Hello to all, Im still newbie here, I need help with PWM modulation on LPC2138. I want to riding stepper motor, I have a driver L6203, in one piece of this driver there are 2 transistors, so I need 2 this drivers to riding one motor. But I want to ride motor as unipolar, so I need 4 double edge controlled pwm chanels, but procesor allow only 3 double edged controlled chanels. When I use sing...

Hi Friends, I just stated on a new development using IAR 5.11 compiler and LPC2138 micro controller. And used the code provided by IAR ARM/examples/NXP/LPC213x code to get started.=20 Could anyone please advise me on the following issues, 1. I was wondering whether can I the use the same files provided under "ARM/examples/NXP/LPC213x/config" directory Flash.icf, Flash.mac, RAM.ifc &...

Hi Guys, I've made a board with a lpc2138 and a 20-pin jtag connector. I've used the schematic of olimex dev board ( http://www.olimex.com/dev/pdf/lpc-p2138.pdf ) as starting point. I've connected the TMS,TDI,TCK, TRST and TDO pins to the connector, I've connected all power pins to 3.3V or GND, I've connected a cristal between X1 and X2 with the capacitors to GND. There are also a ...

Hello , I have a small soft running on the LPC2138 using CAP0.0 input & timer0 -1. I'm using Timer1 as a free running Timer (Pclk = Timer1) 1:1 Clock on CAP0.0 input clock Timer0. Match Register (MR0) is set to 200. No need for interrupt. When Timer0 match MR0 , I stop Timer1 then read it. Purpose : Setting of UART on di

Hi, I use LPC2138 with CrossStudio 1.5. I have a problem when try to run my code compiled in release mode. When the code is compiled in debub mode works fine. In release mode occurs a "data abort". Why can occur this? Obviously there is a diference when the compiler optimize the code in release mode. How can identify where is the place that "data abort" occurs? I will try to fix that...

We have an application where we use the GPIO I/O pins on Port 1 of LPC2138 to an LCV244 buffer/driver. We found that randomly, some pins on the buffer driver were high or low at power-up with no program loaded to control the pins. We added 32k pull downs between the 2138 and the buffer/driver inputs to pull the lines low because the GPIO lines are floating inputs before program change

Hi, I would like to program the lpc2138 flash (on board) to a new firmware by using only the i2c. Can it be done? Should I use the IAR-EW ?intel-extended? output? If so, can anyone please tell me if there are any specific settings I should take care of, and which address should I start programming from? Thank you. ------------------------------------

Could someone tell me how to start to perform said operation? I would like to know which is the project that I need to start with for this conversion. I am guessing it is the one with LPC2368 / Eclipse more than the one with LPC2318 / Rowley. The board is a Xylo-LM, I would like to use both serials as console (I don't know at the moment which one I will use). TIA, Giuseppe ...

Hi. Perhaps this is not the right place to post this, so sorry if it is not. I am implementing FreeRTOS in my LPC2138 board. I am using the queue mechanism to serve the serial ports (this include an SPI port). In the ISRs I am using the xQueueSendFromISR() and xQueueReceiveFromISR () functions, to whom I pass the xTaskPreviouslyWoken parameter with

Hello, I would like to get a more or less precise time between two events (0 to some seconds with 1 or 10 ms resolution would be fine), but I have no timer left and the WDT is also in use. So I just could use the RTC of the LPC2138/48. Has anybody experiences using the RTC and CTCR to get a better resolution than a second ? I think it's a bit more work to manage the overflow of th...
