ΕΒΥΤΕ E22-400T30D support

InTranceWeTrust 22 May 2021, 17:17 last edited by

I just created a repo [https://github.com/mkoniari/MySensorsE32] with instructions / modifications for the ΕΒΥΤΕ E22-400T30D [https://www.ebyte.com/en/product-view-news.html?id=939] module (LoRa SX1278 SX1276 433MHz rf Module)

Tested with MySensors v.2.3.2 and LoRa_E32_Series_Library [https://github.com/xreef/LoRa_E32_Series_Library] v1.5.0
Hope you find it useful

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Hi, I'm glad CodeGarage is taking over! Please are there any updates since January what's happening? The GitHub repo hasn't gotten commits for over a year. Thanks!
No merge into master in the last 5 years, should we use development?

Well, my network with two handfulls of nodes in three different locations is still live and kicking! I agree that there does not seem to be a lot happening in the community. I'm running 2.4.0- alpha since this gives support for MQTT over TLS. Just managed today to create one more MQTT GW after reading a lot about support for ESP8266. You know, these things you do once per year and have to learn new each time. MySensors is the cheapest way I have found to create small sensor nodes etc. But now slowly running out of my supply of hardware. Well, time will tell...
Which device I have to use to connect with accelerometer before connecting to my pc?

When connecting an accelerometer to your PC, consider its communication protocol (I2C or SPI) and the appropriate interface device, like a microcontroller (e.g., Arduino). You may also need additional hardware for voltage adjustment or signal conditioning, depending on the sensor’s specifications.

@ZenBlizzard in case you are measuring the output with a multimeter, you will get an averaged level, since AC current waveform should be sinusoidal and overlapped with the Vcc/2->2.56V in your case. To measure the current you need a decently high sampling and some math. #define SENSITIVITY 66 // mV/A const float readings = 5; const float alpha = 2.0 / (2 * readings + 1); for (ifor = 0; ifor < 250; ifor++) { // Voltage voltageSampleRead = analogRead(V) * vccRead / 1023 - vccRead / 2; /* read the sample value including offset value*/ voltageSampleSum = voltageSampleSum + sq(voltageSampleRead); /* accumulate total analog values for each sample readings*/ voltageSampleOffsetSum = voltageSampleOffsetSum + voltageSampleRead; // Current currentSampleRead = analogRead(I) * vccRead / 1023 - vccRead / 2; /* read the sample value including offset value*/ currentSampleSum = currentSampleSum + currentSampleRead * currentSampleRead; /* accumulate total analog values for each sample readings*/ currentSampleOffsetSum = currentSampleOffsetSum + currentSampleRead; wait(1); } voltageMean = voltageSampleSum / ifor; /* calculate average value of all sample readings taken*/ voltageOffset = voltageSampleOffsetSum / ifor; reading = (sqrt(voltageMean) - voltageOffset) * 230.0 / 1.0; // read voltage / reported voltage. voltage = round_to_dp(alpha * reading + (1 - alpha) * voltage,1); Serial.println(voltage); if (voltage < 25) voltage = 0; currentMean = currentSampleSum / ifor; /* calculate average value of all sample readings taken*/ currentOffset = currentSampleOffsetSum / ifor; reading = (sqrt(currentMean) - currentOffset) / SENSITIVITY * 1000 - currentZeroOffset; // subtract no load current. if (reading < 0) reading = 0; current = round_to_dp( alpha * reading + (1 - alpha) * current,2);
