Stand alone programmer?

[Ronnym]

Other than the nRFnGo setup, is there a stand alone programmer for use with the LE1 and SDCC?
Thanks,
Ron

Hi Ron

I am currently working on a programmer for the nRF24LE1 by using a Signalyzer from Xverve;
http://www.xverve.com/products/development-tools/signalyzer-tool-dt-usb-st.html

It's pretty straight forward to use the programmer, and you can program directly from the application by pushing a button or externally by a falling edge on one of the GPIOs of the Signalyzer Tool. (The GPIO has an internal pull up, so only a simple button to GND is needed to start programming.)

One programming cycle takes about 1.6sec when programming 16k of Flash. Less if the hex file is smaller.

Note that the programmer doesn't work on the engineering samples of the nRF24LE1 (marked with 'AX' on the chip itself).

This is the first release, and I guess there might be some bugs, but I will fix those as people start reporting back on it. I might release the source code in the future, however I would like some feedback first.

/Kenneth

edit: release v1.01
bugfix: last byte of the hex file was missing.
bugfix: fixed documentation (was an error in the figure).

Has anyone tried the ISP-3 programmer from E-Labs? It now supports the 24LE1 and 24LU1.

Hi, kenneth

Could u give me a copy of infopage of nRF24LE1(32pins), becouase my nRF24LE1's infopage has lost.

Thx

Hi Kenneth,

I have been playing with DECIBIT modules (nRF24L01 + atmega168) for some time, but noticed the Nordic nRF24LE1, and i want to try this all-in-one chip. Unfortunately the development kit is very expensive and therefore i want to use an alternative solution. Most of it i found except a simple programmer. I downloaded your code but of course it will not work with the decibit SPI programmer i have. The DECIBIT programmer is a straight forward FTDI solution with a FT232R chip. Not so much different than the Signalyzer would be my guess, and may be your programcode can be adapted to work with my programmer or any other FT232R cable. Is it possible to get more information on this, or even the source of your program? If not will your code work with the less expensive Signalyzer Lite?

Thanks in advance if you could answer me.

I have not done any development on this project since the initial post, so I release the source code in case it can be of any use. I have not tried it with the Signalyzer Lite.

Thanks Kenneth,

Great stuff. The nRF24LE01 breakout i have from DIYembedded has a serial bootloader programmed, but the tiny RFdigital.com units have not, and i will try them later with your software. By the way i saw that the Signalyzer uses the FT2232 instead of FT232, and the 2 are not compatible if the build in hardware SPI is used on the FT2232. The signalyzer Lite uses the same FT2232 i think so should work with your software.
