float point in properties

[Rudi]

hi guys
no hurry,

discover just the "diversity" ( vielvalt )
and stumble a bit.

how do I get the float results in the properies advertisement?

so far I only get completely charged at a calculation.
if I have a float test number Enter H in the formula,
then it is displayed.
what am I doing wrong?

Code: Select all

.tmpCPUCLK = ::Component .Property .GetValue (this,"FCV_CPUCLK")
.tmpPREDIV = ::Component .Property .GetValue (this,"FCV_SPI_CLK_PREDIV")
.tmpCNTDIV = ::Component .Property .GetValue (this,"FCV_SPI_CLK_CNTDIV")

.tmpCPUCLK_HZ = .tmpCPUCLK * 1000000
.tmpSPICLKFREQ = .tmpCPUCLK_HZ / (.tmpPREDIV * .tmpCNTDIV)

::Component .Property .SetValue (this,"FCV_SPI_CLK_FREQ", .tmpSPICLKFREQ)


.tmpCPUCLK_HZ = .tmpCPUCLK
.tmpSPICLKFREQ_MHz = .tmpCPUCLK_HZ / (.tmpPREDIV * .tmpCNTDIV)

// will be a int
::Component .Property .SetValue (this,"FCV_SPI_CLK_FREQ_MHz", .tmpSPICLKFREQ_MHz)

// only for a Test: will be a int in properties
// ::Component .Property .SetValue (this,"FCV_SPI_CLK_FREQ_MHz", (10 / 3))

// only for a Test: will be a float in properies
// ::Component .Property .SetValue (this,"FCV_SPI_CLK_FREQ_MHz", 3.1428 )

thanks!

Hi Rudi,

Assuming .tmpCPUCLK_HZ,.tmpPREDIV and .tmpCNTDIV are integers try typecasting to a float.

Code: Select all

.tmpSPICLKFREQ_MHz = FLOAT .tmpCPUCLK_HZ / FLOAT (.tmpPREDIV * .tmpCNTDIV)

Hopefully this will do the trick, certainly caught me out before.

If this doesn't work then another trick is using constants e.g. instead of 10000 you would use 10000.0 to signify it is a float and perform the typecast.

hi benj
thanks for the help!
did not want to disturb you at night.
exactly brought the desired result, many thanks!

just endvertex many things and paths which I had not yet used.
ye have done really great work in the api.
so many possibilities.
hope you can still the EV_replace FC6 realize I, if not, then we are happy with it in the FC7

btw: (H) stands for Hardware

tv broadcasting done with I2C, we have now the same and more more other possibles with (H)SPI
