EBYTE.h & WIRE.h #40

Closed Lucamenghini closed 2 years ago

Lucamenghini commented 3 years ago

Hi Kris another issue. I defined:

include "EBYTE.h"

include "Wire.h"

include "SHT31.h"

define SHT31_ADDRESS 0x44

SHT31 sht;

and in the setup i setted: Wire.begin(); sht.begin(SHT31_ADDRESS); Wire.setClock(100000);

I've got to use EBYTE to transmit, Wire to set the clock and sht31.h to manage a umidity&temeprature sensor.

I debugged the sketch because the transmitting doesn't work and I found that the line "Wire.begin();" doesn't not permit the transceiver to work How can I solve? please help me thank you bye

I doubt this will work but change the order

include "Wire.h"

include "EBYTE.h"

and try reordering the begins Wire.begin();Serial.begin(9600); Serial2.begin(9600);

Thanks, Kris @.***

reversing order will probably not work, stuff to try

  1. do you have to use wire.h? what happens if you exclude it? It looks like wire.h is either hihakking the serial port--the one the EBYTE needs or it's altering the clock frequency.

  2. try #include 3. Maybe even try wire.end(); before sending data (with some small delay)then after sending data, start the wire back up with wire.begin(); I have an ESP32 that uses and EBYTE and a dallas temp sensor and I'm using OneWire.h. The only reason I use and ESP32 as there is good support for connecting to an internet and hosting web pages--but honestly I avoid Arduinos and ESP's at all costs as there is just too many issues with those MCU's.  I use Teensy's exclusively, I have several serial devices connected to a Teensy 3.2 and worked the first time and every time--i'm not using wire.h though. Arduino UART is a mess and ESP is not much better Thanks,

Update on the last post above: I tried to switch on and then switch off the sht and then the Transceiver switch on and then switch off (init .... stuff .... reset) But nothing changes, the transceiver appears not available when SHT.begin(ADDRESS) is previously executed.

Try without the library. If the transceivers still don't work there is an issue with your hardware.

You only really need this library to program these EBYTE units. For reading data structures, you can call readBytes directly on the EBYTE Serial object

ESerial.readBytes((uint8_t*)& MyData, (uint8_t) sizeof(MyData));

for writing data structures you can call write directly on the EBYTE Serial object

ESerial.write((uint8_t*) &Data, PacketSize );
