Some extra steps to get it working on M5Stack

[GunterO]

Hi, thanks for your library, really nice work! Anyway. I'm testing with a M5Stack Basic (black), on Windows 10 with IDF v4.1, and I had to take some extra steps to get it working. I'm quite a newbie here, so sorry if I made mistakes or are missing the obvious.

On compiling ($ idf.py build), I got these errors:

To make them go away, I had to go into $ idf.py menuconfig and set this:

And then the compiler gave no errors.

On uploading it to the device, all the colors were inverted. So I had to set:

Which made it run perfectly.

Is this as expected?

Yes, you are required to configure settings to match your dev board or device. There are ready made config files for different boards. I use sdkconfig.m5stack with M5Stacks. It should work with the black version too. Instructions how to use ready made config files are in the README:

$ git clone git@github.com:tuupola/esp_effects.git --recursive
$ cd esp_effects
$ cp sdkconfig.m5stack sdkconfig
$ make -j8 flash

Hi, thanks for your quick response. Yes, this is the first step I did: $ cp sdkconfig.m5stack sdkconfig But the e.g. CONFIG_AXP192_GPIO0_LDOIO0_VOLTAGE_BIT74 setting, where axp192_config.h is referring to isn't in there.

Ah then it is a bug. I think I have updated the AXP192 library but not the default config files yet. Will check.

I updated the AXP192 module to have default config values even when it is not used. Just tested and myself and both of the following now compile.

$ cp sdkconfig.m5stack sdkconfig
$ make -j8

$ cp sdkconfig.m5stack sdkconfig
$ idf.py build

@GunterO Did this fix the problem for you too?

[GunterO]

Yes, it did, thanks! I'll close the issue.

Thanks for the heads up! I had not compiled it for M5Stack for a while so missed the problem myself.
