Connecting Epaper display to m5stack core or other models ? (Waveshare)
-
Can you add a another screen to any of the m5stack models ?
I was wondering if I could use m5stack models to attach a epaper displays from waveshareIm just about to start fiddling (ordered a m5stack core) ...
And if so are there any guides on what pins to use etc etc...

If its and i2c screen then you can connect it to Port A otherwise you will need to use the 2x15 internal bus connector.
if programming in arduino, there are librarys available to install but for the stock firmware then it will be alot harder to use. -
Im total beginner at this , did a quick googling ... the l2c is the grove in this picture
when you talk about the internal bus connector ... then I would need to open the backplate ?
this is a example model of the epaper
Im assuming I have to use the internal connector ? judging from the epaper module picture ?
there is also a module for this : m5-bus modulewhich i can use instead of having the back open ? is this correct ?

ahh, its an spi device so will have issue with the internal spi screen.
There is an Epaper M5stack device in development but you would be better off with this device

Hi @ajb2k3
I am just curious - what makes you say the ePaper module will have issues with the internal screen? If I am not mistaken the SPI bus can be shared by multiple devices as long as each device has its own CS signal. For instance the M5Stack LAN module also uses the SPI bus and works nicely together with the internal screen.
Thanks

@felmue Interesting, I just read that sometimes SPI devices clash and cause issues.
