacitance types seem to be more accurate (stable) with these values. What determines this? QUESTIONS Q1 Is the LPC2000 RTC Osc characteristic, Cinput...

Hi guys, Does anyone know if it is possible to achieve 115200 bps using the 'LPC2000 Flash Utility' with LPC2138 and XTAL=10MHz ? The maximum baudrate I'm able to use is 38400. Even 57600 bps is not working. I made a routine to test UART0 @ 115200bps and I can only use this baudrate properly when I adjust the fractional divider register (U0FDR - LPC213x/01 devices only) to get the minimum...

System is LPC2292; XTAL = 14.7456 MHz; PLL disabled; MAM disabled; VPBDIV = 1; UART = 8-data, 1-stop, no-parity, FIFO enabled. Symptom are that for certain (low) baud rates, UART silently drops characters on Rx channel when saturated. There is no indication of this in the LSR and none of the error bits (OE|PE|FE|BI|RXFE) are set when this happens. It appears that UART logic is failing t...
