Update - sorting qstr and using binary search improve things significantly!

I've created a PR: https://github.com/micropython/micropython/pull/6896

Time to connect JTAG! Random breaks while importing mpy modules always end up at qstr_find_strn (gdb) bt #0 0x400d3734 in qstr_find_strn (str=0x3f819960 "set_value", str_len=9) at ../../py/qstr.c:181 #1 0x400d377f in qstr_from_strn (str=0x3f819960 "set_value", len=9) at ../../py/qstr.c:197 #2 0x400d...

Your compiled modules must be very large if loading from the file system takes several seconds. Are you sure that there is not still the .py version of the module in the files system. That will take preference. No, there is something else going on here. There are 13 .mpy files, total of 50KB. Not l...

Hi, I'm compiling modules for ESP32 with: mpy-cross -march=xtensawin The compiled mpy modules are imported, loaded and start running after boot. I expected these modules to be loaded very fast when imported since they are already compiled. However, it takes several seconds after boot until the modul...

Not sure if that's what you need, but here's an ESP32 XPT2046 micropython driver for lvgl:

I was just wondering, if anyone ever though or did some work of porting https://github.com/littlevgl/lvgl to Micropython? There is a port of Micropython to LittleVGL (which is the other way https://blog.littlevgl.com/2019-02-20/micropython-bindings or https://github.com/littlevgl/lvgl/issues/557 ) ...

Having pre-built binaries gives new developers the opportunity to get right to coding, testing, and evaluating LittlevGL without all the "building" hassles. We don't provide pre-built binaries. But for testing and evaluating Micropython + LittlevGL you can use the online simulator: https://sim.litt...

I just saw that it only supports resistive, it would be nice if if also had a generic touch driver, where from python you could just update a method .display_touched(x,y) for example. And the library would handle it. This way the implementation of the touch driver could be totally outside LittlevGL...

Which particular ILI9341 driver does this use? I've just started looking at this and want to test, but it's not immediately obvious to me. I've done a little more reading and figured it out. The driver is included with the binding: https://github.com/littlevgl/lv_binding_micropython/tree/master/dri...
