Hi all, I'm trying to test the ADC on the LPC2138 (using Rowley and Olimex evaluation board), but I can't get it to work and I can't figure it out. The ADC conversion never completes and my code just blocks while waiting for the done bit to be set... Here's my code: //init //#define AD0CR (*((volatile unsigned long *) 0xE0034000)) //#define AD0DR (*((volatile u...

I don't understand the idea of VBAT in LPC2138. I want to have RTC running in case of main power supply failure. I didn't find any information about a battery backup switch in LPC. So if I connect a battery to VBAT, RTC is powered from the battery all the time. I'm afraid that the life of my battery will not be long. I can add an ex

Hi all, I am going to try again to port the freertos for this combination: - LPC2138 with just one uart (uart1) readily available (there is a fpga between uart1 and the serial port configured to forward data to the pc). Uart 0 pins are available and can be connected to the fpga as well but not both at the same time. - 24MHz fixed clock (slave from a FX2 chip), I would like to reach 48MH...

Hi, I am a hardware engineer and just started to pickup the firmware development on RTOS. I find that the FreeRTOS could be useful for my remote network project. I am a beginer in using FreeRTOS and LPC2138 processor. It seems that for LPC series, there are only IAR, GCC, ROWLEY and KEIL available on the web. Does anyone here tried FreeRTOS in ADS 1.2 ? I am using the Codewarrior IDE w...

I have a board containing an LPC2138. I cannot get the chip to come out of bootloader mode or at least that is what I think is happening. I can load programs with no errors through a Keil ULINK but when I go into debug, the code I see starting at address 0 is not my code but instead is a mirror of the bootloader. I can also use the LPC2000 Flash Utility to load the chip, examine the buf...

I built a new board and put on the RTS controlled Reset feature so I could allow the Philips Flash programming utility to control DTR and RTS to program the LPC2138. A problem happens with I bring up TeraTerm on the same serial port. TeraTerm sets the RTS line, which holds the LPC2138 in reset. Did I miss an applications note somewhere?

Hi, I newly started working on this board. I am trying to flash a hex file onto my lpc2138 board. But even though I flash different hex files, I get the same output on the board. i.e. I see that the 2 LEDs glow on and off alternately. I am now confused whether my board has a problem or I am flashing incorrectly. I also suspect the Erase of the blocks is not happening properly. I am using Flash ...

Hi, sorry I know the Title sounds like a really trivial problem, but I tried everything I could find on the net, and now I'm a little clueless. A while ago I designed a little board with a LPC2138FBD64/01; The schematic was based upon an olimex dev board with LPC2138 (http://www.olimex.com/dev/pdf/ARM/LPC/LPC-MT-2138%20-%20schematic.pdf). I managed to establish a JTAG-connection using the ...
