DEV 1143 and reset

Postby rosenrot » Fri Apr 21, 2017 7:19 am

I do have a TCP client implemented and I do wait for data and writing it to an apa102 led strip.

Code: Select all

while True:
    data=sock.recv(1024)
    esp.apa102_write(pin1,pin2,data)


If I send data via the TCP every 0.01s, the esp8266 runs into the dev 1143 error randomly.

I found here http://bbs.espressif.com/viewtopic.php?t=2615 that this occurs when a client tries to connect when a I/O interrupt happens. for me it seems to happen when I do receive data at the same time I try to write to the apa102.

Does anyone have an idea how to solve this?
Can I somehow disable interrupts while writing to the apa102?
Maybe using the Neopixel implementation could work?

You could try machine.disable() and machine.enable()

In 1.8.7 this should be machine.disable_irq()? http://docs.micropython.org/en/latest/wipy/library/machine.html#machine.disable_irq
I guess this would be time critical? I read that one should not disable irqs for more than 50us?

I think if you just introduce a very few microseconds of delay/sleep in your code, will let the RTOS, in which Micropython is embedded in, handle the WiFi stuff and avoid the reset.

Of course you must calculate the delay with you favoured refresh rate of the display.
