Re: Schematic of Front Panel_Matrix Ver V012

 

The schematic like below may be tried, but I doubt it is necessary, as the original I2c Matrix circuit and the software are working effectively with out bugs, I think no need to experiment further and land in trouble.
I am putting the below schematic for discussion purpose only. Any one want it to be evaluated, I feel it is interesting.

And we would all encourage you to experiment¡­ set up that 8x8 matrix¡­ write the code to support it¡­ and put 64 switches on your front panel if that suits your needs.? The hardware is all there to support your addition.

The reason is because I didn't want to suck up 18 I/O pins when I originally designed the T41 switch matrix. My idea was to use a single analog pin and free up 17 other pins for other uses. The addition of the MCP23017 chip came after our original design. Indeed, a major goal of the T41 was to encourage experimentation and the addition of I2C expander chip was done in that spirit.

Yes, That can be done¡­ but do you have or want 64 switches to so ¡°something¡±???? If so, I would encourage you to set up the 8x8 matrix.? Of course, that doesn¡¯t work very well for the encoders.? Also¡­ remember you have a TFT display that may or may not have a ¡°touch screen¡±¡­

Re: Schas to be hematic of Front Panel_Matrix Ver V012

 

Yes, It is possible but not needed for us, If key matrix is used, the existed software has to be changed. Go on changing the working software may lead to further troubles.?

Nice bezel on the display.?

Re: XMIT Calibration

 

This is a seat of the pants checkout- plug a set of earbuds into the QSE jack (exciter) and while running the test, pull off L and then R. The channel should drop.?

Then if you have a scope, probe the QSE outputs from the op amps to the FST3253, should see the same behavior if you disable one or the other.?

This looks like L and R are shorted together or one is missing.?

Re: XMIT Calibration

 

V049 should work.? V049.1 has only minor changes to the calibration graphics.
In all reported problem cases, the issues were resolved by fixing hardware defects.? I don't recall any unresolved calibration problems reported here.
