Darn It, Post Comments – Don’t send me email unless you must.
Comments are the fuel the keeps me busy! No comments – no new work.
Hello Jim, How can I contact you in order to purchase some of your LED boards? Thanks Dan
Dan,
My email address is Jim dot Kemp at Ph-Elec dot com.
Which LED boards are you referring to? I’ve got both HBLED adapter boards and Kemper LED boards. I’ve got a few extra of both types I can send you. The Kemper LED boards are easy to build if you can handle surface mount components. The smallest part are the 0805 resistors. The HBLED adapter boards really need to be reflowed. I’ve had real good success using solder paste and a hot skillet. Reflowing allows a whole bunch to be soldered at once. However, you might be able to solder a few by hand if you know how. The HBLEDs are the problem – the solder pads are under the LED chip.
Anyway, I don’t really sell things anymore. It just was not worth my time to fill small orders. Still, I’ll send you a few boards of either if your interested.
Just let me know,
Jim
Hello Jim,
thanks for your FreeRTOS work. It saved me some serious time.Anyway I don´t get to what pins you connected the Nokia 5110 (I´m missing SDIN and SCLK). I have to omit I just started with your FreeRTOS port.
Thanks
Gregor
Gregor,
Thanks for the nice comment. I’m glad the source code is working for you. Someone else warned me I had posted some code that had a bug in it. On my to-do list was to verify the source code I posted worked right out of the box. So please, let me know if you have any trouble.
Give me an hour, or two, and I’ll sort out the LCD pinout and add the info to the web posting. I’ll send you an email when it’s done.
Thanks again,
Jim
Gregor,
Below are the pinouts I used on the Discovery board.
Hope this helps,
Jim
