I'm trying to build a control platform using a LPC2138 processor. Is there any open source TCP/IP stack and RTOS available which can be used? I came across FreeRTOS, which seems interesting. Does anyone have any experiences with this? Is it a decent OS? Thanks for all possible info.

I recently switched development boards from the Olimex LPC2138 to the LPC2148. Now it seems that the standard Philips Flash Utility (ver. 2.2.0) that I was using for the LPC2138 does not include the LPC2148 in its supported devices list. What are you using to program the flash on the LPC2148? Is Lpc21isp the only free Win tool for flash programming on the LPC2148? Thanks, Paul

Hi guys, I searched the messages and I couldn't find a final answer concerning this issue. Is it possible to use the watchdog as a periodic timer or not ? According LPC2138 user manual it is not possible: "WDINT: The Watchdog Interrupt Flag is set when the watchdog times out. This flag is cleared when any reset occurs. Once the watchdog interrupt is serviced, it can be disabled in ...

Hi all, I'm trying to get started on a custom board using an LPC2138. To jump start things, I got an eval of the Rowley Cross Studio for ARM, and installed the LPC2000 CPU support package. I can compile programs using Cross Studio, and download them using lpc21isp. Problem is, nothing happens. To start out, I just took a blinky example that goes with a Keil eval board. It's simpl...

Hi all,I got a problem if some one could help pls.I got a project created by one company (although one guy works there), it is in crossworks IDE and lpc2138 processor. The hex file that is created by their system is 156 kb size. But when I build the same project (release configuration), the file is 177 kb size. Also the wake up (blink red led twice with a difference of 200 ms) signals this files g...

Hi, Please help with the Adcs. I having problem of reading conversion from ADC_1. LPC2134/6/8 have two ADCs and 16 pins to connect to. I wrote the following code. and it runs fine in the evaluation board LPC2138, but not the target board LPC2134. Here is what I did.

i am trying to use LPC2138 to control LTC1451 (DAC) by SPI protocol. I use Keil MDK-ARM uvision4. LTC1451: 12 bit, CPHA=0, CPOL=0; When CS is low the CLK signal is enable, so the data can be locked in. When CS is pulled high, data is loaded from the shift register into the DAC register. Load MSB first. My code is as the following. However, when I simulated with Proteus, it is not as the valu...

Hi, I need someone to be mercy and send me a compiled gcc example of a program to send test chars on uart0 and uar1 for a LPC2138@24MHz. I cannot think anything wrong with what I do and that basically works for uart1. Uart0 is connected thru an FPGA, Uart1 is directly connected to a serial port. The fpga is programmed to just forward the signals between the LPC2138 and a serial port. O...

Has anyone ever experienced a similar problem with timers on the LPC2138? I want to get a timer to generate an interrupt at every 1ms (system tick). I configured the prescaler so the timer would count with a 1ms period, and the match register set so the timer would generate an interrupt every 1ms. This resulted in a 2ms system tick ??!! As a test, I changed my prescaler, so the c...
