Yeah, it's possible! You just need to make sure the modules use different communication protocols or assign different pins if they're both using something like SPI. The CC1101 typically uses SPI, and the PN532 can use I2C or SPI—so setting the PN532 to I2C might make things easier.

Hello, we are now deep into Septembe,r and while we have several projects on the ,go while planning projects for Halloween, I find myself looking to December.
I'm planning to publish 25 projects in December, one for each day, building up to Christmas. While this may be impossible to achieve, would anyone else be iinterestedin joining the challenge?
This Challenge is open to everyone, including the team at @M5Stack
Rules,

Must contain M5Stack products.
May usenon-M5Stackk Products, but they must be easy to get hold of.
Must be quick and simple projects
There is no prize unless M5Stack chooses to sponsor one.
Projects must be for fun, entertainment, or teaching others something.
Small projects can be connected to makea bigger project, butthey must work on their own.
Projects must be documented on hackster.io.
Projects must be fun!
Projects can contain a holiday theme.
A single project can be done by more than one person
Topic is Open to all ideas.
Only post 1 project per day.
First Post must only be visible after 12:01 on the 1st December.
Last project to be made visible before 10pm on the 24th December.

Hey ajb2k3, this sounds like a really cool initiative. I like the idea of short, simple daily builds leading up to Christmas. Having them documented on Hackster.io is a smart move too, makes it easier to follow and replicate. I'm currently working on a couple of M5Stack-based prototypes, so I might be able to adapt one or two for this challenge. Thanks for putting this together, looking forward to seeing what others come up with.

Hey @roanevic, just jumping in here, I’ve tried that same setup recently. The example code Kuriko linked is a good starting point:
https://github.com/m5stack/M5-RoverC/tree/master/examples/RoverC_JoyC_Remote

It’s designed for StickC, StickC Plus, and the StickC Plus2, so it should work with your hardware. Just make sure you have all the necessary libraries installed (like M5StickCPlus2, RoverC, and JoyC) in the Arduino IDE. Let me know if you hit any snags setting it up.

@俺がガンダムだ said in LVGL performance problem:

I applied LVGL on stickc-plus2，with TFT_eSPI's st7789v2 driver.But the refreshing rate is very low (while doing "load screen anim").I know stickc had good performance on drawing screen (by watching the video of M5stick T-Lite Thermal tutorial). And the LVGL also has a good performance through Dial-ESP32-S3 and Din-Meter demonstration video.

So what is the reason of such low performance. Cound it be the TFT_eSPI library?

I’ve seen similar issues on the StickC-Plus2. It could be due to TFT_eSPI settings, try increasing the SPI frequency or enabling DMA. Also, check your LVGL buffer config; full buffering helps with performance.
