Re: LoRa module with hardware serial

I hope the modification in the LoRa library matches also with my problem with the Lotus Cortex-Mo+ and <RHutil/atomic.h>.

Re: Lotus Cortex-M0+ no serial output

I'm tring to use the Grove LORA 433 on Serial1 but the porting from Seeedstudio of the Radiohead library isn't working because fatal error: RHutil/atomic.h: No such file or directory #include <RHutil/atomic.h> So, I'm trying to use the original Radiohead library, but it seems that's isn't would to c...

Re: Lotus Cortex-M0+ no serial output

Ok, thanks for your reply.
The SerialUSB port (old Serial) now it works, but I still have some problem with the Serial1... is still named Serial1?

Lotus Cortex-M0+ no serial output

I would want to upgrade an old my sketch, that are currently running on a Seeeduino Loutus, with the new Lotus Cortex-M0+ board but I've no output on serial (and neither on Serial1 too) with this new on board. To investigate more I've tried to load the basic example blynk.ino, to test If I'm able to...

Re: Multichannel Gas Sensor with MKR1000

Point 1: already present on my sketch.
Point 2: modified the cpp as your direction but with NO LUCK... now I pass the initialization of the sensor but it freeze when I try to read a measure (note that the sensor work also with WIO node).

4-Channel SPDT Relay make MKR1000 hangs

I'm triing for make works MKR1000 with 4-Channel SPDT Relay, but even if the relay board is connected (via I2C) or not... it's sufficent to insert in the sketch the declaration #include <multi_channel_relay.h> Multi_Channel_Relay relay; to hangs the MKR1000; the most strange fact is that the MKR boa...

Multichannel Gas Sensor with MKR1000

I've two Multichannel Gas Sensor and no one talk with MKR1000. First guess is oriented to the I2C voltage level of the MKR that's 3.3V so I've tried with a Seeeduino 4.2: first a 5V and all was good, then I switched at 3.3V and tried again... the Gas Sensor still works! So... why works a 3.3V with S...

LoRa RF95 home network. What to expect?

I'm building a little domestic LoRa network, I would want to use a lora module (mounted onto a SAMD board) as "gateway" that will route oncoming RF packets RF to a MQTT server; I've some RF devices on my network that asynchronously sends data... so, my question is: what appen if multiple devices tra...

LoRa module with hardware serial

Hi folks, I would want to use a LoRa module with a board with multiple serial like Mega but the library published by seeed studio seem to be concepted to use with only software serial. I tried also to use the RadioHead "cousin" library (actually the seeed studio library seem to be a fork of radiohea...
