Re: M5Atom
The red pixel moves forward as expected but additionally other pixels are flashing up randomly (once every 10 to 30 second or so). Interestingly those differ in color and intensity but follow the same cycle. This is a known issue. Basically, the neopixel module and ESP32's underlying RTOS do not pl...

Re: mdns support
Interesting,
However I'm not sure that this portion of code is compiled. I do not see where MICROPY_HW_ENABLE_MDNS_RESPONDER is being defined if at all.

Re: LVGL and SD Card won't share SPI bus
I just tried @pythoncoder's SDCard class. What happens is that: claiming the bus using SPI(1) fails because the HSPI bus is already in use (by the screen). I expected that claiming the bus using SPI(2) or SPI(2, sck=Pin(18), mosi=Pin(23), miso=Pin(19)) freezes the screen. furthermore one gets a "OSE...

What does happen during a soft reset?
The title says it all: what exactly does happen during a soft reset? Looking through the documentation, I only found an explicit reference in the WiPy section: A soft reset simply clears the state of the MicroPython virtual machine, but leaves hardware peripherals unaffected. There are many mentions...

Re: Allocate the emergency exception buffer more than once
Thanks.The source code is rather clear. The only thing is that I would not have found it alone: sometimes one can be overwhelmed by the amount of files to search into.

Allocate the emergency exception buffer more than once
Just an odd question. What happens if one allocates the emergency exception buffer (via alloc_emergency_exception_buf) more than once? Is the memory used for the first allocation lost, reallocated or anything else? I ask this since, as a sloppy programmer, I sometimes use alloc_emergency_exception_b...

Re: Check for valid bytes
What do you mean by garbage? The sample output you give is composed of 13 bytearrays of length 4. When printing them (micro)python only escapes the bytes which do not have ans ascii representation.

Re: Confusion about micropython.const
Look there: http://docs.micropython.org/en/latest/reference/speed_python.html#the-const-declaration As far as I can tell, when you write foo=const(42) then foo is not a variable but behaves as if, as compile time, it is replaced by 42 . So your code would be seen as: from micropython import const cl...
