setFont via JS API

[amizer12]

Hi,
Can you let me know how to properly send to the ffi function the font name when using this library via JS API ?
When i simply use
ILI9341.setFont(&FreeMonoBold9pt7b);
It doesnt work and throws a parse error, when i try to pass it as string or anything else it also fails.
Any pointers ?

I only use C on Mongoose OS. I'm sorry to say, because the javascript portion of this library was contributed, I do not use or maintain it directly. I cannot answer questions on its functionality - please take a look at the Mongoose OS gitter channel, perhaps you'll find the author or an active userbase there.

Thanks for your reply - i found the way to do it looking through some other issues in here - will post and update to README.md file to cover this as i`m sure a lot of people will have issues with it as well.

@amizer12 see here for how to work with fonts from js - https://github.com/mongoose-os-apps/example-m5stack-js/blob/master/fs/init.js#L72

this uses a function in C - https://github.com/mongoose-os-apps/example-m5stack-js/blob/master/src/main.c#L26

i guess we could upstream it here for reuse
