Hi Vasile,
In my time a birth was still followed by a placenta, nowadays an iphone comes after.
A long time ago I was infected by Wouter, Jal is even more persistent than corona, see http://www.voti.nl/setalk/n_index.html
regards Hans

Hi all,
I tried the MT8870 a few years ago. I need to send data packets of 4 bytes, a start byte, a device byte and a high and low nibble. I used tone 15 as start byte, the second tone as device byte (0-15) 15 then two tones for the nibbles. That worked well but a DTMF tone should be 40 ms with a 20 ms delay.!!!!!
If I compare that with the baud rate of MIDI (31250) which I use so far, then DTMF is much too slow.
I then tried the TCM3105. Worked well but they are no longer made. A handful I've had from China were all broken.
So… I'll keep controlling my puppets on MIDI for the time being and if spoken text is needed I'll control the MP3 player
. I still hope one of you comes up with something different.
Rregards
Hans

Hello everyone,
My grandfather Hans has only one usable eye and has got an infection on it. We have read your contributions and he is very happy with them. Sorry but he can't work with it right now.
Regards Marieke
Hi Kiste,
Sometimes I have to push things aside. So is this topic. I have taken up the matter again and on my pin board both the transmitter and the receiver work with a 12F683 at 1200 baud. I did put a 100nF in series at the output according to your diagram. I also put a similar filter in the input of the receiver. Identical to your proposal but because I know absolutely nothing about filter matters I don't know if I did this right.
I feed a separate uart signal as input and read out another uart with the receiver.
I recorded the signal with audicity and saved it as WAV. When playing back to the receiver I do get responses but there is quite a bit of junk.
My question : what should the inlet filter to the receiver look like.
I know your box of thanks is already full, but I'll add another one.
regards
Hans
Hello highly honored public,
I did some research in low/high pass filter science and found a lot of calculation programs.
In the contribution of Kiste 20 Mar. 2022 13:22:10 an R value of 680 .. 1 K is indicated and a C value of 1uF. The system works with 5 and 8 kHz. When I run the found calculation tool on it, I get very different values. I must be completely wrong again, but the transmitter and receiver do work, only with glitches.
My question is outside the JALLIB world but I'll try anyway.
regards
Hans
