Compiling with makeEspArduino

[dom96]

Hello and thank you for this amazing library!

I have gone back to an old project of mine (from the 1.x days) and have wanted to update to the latest and greatest version of this library. Unfortunately I noticed that as soon as I change to version 2.0 I start to see artifacts in the display. Hard to get on camera, but basically the pixels are lit up as before but with slight ghosting flickering on/off as well as the lit up pixels flickering (but not from off to on, just from fully bright to less bright).

I played around with the settings in HUB75_I2S_CFG and couldn't resolve the issue. Any ideas what the cause might be? What was it that changed significantly in 2.0 that could cause this?

I can reliably switch back to 1.2.4 and the issue goes away, so there is definitely a change in 2.0 that is causing this.

Cheers!

Firstly, thanks for the kind words. Have you fiddled with the clkphase and latch blanking values? Did that make any difference?

Can you give the git version a try and see if that fixes anything? Otherwise I'll take a look.

[mrcodetastic]

No problems. I've made a change to the master version so hopefully it now works as well. If you could test that would be great.

Nice. That resolves the platform_detect.hpp issue but now I get linker errors:

I can't replicate that issue, but I don't use makeEspArduino. There must be a missing define.

If trying to compile for the original ESP32, the ensure you're defining 'CONFIG_IDF_TARGET_ESP32' as part of your build

[dom96]

That works, thanks.

For others using makeEspArduino: just had to add CPP_EXTRA=-D CONFIG_IDF_TARGET_ESP32 to the makefile.

Btw what do you use for building/flashing your code? PlatformIO?

I'll likely use a tagged version from now on in any case, so 2.0.7 for now. I guess the main thing that's new in master is S3 support?

[mrcodetastic]

I have built these library for use with PlatformIO and the Arduino IDE.

Yep, stick with 2.0.7 if it works as there's no benefit to the master branch unless S3 support is required.
