getting rid of data type conversions (5)

having just proved that I got no where with the interrupt mask, I had a look at the generated code and it is pretty long. One thing that I have been meaning to do is to remove all the data type conversions. That shoudld make it a bit more efficient.

start with the HE out block and change input to double

compiles, loads, does not run

I think that I tried that before -

try to change all to int16

compiles, loads, does not work

HE INPUT MUST BE UINT16!!

try to remove the converstions from IA capture where the divide is.

Works!!

in the same block, I changed the gain, the divide and the sum data type to "inherit via back propogation"

compiles. loads, Does not work

tried to change just the sum back to "inherit via internal rule" but that did not work

I have changed them all back to "inherit via interenal rule"

works again - try "same as input"

compiles. loads, Does not work

I assume that i am loosing some data - make it uint32 on the inputs

must be time to give that caper up.

changed them all back

works again

tried to remove the conversions from Ib and Ic capture

compiles, loads, runs


i have makd a whole lot of stuff double without any explicit conversion blocks

motor runs

made a whole lot more stuff double in Ib and Ic

works

made the output of HE_out double and also the input to rtdx

I have an issue with the size of the memory map

I have changed them back and will have a go altering the memory map

first step is to remove the rtdx and use the internal memory map

works

now try to change the things back to "double"

compiles - which is better than last time
loads
motor turns!!

made some stuff (including look up tables) in the reference generation block double

motor turns!!
