Hi Jorgen while we sort this out I have manually changed your v9 forum password. I'll send you it via a pm

Hello, The LCD (Generic Configurable) component has a property called remap characters that allows you to take a character and automatically remap it to a different character when printing strings. I beleive this is what you need. For example this macro would replace any occurance of the character '...

Hi Christian,

Yes Viktor is correct the ATMEGA328p lacks the period register and so the period is locked to 256 counts. There is a warning about this in the compiler messages but it's easy to miss.

Hi Abhi, In your calculation that converts from a float to a string try changing the code to this. ADC_Global_ST = FloatToString$ (ADC_Global_Real,1) ADC_Global_ST = ADC_Global_ST + " " This will add some spaces to the end of the string and avoid leaving values on the GLCD at the end of the number f...

Thanks Abhi,

What about this instead?

Hi Abhi,

Let me know how you get on with the example code, if that works ok then I'll use that for the component. There is a shift that i'm slightly unsure of so would be nice to confirm if the range is correct or /2.

e.g. 0-2047 instead of 0-4095.

Ooh if you don't mind that would be very helpful.

Hi Abhi,

I'll have a go at creating a component but here is an example using the SPI master component.

I haven't manage to get my hands on one of these displays so I'll get one purchased so we can investigate the problem for you.

Hi Rov,

Have you tried the SPI version of the component that uses the SPI hardware rather then a bit banged SPI interface. This should run a air bit quicker for you.

Hi Bob, Yes an interrupt firing at 15.2 Hz will run the selected macro 15.2 times a second. Your program looks ok but will likely be flashing at a rate of 0.5Hz. 1second on and 1 second off. The problem with your program is you are also calling the pop macro within your main loop, remove the macro c...

Should be fixed for you now.

Hello, It might be worth trying the SPI master component as this might give you more control over things like the clock speed and bus settings. Looking at the device datasheet SDO (MOSI) is on B0 and SDI (MISO) is on B1 and this seems to tally with what is in the definition file. When using the hard...

Hi Roy, Rather then go off into a similar macro for each test I now do the test inside the test macro, the .NumTests = .NumTests + 1 command simply increments the value in the NumTests variable so we know how many steps are in the test. Here is a snippet taken from one of your macros ported to the n...

Thanks for the code.

Maybe try a small delay (100ms) before calling the initialise function. Initialise does a refresh I beleive and if the chip isn't running at full speed when it does this then it may clock out incorrect data.

Hello,

Can we please see your program, my guess is it's something there that is causing the white output.

Hello,

I had a dig for my 1963 display but couldn't lay my hands on it. I'll keep looking to see if I can help.

PIC32 shouldnt be required.

I've had a stab at adding it in Flowcode v9, it's been a while since I did it so not sure how well implemented it got but it certainly was working on some devices.

What compiler / software are you using?

Excellent, thanks for letting us know and well done

Excellent, thanks for letting me know.

Hello,

An error is appearing when I try to record with pickit3.

What error message are you getting?

Hello,

I might know what's causing this. Please can you try changing the CAN component property SPI CHANNEL to software and let me know if this works correctly.

Are you driving the Atmega with a 16MHz crystal? Are your load capacitors correct? Can you post your circuit so we can check.

You settings look ok to me for 16MHz operation.

Hola,

La función ToString $ () debería hacer lo que quieras.


Hello,

The ToString$() function should do what you want.
