Re: Why RTC.alarm() not available on ESP32 , have some difficult point ?

Without RTC alarm how can I wake from lightsleep every 60sec ??? Currently I'm doing a Bluetooth scan every 60 seconds... tm.init(period=60_000, mode=Timer.PERIODIC, callback=ble) Scan takes < 10 sec then waits for interrupt to go again. I get a very accurate timestamps. But I like to be in a sleep ...

Re: Bluetooth conflict with LittlevGL ili9341 driver

To date I have yet to find a solution for the Bluetooth scanning function becoming disabled due to its interaction with LVGL. I have created this very short routine for anyone who might like to take a shot at it. import ubluetooth, utime from machine import Timer from micropython import const import...

Re: How to "return" result from _IRQ_SCAN_RESULT

Would using schedule in "elif event == _IRQ_SCAN_DONE:" be an acceptable method to pass data...

Code: Select all

rssiValue = None
def bt_irq(event, data):
    global rssiValue
    if event == _IRQ_SCAN_RESULT:
	rssiValue = rssi
    elif event == _IRQ_SCAN_DONE:
        schedule(func, rssiValue)

Re: LVGL and SD Card won't share SPI bus

No. I have never used the ILI9341 micropython driver in any of my littlevgl projects. At this point I have no reason to switch to the micropython driver as the modified C driver does what I need. It's a case of "if it's not broken, don't fix it". Mike How would I go about adding the modxpt2046.c to...

Re: Build micropython with IDF v4.0.1 error

FYI... somewhere along the line
_IRQ_SCAN_RESULT = const(1 << 4) changed to cont(5) and
_IRQ_SCAN_COMPLETE = const(1 << 5) changed to cont(6)

Re: BLE Scan forever stops after 7+ Hours

Oh... they did backport it to v4.0 but they just re-used the same tag. Argh. This cursed chip. Anyway. To test this out. In your esp-idf repo, git fetch origin git checkout origin/release/v4.0 git reset --hard HEAD git submodule update --init --recursive git rev-parse HEAD The last line should be a...
