Farnell has the LPC812 LPCXpresso board in stock: http://uk.farnell.com/nxp/om13053/eval-lpcxpresso-lpc812-cortex-m0/dp/2254492?Ntt=2254492 It was only available from Mouser, previously. The shipping cost made it rather expensive outside the USA. Leon -- Leon Heller G1HSM ------------------------------------

Evening all, I've been working on getting my I2C communication from an LPC2148 to an MCP32017 I/O expander and I'm running into some issues. I'm pretty confident that I've got the state machine down and that I am moving through the transactions correctly, but I cannot for the life of me get the 32017 to light up an LED. I try transmitting according to the user manual for the LPC2148 and the dat...

Hello, just want to point you to a nice new feature in Cortex-M0+ (like LPC812): Micro Trace Buffer (MTB) MTB is a trace mechanism. Once enabled it collects addresses e.g. of jumps in a configured area in SRAM. (ring buffer) It can be enabled/disabled via software (or SWD i think) and can be read out afterwards. Example use case: Trace execution of your code and dump latest ex...

Hello, I'm new to this group, I hope I will be useful also in this community me too, but now I need your help, I have a project on a map LPC2148 Education Board and I have put in FreeRTOS, j 'I found a source here in the file section but I did not fully comprehend how it works? and I want to create my own tasks and add them to FreeRTOS but I have not found how I work with a students licensed Cross...

Hello, i am currently trying to get the LPC812 to use its deep power down mode and wake up via WKT. Here is what i am doing: I start up the chip. UART is working. LEDs are working. When a certain key is pressed, i prepare deep power down mode (see code 1 below before WFI) and enter deep power down mode via WFI for around 10 seconds. After around 10 seconds the chip wakes up a...

Hi All, the SPI code is working fine with keil simulator it is going to ISR whenever SPIF is set. but when the same code is loaded to LPC 2294 hardware board it is not working and indefinitely waiting for SPIF bit. In the above case, whenever data is written to S0SPDR interrupt is getting generated (observed on Vector Interrupt Controller) but it is not entering in to ISR and waiting continuou...

Hi guys I was working on LPC11E14 when I realised that there are no Eagle CAD files available for LPC11E14. I wrote to NXP and they told me that they do not have the CAD files for the same. I do not understand why would they produce a component and not provide its CAD files, given that is one of the critical support work to be done with the device. Does anybody have any 3rd party CAD ...

Hi Guys I have a quick question. I was having LPC1114FBD48(48 pin) lpcxpresso development board which I used for development. Suppose now I want to switch to LPC11A14FHN33(33 pin) (or any other LPC11x14 variant, where x = A,C,U,E etc) in my final design. Can I use the driver files and examples programmes of LPC1114 for LPC11A14 ? As I go through there are a lot of example projects for LP...

I am using the WDT with our security system. Since you can not turn off the WDT once started until it expires, I have two instances where that it is an issue. #2 more so than #1. 1. When I turn the unit off (keyswitch), I go to Power Down mode where a software reset (caused by a Key ON) is the only source of a wakeup. I noticed that the WDT is not disabled, but does not cause a wake...
