I use oscilloscope measure ESP32-S module PWM output, use:

machine.PWM()

when PWM frequency > 78125, it will be keep output high, this's ESP32 hardware limit? or MicroPython implement on ESP32 limit?

water

In my memory old version of MicroPython (I forgot which version), I2C can configure frequency likes freq = 400000 , but I can't do that in current version: i2c = machine.SoftI2C(scl = Pin(5), sda = Pin(4), freq = 400000) i2c SoftI2C(scl=5, sda=4, freq=500000) i2c = SoftI2C(scl = Pin(5), sda = Pin(4)...

Solved, lib/asf4 folder empty, execute

Code: Select all

git submodule update --init lib/asf4

build pass, but I execute

Code: Select all

git submodule update --init --recursive

from micropython root folder before, why lib/asf4 folder is empty?

water

Code: Select all

make submodules

from ports/samd

Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
Updating submodules: lib/asf4 lib/tinyusb

Code: Select all

make BOARD=ADAFRUIT_ITSYBITSY_M4_EXPRESS

The error above appear still.
But I success build some STM32 at same environment.

I try to build ATSAMD51 use make BOARD=MINISAM_M4 , return error below: Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity. mkdir -p build-MINISAM_M4/genhdr GEN build-MINISAM_M4/genhdr/mpversion.h GEN build-MINISAM_M4/genhdr/moduledefs.h GEN build-MINISAM_M4/genhdr/qst...

Since v1.15, micropython switched to cmake on the ESP32 port, breaking compatibility with user modules (likes ulab),
Is it mean I can't include likes ulab to MicroPython after v1.14 ? have some solutions except switch to v1.14 ?

Can I let Timer.counter() add 1 when Pin level changed.

water

.deinit() is affect to ESP32 port, I confuse them, on PyBoard, use sd.power() instead,
before eject SD card,

Code: Select all

uos.umount('/sd')
sd.power(0)

True

then re-insert SD card,

Code: Select all

sd.power(1)

True

Code: Select all

uos.mount(sd, '/sd')

If none SD card inserted, execute sd.power(0) or sd.power(1) will return False.

water

How to do that?

Thanks.
