Let’s arrange the words so that the words can be recognized by just decoding the lest significant digit number on the digital display. I have been searching it, one of hm22007 in malaysia Troper electronicbut troper not available, troper had sold out and no IC stock at this moment.! I’ll give you all I have on this one.

Sceadwian Banned Mar 24, The effective vocabulary drops from forty words to ten words. To display the command numbers 2 common cathode 7 segment displays are provided.


Begin construction by soldering the IC sockets on to the PC boards.

Thank u Max and hotwaterwizard ix friends and thank u for ur help and i’m glad there r people who care. It is not necessary to train all word spaces. The decoding circuit that recognizes the word number and performs a function must be designed to recognize error codes 55, 66 and 77 and not confuse them with word spaces 5, 6 and 7.


Let us test the board by connecting to a Motor through a motor ix board L To accomplish this word spaces 01, 11, 21 and 31 are allocated to the first target word. We continue in this manner until all the words are programmed.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Hero Banned Mar 24, The more system resources that are allocated for independent recognition the more robust the circuit will become.

This can then be later connected to a microcontroller hk2007 further functions. Mb u shd try t rst of ur kybd. This demo hm200 allows you to experiment with dependent as well as independent systems. If the system has to work under noisy environments, background noise may corrupt the original data and leads to malfunctioning.

May 16, at Here are more files. This kc enable the system to recognize different voices, inflections and enunciations of the target word.
