Hi everybody,
i'm new in Espressif forum.
My order was: "ESP32: include a Modbus TCP server application over Etehrnet and WiFi"
My Platform for Arduino "ESP32-EVB" is: PlatFormIO ( newest: Home 2.0.0 ), and VisualStudioCode
platform.io:
[env:xxxxxxx]
platform = espressif32
board = esp32-evb
framework = arduino
board_build.partitions = default.csv
...
What i'm doing (after reading some examples) inside PlatFormIO:
1. append the new library "ArduinoModbus"
... compiling: he said missing "ArduinoRS485" ...
2. so i append the new library "ArduinoRS485"
3. i'm appending "lib_ldf_mode = deep+" in my platform.io, because installed libs are in:
"...\.platformio\lib\ArduinoModbus_ID5816"
"...\.platformio\lib\ArduinoRS485_ID5814"
My source modification is only 2 includes:
TEST1:
#include <ArduinoRS485.h> // ArduinoModbus depends on the ArduinoRS485 library
#include <ArduinoModbus.h>
the compiler said:
....
D:\orcad\spb_data\.platformio\lib\ArduinoRS485_ID5814\src\RS485.cpp: In member function 'virtual void RS485Class::begin(long unsigned int)':

Searching google for 'SERIAL_PORT_HARDWARE', found a: #define SERIAL_PORT_HARDWARE Serial1
but that makes no sense !!
TEST2:
i install the example: "5902/esp32ModbusTCP"
and again, only including the 3 #include files out of the example in my "Modbus_KE.cpp header":
#include <Arduino.h>
#include <WiFi.h>
#include <ModbusTCP.h>
=> error "ModbusTCP.h" not found ( and really it is NOT on my PC ! )
Everytime i'm installing another lib inside platformio ( PIO Home -> libraries )
i will get different errors.
I think there are some libs missmatched in the deep ?
Is there any way to solve this ???
Please help
By the way:
I need a ModbusServer example that uses also Ethernet and WiFi on a ESP32-EVB board ( or hardware: ESP32-WROOM-32 ).
It reads inside ESP32 board 10 Hz CAN-values and transmit it over Modbus-protocol Ethernet and/or Wifi to an external PC.
Greetings Wolfgang
