Problem new sdm library

[crywolf87]

helllo,

I 'have upgrade a new library sdm, but the esp12F doesn't works.

I have insert to the sketch this line like the guide: `#include

include

define USE_HARDWARESERIAL

SDM sdm(Serial);

voidsetup(){ sdm.begin(); }`

voidloop(){ s = String(sdm.readVal(SDM220T_VOLTAGE, 1)); if (s != "nan") { s.toCharArray(charBuf, 50); }

in the SDM_config_user.h `#define USE_HARDWARESERIAL //define USE_HARDWARESERIAL

//------------------------------------------------------------------------------

define SDM_UART_BAUD 2400 //define user baudrate

//------------------------------------------------------------------------------

//------------------------------------------------------------------------------

ifdef USE_HARDWARESERIAL

define SDM_UART_CONFIG SERIAL_8N1 //define user SDM_UART_CONFIG

/*

define SWAPHWSERIAL 0 //define user SWAPHWSERIAL, if true(1) then swap uart pins from 3/1 to 13/15 (only ESP8266)

*/

endif

//------------------------------------------------------------------------------

define MAX_MILLIS_TO_WAIT 500 //define user MAX_MILLIS_TO_WAIT to wait for response from SDM

`

but the esp donn't works.

can you help me ?

thank's in advantage

Paste whole code (complete sketch and complete SDM_config_user.h after changes), use correct formatting: https://help.github.com/articles/creating-and-highlighting-code-blocks/

Show the wiring diagram with ESP <-> RS485 <-> SDM

I don't understand "esp12F doesn't works"?? If esp12F doesn't works then replace it with a new one.

Doesn't work for me with wemos and HARDWARESERIAL, got values as Nah... With old library no issues. I see that there is no RX and TX pin defining anymore

hardware serial does not have pins definition, it is always GPIO3/GPIO1.

If you want to use HARDWARESERIAL mode then you must uncomment #define USE_HARDWARESERIAL in _SDM_ConfigUser.h (by default it is commented) https://github.com/reaper7/SDM_Energy_Meter#configuring

My SDM_Config_User.h looks like:

define USE_HARDWARESERIAL

define SDM_UART_BAUD 2400 //using SDM120

define DERE_PIN NOT_A_PIN

ifdef USE_HARDWARESERIAL

define SDM_UART_CONFIG SERIAL_8N1

define SWAPHWSERIAL 0

endif

define MAX_MILLIS_TO_WAIT 500

[reaper7]

looks OK.

it should not make a difference, but try this SDM_Config_User.h:

#define USE_HARDWARESERIAL
#define SDM_UART_BAUD 2400 //using SDM120
// #define DERE_PIN NOT_A_PIN
#ifdef USE_HARDWARESERIAL
// #define SDM_UART_CONFIG SERIAL_8N1
// #define SWAPHWSERIAL 0
#endif
// #define MAX_MILLIS_TO_WAIT 500

I also use wemos with hw serial (compiled 5 days earlier) and my works.

What type of converter you use? Show the diagram or photo of the whole device.

define USE_HARDWARESERIAL

define SDM_UART_BAUD 2400 //using SDM120

// #define DERE_PIN NOT_A_PIN

ifdef USE_HARDWARESERIAL

// #define SDM_UART_CONFIG SERIAL_8N1 // #define SWAPHWSERIAL 0

endif

// #define MAX_MILLIS_TO_WAIT 500

did from scratch and all works, strange :)
