That is a very good, well documented article Jan.
Thank you

Would it be possible (if people would find it useful?) to expand this article to cover other masking, Checking and toggling bits and bytes.

Dear All,
After a long time of work, the software has been improved tremendously. The result is a much more stable working of this speed control even under many kind of noises.
The flowcode, the electronic design and the printed circuit board are today published in the ELEKTOR magazine 7-2014
Nederlands:
• RC-snelheidsregeling voor gelijkstroommotoren
Klein en veelzijdig

English:
• RC Speed Control for DC Motors

Probably later on also in Spanish

Please find an update of the RC speed control of DC motors.
After some practice in my garden gauge I train (45 mm) I found that the Flowcode is working correctly, but the speed control bridge used ADP3624 will start oscillating at higher currents. I tried a lot to improve it, but without success.
That made me to look for a better one, which I find here in Matrix house with the EB094 block. Here is used the L6206 bridge, which even have 2 outputs for 2 DC motors. The only thing I did is to produce a small PCB board which combines both the microchip and the bridge. I extended the board with a LCD connector (2x5 pins) which can easily be connected to the Matrix LCD board by means of flatcable connectors. Additional is the V+ (5Volt) power available in the connector.
In the meanwhile the Flowcode has been improved and extended with the LCD output. The LCD output will be used only for test reasons, because it delays the response to RC-time changes.
Please find the last Flowcode, the electric scheme and the PCB layout. The PCB format is 32x50 mm. Even as amateur it is possible to solder the SMD parts. Still interested? Contact me and I can be delivered the PCB board for low cost .
Kind regards

Well done Jan, what a super project
The L6206 bridge has gone into our new MIAC range too

Thus, there are three general methods of speed control of D.C. Motors.
Resistance variation in the armature circuit: This method is called armature resistance control or Rheostat control.
Variation of field flux Ф This method is called field flux control.
Variation of the applied voltage.
