Thanks Steve,

I must have hit the toggle by mistake sometime... Been running like it for weeks too

It might be a configuration setting - but I've noticed that properties seems to get the variable name displayed rather than the description...

... The modified component code imports glcd_ssd1963 (parallel) and is using this for the read & write routines (and others).

So modifying this would be one way to go.

Alternatively - as a test - write a tiny component or program to test the display. This doesn't need to be very large - it needs ...

I tested this - I modified your component (slightly - gave it a new GUID changed the name) and compiled to SSD_TEST - then compiled the test program having modified it to use the new component and removed the old component. The new component moved to development - with name SSD_TEST

Have no way of ...

This might give a solution:


#include <math.h>
#include <stdio.h>

int main()
{
int a, b;

// Using typecasting for
// integer result
a = (int)(pow(5, 2) + 1e-9);
b = round(pow(5,2));
printf("%d \n%d", a, b);

return 0;
}



Which looks to give the correct result on both cases (from ...

It might be because it uses floating point...

pow(2, flt_fromi(FCL_I));

- not sure why it doesn't also do flt_fromi(2)?

However - it shouldn't make it so wrong ?

Wrote my own integer

Just spent a while chasing a bug in my code - but it turns out 'pow' returns an incorrect value.

It actually returns the result - 1 (except for pow(2, 0) and pow(2, 1))

The attached demonstrates this behaviour (on an Arduino - other devices may differ?):


2**0 = 1
2**1 = 2
2**2 = 3
2**3 = 7
2**4 ...

I did a quick component - assuming unused macros are optimised away.

This supports SetBitfield8, 16 and 32 (on an 8 bit MCU 16 and 32 bit shifts are rather slower)
GetBitfield8,16 and 32
SetField4bit and GetField4bit - set or retrieve a field using a byte where upper nibble is position and lower ...

And I went with 4 bits (nibbles) each for width and position.

Make every byte count

Currently I need to use bitfields in some code.

On a PIC I can do REGISTERbits.FIELD = value for register values. I wanted a simple way to do this for variables.

I could define two constants field_start, field_width

.mask = pow(2,field_width) - 1
.value = .value & .mask // Check the value will ...
