Is it possible to connect LPC Link (from LPCXpresso 1114 board) with EM773 development system?
It seems to me that I just have to connect swdio, swclk, reset and GND and everything should work.
I need it just for basic evaluation of EM773.
What is good solution for later development regarding programmer/debuger for EM773?
Thanks

It's possible :)

Should work :)

I think it's a good (simple & not expensive) solution :)

Since I don't own an EM773 (yet) :mad:, I don't know which MCU setting in LPCXpresso is needed (can't find a target like EM773 there).

But perhaps someone from NXP can inform us ?

The EM773 definately looks interesting, but how did that OL2381 slip past me? :eek: Looks awfully interesting, and reasonably priced. Nice to have 433 and 868MHz in the same transceiver, and they have some decent sample SW available for it with the LPC1343 (trivial to migrate to the 1114).

Sorry I can't offer much help on LPCXpresso. I'm sure the debugger is capable or working with the 773 ... it can't be that much effort to add since it's likely very similar to the 1114 (just guessing though).

I saw this thread and I believe this needs some clear clarification. Yes, it is possible to use LPC Link with an EM773, but there are currently restrictions.

1. From a JTAG perspective, either Red Suite or Xpresso can connect to an EM773. Very soon, I believe the EM773 configuration will be added to the supported part number list.

2. But the EM773 is not a general purpose MCU. To make use of the metrology engine inside, there is an SDK on the EM773 product page below. This SDK currently only supports IAR EWARM as the host IDE.

http://www.nxp.com/smartmetering

3. Inside the SDK, all of the software is open source for the EM773 plug meter and the LPC1343 USB dongle, except for the driver library for the metrology engine. So even if someone wanted to port this SDK to Red Suite or Xpresso, they would be successful in porting the wireless communication software and all the code for the LPC1343 USB dongle, but would be unable to port the metrology engine library in it's current form.

The good news is that I work for NXP and am responsible for the EM773 product as well. If there are enough users out there that would really prefer to use Xpresso or Red Suite as the IDE instead of IAR EWARM, I can work on getting the SDK properly ported, so that Xpresso and LPC Link could be used.

If anyone sees this support as a requirement for using the EM773, please respond to this thread and let me know.

I was working with the SDK this weekend, and put together a board that is pin compatible with the LPC1343 USB key. I was planning on sending out the PCBs this week, but the license terms are rather brutally clear for the SDK:

I found that a bit perplexing and extremely restrictive for a project that takes advantage of FreeRTOS, and open source project itself, and that basically means I'm going to have to write all of the source code myself from scratch if I want to use either the EM773 or OL2381 with any open source SW since this license is on most of the files, not just the metrology engine. You can't even use OSSW with this SDK without writen permission from NXP BV? :eek:

Personally, I think a GCC compatible version of the SDK is far more portable than IAR, though I haven't looked into it in enough detail to know how many IAR specific extensions are used. If the code was ported to GCC, it would definately be far easier to get it working in a number of other toolchains/IDEs based on GCC like LPCXpresso, Crossworks for ARM, etc.

The sample SW/SDK and proven schematics and board files make these two chips extremely attractive, but the current license terms basically render the SDK a non-starter for me since I often integrate different OS SW libraries, or if I'd like to use the OL2381 in something where the SW is open source using a commercial-friendly BSD license, etc., I have to write everything myself, at which point the investment in time becomes much more substantial.

KTownsend and all others,

First of all, thank you for bringing this issue regarding the current NXP EM773 SDK license agreement to my attention. I will make sure that this gets updated and corrected in a future SDK release. At this point, it is too late for SDK 1.2, as we are about the release SDK 1.2 to the web, but whatever release comes next will also include an updated license agreement.

Essentially, any and all restrictions are supposed to be limited to ONLY the metrology engine driver library within the SDK. This would be the library in the "LIB" directory of the SDK to be absolutely clear.

Any and all code outside of this "LIB" directory is free and encouraged to be used and modified by any user of the EM773, as it is meant to be an example to help users get started with the EM773. I can assure all users out there that we want you to use this code to develop your own applications for the EM773, LPC1343 and OL2381 products which are included in the EM773 plug meter development kit.

Only the metrology engine library itself is supposed to be tied to the EM773 and products incorporating the EM773 Energy Metering IC.

In the mean time, I apologize for what the current license agreement states. Please go ahead and use the above as your updated version until we can get it properly fixed. NXP does not want this to be a barrier to getting started with developing applications based on the EM773 or OL2381.

I hope this helps to clarify NXP's true intentions for the community, and please let me know if there are any additional questions.

Best regards,
Neal Frager

Neal,

I think a good interim solution is for NXP to update the license terms for the Metrology engine on the EM773 page of the NXP website. I believe you work for NXP, but any user could pose as an NXP authority. Recent posts suggest this site is already being spammed.

Regards,

Steve C.

Hi Steve,

Yes, we will definitely update the license agreement on our EM773 product page. But because this will take some time, I would like to verify my identity for the forum. I am the one giving the EM773 plug meter demo in the featured video of LPC Zone below.

I got a couple of the OL2381/1343 USB keys from this kit in the mail today, but what is the intended cable to hook something up to the connector for SWD/UART? I could just pull the SMT connector off and soldering some wirewrap on their to connect it to something, but if there's a part number for a cable I can insert I can probably just order a couple from Digikey or Mouser?

Update: This seems to be the appropriate cable? http://uk.farnell.com/molex/98267-0233/cable-flat-ffc-8way-152mm/dp/1079968?Ntt=1079968

LPC Xpresso Forum,

I am pleased to announce that we have released the EM773 SDK 1.2 to the web. Along with this release, we have also added a note below the release regarding the license agreement. The intention of the note is to be clear that we encourage all of our EM773 customers to use and modify the open source software that is part of the SDK. Please update with the latest SDK 1.2 below.

EM773 Product Page:
http://www.nxp.com/smartmetering

License Agreement Note:
"Please note that the metrology engine driver library included in the "LIB" directory of the SDK may not be modified. All other open source example code included in the SDK is free for users to modify and distribute with their own EM773 based products. Please carefully review the license agreement included with the EM773 SDK for details."

Best regards,
Neal Frager

In addition, we have created some debug kits for connecting SWD debug to the LPC1343 USB dongle. We are in the process of shipping these kits to our board store in Hong Kong, and they will have an OMxxxxx part number like all of our other development boards. Once these are released, we plan to put an application note explaining how to use them on our EM773 product page.

But in the mean time, if you are in a hurry, the connectors mentioned below should work.

I hope this helps!

The EM773 plug meter development kit with the US plug has part number OM13005 and is available from Arrow, Avnet or Future in the US. I am not sure why Mouser and Digikey have not purchased stock from NXP yet, but they are welcome to do so as well.

I hope this helps!

To be complete, the version with the EU plug has part number OM13006. The two kits are actually identical except for the physical plug, as they both support 90-270 and 50/60 Hz. In Europe, the kits are also available through the same distributors, Arrow, Avnet (both EBV and Silica) and Future.

Being interested in the EM773 I have some questions I hope someone can help to answer:

1) Will the SDK be ported to LPCXpresso IDE from Code Red? If so, when? The Code Red support team wrote to me that they have no immediate plans to support the EM773 and if I would like it to be supported I should contact NXP. Well I would like that :)

2) If using IAR what debug probes are supported? Looking at the schematics I see only a 10-pin connector. Will e.g. IAR J-link lite for ARM work?

3) The plugmeter includes a relay that takes up a lot of space. Can someone explain to me what it is used for? Browsing through the code it seems to be used in some calibration rutine. But can one do without?

Hello Martin,

Here are some answers to your questions about the EM773.

1. Right now, we are waiting on Code Red Xpresso version 4 which will be EABI compliant. This will allow for rebuilding the IAR based SDK without needing to modify the actual metrology engine driver library. Once version 4 is released from Code Red, you are welcome to try porting the SDK over to Xpresso. At the moment, an official NXP porting effort has not yet been commissioned.

2. Yes, J-Link lite and any other JTAG emulator that works with IAR EWARM will work with our EM773 plug meter development kit.

3. The plug meter has a bi-directional radio included with the OL2381 and a bi-directional wireless M-Bus T2 mode software stack running on the EM773 CPU. This enables the PC software to send messages back to the plug meters. The point of the relay is to enable remotely turning on or off the power to whatever is plugged into the plug meter. This relay can be removed entirely, if not needed, as it is an optional function for the EM773. Other options include replacing the relay with a dimmer, as the EM773 could potentially support dimming of lighting solutions as well.

I hope this helps, and please let us know if you have additional questions.

Neal Frager
