Hi
 
I've made a new kernel Auxiliary Display Driver for TM16XX and compatible LED controllers. This driver supports various LED controller chips, including TM16XX family, FD6XX family, PT6964, and HBS658. It provides support for both I2C and SPI interfaces.
 
I wanted it to manage the hardware on the kernel space while having an easy sysfs user space interface. It also aims to reduce the code to maintain by relaying on existing kernel features instead of recoding them. Plus, you can switch to hardware i2c/spi (instead of software gpio) depending on the pins used.
 
You can use "vfdconf-convert" to convert your existing vfd.conf to its device-tree version.  Or you can use the already converted vfd.conf of https://github.com/arthur-liberman/vfd-configurations that are listed in the device table.
 
You don't need to manually edit your device tree, the "make" command will apply the device tree source overlay to your dtb.
 
It comes with a service written as a simple bash script. So it's easily customizable without having to write custom C code.
 
Instructions and source code at https://github.com/jefflessard/tm16xx-display/
 
Could you please give it a try and report your feedback? 

I have added rk3566-h96-max-v56 to the repo. You could try with this one.
 
I think the JianPian is very similar to H96 Max V56 so I made this config file from this post.
 
This is a blind attempt... I have no much info on the JianPian and I have no way to test the config. Let me know if it works for you.
