回答： Bob Snyder 2020-9-2

I have the following code as a simple test:

byte1 = in_data(5);

byte2 = in_data(6);

byte3 = in_data(7);

byte4 = in_data(8);

X=uint8([byte1 byte2 byte3 byte4]);

az_gyro=typecast(X,'single');

When I try to 'Build/Deploy' to my hardware I get the following:

"For code generation, integer input or result classes for TYPECAST must map directly to a C type in the target hardware. The class uint8 does not map to a 8-bit C type. "

What is happening here?

Good question. Seems like it should easily map to unsigned char. What is the target hardware?
