Atxmega - ILI9341

[slavaag7]

Hello
the problem is the slow download of ili9341 25-30 seconds.
atmega - fast
stm - fast
atxmega - slowly.
Is it a feature of atxmega?
What can I do?
Checked in the 'iron', the simulation is all right.

Hello,

Have you tried the 1 second flasher test on the ATXMEGA to confirm it is running at the speed you think it is.

Checked
changed the frequency in general options, led flashes on
Different. 1mhz faster than 20mhz slowly
included as in the project, the blinking of the led depends on
ili9341. Turned off the ili9341 componet, led flashes depending on the frequency exhibited.
The ili9341 component delays execution,
as if the delay is set.

The download of the display does not depend on the frequency on display.

Hello,

It sounds like the micro is running a lot slower then you think it is. Are you using a crystal or are you using the internal oscillator. How are you setting the config bits of the device, maybe these need changing?

[slavaag7]

There is no external quartz
I thought the internal RC generator is enabled software.
Insert on C? what would include an internal RC?
In project options, the configuration is empty.

Hello,

It looks like the default internal oscillator is set to 2MHz. It also looks lik eyou can change to a 32MHz clock but it looks like it's more then a single line of code.

Refer to section 7 in the datasheet here for more information.

Let us know how you're getting on.

Hello,
Found the code to turn on the internal generator
I ask you to look and listen to the advice.
It works fast.
I found another site where the inclusion of external quartz is described, I will study, I will write a check.

Hello,
Please let us know what you think about Box C. Your advice is needed.
In a project, two timers in one cycle slow down
Program execution. As if insert C is not working.
Sorry for the translation.

Another C code.
Works.
