Hello, actually I'm working with the LPC2132 uC and with the development software uvision3 from Keil. I'd like to protect my source code by enabling the code read protection. Through the datasheet I know that I have to write the constant 0x87654321 to adress 0x1FC. When I look into the Flash after programming the uC(Code read protection isn't enabled yet) I can see that at the adress ...

Hi, First unit to be repaired of a new design has been sent to me. As It's the first one, I'm more interesting in identifying what happened than in repairing it, in order to know if it's necessary to change something in HW or SW for future supplies or if it's ok as it is and it's just a common reparation. LPC2132 in the not working board is not starting up. If I debug using JTAG I can see th...

I've got a LiIon barrery design with an LPC2132, and when I put it into power down the supply current stays up around 700uA. That seems way too high. I am running it on 3.3V and I have switched basically all of the pins to Input so that non are driving pull up/dn resistors during powerdown. I even shut off the JTAG and UART so there was no current being put out to anywhere else. I ...

I need LPC2132 to run @32MHz for 2mSec (my time measurement periode) and then drop speed to 4MHz for 100mSec. This cycle continues forever. Is it possible to change MSEL while running? I am afraid of Capture range, Locking range and stabilizing period etc. Anybody experianced with this? Vimal Amin

Hi there Im making a system where I'm using all the above mentioned interrupts. I have had the TC0, PWM and the ADC running nicely until now, but when I add the UART0 the TC0 goes dead (it's running a 1 Khz clock) I want the UART0 to give me interrupts when it receives a byte and only when that occours. When I send data I don't want to receive any

Hi I have a board with LPC2132 MCU . ISP Version 2.2.2. works fine at all speeds . When I switch on the same board to LPC2138 ( same crystal 14.7456MHz , same board ) I am having download file problems . Switching back and to LPC2132 works fine . After putting LPC2138 ( different piece of chip ) on again it has similar download problems ( even at slow speed li

I followed the example from the Insiders guide from Hitex, but it seems if it is designed only for the Keil ARM compiler. Also I suspect it to have an error where ADCR should be ADDR. Anyway the interrupt function doesn't get called, and I have no clue why not. In the Keil example they make a change in the startup.s, but doing that didn't solve the problem

Hello, I have problems on my board trying to use two capture pins on the same timer. My purpose is to use CAP0.2 (PIN0.28) and CAP0.3 (PIN0.29) on Timer0 in order to generate two interrupt. CAP0.2 is set to generate an interrupt on a Rising Edge and CAP0.3 on a falling edge. The problem is that if I use only CAP0.3 I have the Interrupt serviced and handled correctly, If I add also CAP0.2, ...

Hi, I'm working with an LPC2131 in the Keil compiler. I've made two projects, a bootloader project and a main application. I want to make use of a shared variables to have the two apps communicate with each other. I'm able to create a variable on a fixed address using the following code: TE_SHARED shared __attribute__((section(".ARM.__at_0x40000000"))); So both applications read an...

Hi, Can anyone tell me how to write an UART RX ISR in order to receive several kinds of packets with different length? The kernel is FreeRTOS. I have excerpted one piece of sample code snippet from one of the FreeRTOS demo port for LPC2129, as bellow.

Hi fellow forum-goers, I'm trying to add a general-purpose CAN to UART function to an LPC2129 setup. CAN1 works at 250 and 500kbps, so I modified my code to add CAN2 but am experiencing difficulty. I'm hoping one of you gurus is willing to look over my configuration. CAN2 is supposed to be "scalable" to any of several baud rates, but I am testing on 33.3kbps on a SINGLE WIRE networ

I can't quite believe i'm having this problem! i'm a professional software/hardware developer but not in the GCC/Arm world. I'm a real newbie in GCC but have C experience on other platforms. I'm so stuck...but I suspect it must be something very simple. I have a very basic GCC program that can't access any of the standard functions. I'm targeting a philips LPC2129 ARM7 processor.

I have appnote 11008 open right now and this seems like overkill for what I want (and I'm confused as to how I would extend for char arrays). I have a board that reads a configuration file from an SD memory card. Sometimes, that card is unreadable and a value is needed regardless. The boards are tuned for different devices, so a single default will not work. Since I have tons of flash memory...

Hello Group, I am using a development board with LPC2129. I downloaded the sample code i.e BlinkyCAN which came along with Kiel and Jlink package. The sample code is able to send and receive the CAN messages. However, if I put the breakpoint in Receive interrupt, the break point is never hit. May I know the reason? Can I any give me a sample code which has got simple CAN receive interrupt ...
