grove_ir_receiver compatibility

Thorvin commented 8 years ago

Hi, Combining grove_ir_receiver with grove_temp_hum, reading the sensor crashes my Wio in ~2 out of 5 calls. I could trace the crash to suli_delay_ms(250); in GroveTempHum::_read(). I did some more tests and it seems that any call to suli_delay_ms() causes a restart (sooner or later) when the IR Receiver is active.

Debugging console shows:

Boot reason: EXCEPTION
Node name: esp8266_node
FW version: 1.1
Chip id: 0x008b3609
Free heap size: 25072

In the Terminal connected to the micro-usb:

Could this be a general problem caused by the 50 µs timer interval in grove_ir_receiver?

Thanks, I will look into this.

Hi Thomas, It turns out to be a bug of ir receiver driver, and get fixed. Please OTA your wio link once again. Hope the fix works for you. And thanks again for reporting the issue.

Hi, Many thanks, looks good so far!

P.S. (Unrelated): The latest Version of the Android App shows a new "Wio Node" module when adding a device but I couldn't find it mentioned on the Seeed-Homepage? Just curious...

You're welcome.

Wio Node does exist, under manufacture. Will see it soon :D It's a smaller sized and cheaper Wio compatible board~
