You simply have to modify your loss function in order to minimize the difference between predictions and scaled inputs.

This can be done using model.add_loss.

Considering a dummy reconstruction task, where we have to reconstruct this data:

It is a difficult question, in fact.
For element-wise division in particular, let say ai and bi are scalars. if ai = 0 and bi is not zero, then ai/bi = 0, but what if ai = 0 and bi = 0, ai/bi = ? 0?
Even worse, if ai is not zero and bi = 0 then ai/bi is NaN! So if the divisor is a sparse tensor, it will raise (possibly lots of) NaNs, unless the indices of both sparse matrices are the same. Same problem if you divide a dense matrix by a sparse matrix.

There is a nice a workaround to multiply two sparse tensors element-wise here, based on the relation (a+b)^2 = a^2 + b^2 + 2 ab.
It is also possible to compute the inverse of a sparse tensor C: tf.SparseTensor(indices=C.indices, values=1/C.values, dense_shape=C.dense_shape).

So there is this NaN issue for division, and concerning the mixture of dense tensor and sparse tensor, one option consists in converting the sparse tensor to a dense tensor. But we want to avoid this. In the other direction, from converting the dense tensor to a sparse tensor, this can be very ineffective if the tensor is not really sparse.

All this to say that it does not seem to be a simple problem.

Here's an example that changes the "Check" button to Green when Button3 is selected, followed by Button7 being selected, otherwise it changes the "Check" button to Red.

The buttons are arranged in a standard keypad grid:

After trying suggestions from the comments, this cleared out the error. I included the library outside the scope after extern "C" and changed the parameters of GuiLib_ShowScreen() to their native types, defined in the library as #define GuiConst_INT16U unsigned short. There was a compatibility issue placing the include statement within the scope, and because my original error stated previous declaration with 'C++' linkage it seems apparent that the include statement was interpreted automatically as a C++ header instead of C.

The constructor

Arduino Studio IDE has a flaw regarding compilation: only files in src subfolder of the sketch gets copied to the tmp folder and compiled. So all non-standard libraries should be placed in src subfolder in sketch folder.

Note that the AD9850 does not really have an SPI interface, but the timing of the serial interface does seem to be compatible, so you may be able to use an SPI master to write to the AD9850. However, another pin (FQ_UD) is required to update the data.

The main problem is, as you already suggested, that it does not have a chip select (CS) input. This means that all data on the serial interface will be clocked by the AD9850. The behavior for parallel mode is clearly documented in the datasheet:

In the parallel load mode, the register is loaded via an 8-bit bus; the full 40-bit word requires five iterations of the 8-bit word. The W_CLK and FQ_UD signals are used to address and load the registers. The rising edge of FQ_UD loads the (up to) 40-bit control data-word into the device and resets the address pointer to the first register. Subsequent W_CLK rising edges load the 8-bit data on words [7:0] and move the pointer to the next register. After five loads, W_CLK edges are ignored until either a reset or an FQ_UD rising edge resets the address pointer to the first register.

According to my interpretation, this means that if you would write 10 bytes to it, the first 5 bytes are stored (and will be "activated" using the FQ_UD signal), and the last 5 bytes are ignored. This is problematic in your use case.

For serial mode, the exact behavior is slightly less documented, but it seems to be approximately the same:

In serial load mode, subsequent rising edges of W_CLK shift the 1-bit data on Pin 25 (D7) through the 40 bits of programming information. After 40 bits are shifted through, an FQ_UD pulse is required to update the output frequency (or phase).

So what can you do?

• The best solution would be to use a dedicated interface for the AD9850. This would require 3 pins and give you full control over all devices. I highly recommend this if you have the possibility to do this (that is, if you have control over the hardware and enough free pins available).

• If you only need to write to the AD9850 during startup, you could probably make it work by first configuring the AD9850 (with the chip selects for the TFT displays disabled) and then configuring the displays (while never toggling FQ_UD, so the configuration of the AD9850 will not be updated anymore). This depends on your specific use case and I doubt it will be the case.

• I also was wondering if you could "flush" invalid data input to the AD9850 by toggling FQ_UD and then immediately writing the correct configuration afterwards. However, this seems dangerous because there are certain control codes that may brick the device:

  There are specific control codes, used for factory test purposes, that render the AD9850 temporarily inoperable. The user must take deliberate precaution to avoid inputting the codes listed in Table II. If you can guarantee there will be no invalid codes and you can accept invalid configurations for a short time, this is something you could consider, but I think it's asking for troubles.

NB: My first advice would be to do some tests with the AD9850 to confirm if my interpretation of the datasheet is correct. It's quite common for serial interfaces to be implemented with a shift register, in which case only the last 40 bits will be used (instead of the first 40 bits). IMHO, the datasheet does not explicitly confirm or deny this. If it does use the last 40 bits, it would be quite trivial to share the pins.

Ok I found the answer. Because the model is expecting the input_1 name, then in _get_serve_image_fn, I need to create the dictionary key, such as:
