With development branch running as per above, I connected the motor shield, attached as per photo.. The interesting thing is that with the shield on there is power to the track even when the OLED says power off. However, with track on or off although I can see volts on the track no command gets sent (loco will not respond).... This seems to support the behavior without a shield on where I get over-current faults. I must be missing something (or faulty hardware?)
I will add that the motor shield works fine - it is the one I use on my Arduino Uno DCC++ station and it is faultless!
I am not sure what the LEDs on the shield show. On my DCC++ they are off until I enable track power on the station. When I enable power both pairs of LEDs for A and B light up. On the ESP32 I get the "2nd" LED of output A lit permanently when the ESP32 is powered up - and no others when I do anything else. (By the 2nd I mean the one closes to the B output.
There is an LED on the ESP32 that flashes continuously - not sure what it indicates. However, it is on pin 25 so I suspect that may be one issue.
I just retried the development branch build with the RHS pins 12,13,14,27. I thought if I connect each output with an LED between itself and GND I might "see what's going on". Basically the LEDs are lit for 12, 13, 14 but not 27. Toggling the power doesn't switch any of them - although there may be an instantaneous switch off-on on the ENABLE_PIN_MAIN
These are sourced from the pins_arduino.h that is included via the Arduino.h file. The specific pins_arduino.h file that gets picked up is based on the board type you define in platformio.ini. Which board type did you pick in the ini file? Can you also open a terminal and run "platformio run -v" and paste the output from the compilation phase? It doesn't need to be the full output (it will be huge) but one showing the compiler options passed into the ArduinoFramework compilation phase. It may have the options in a "long options" file prefixed with an @ sign. Nope, not missing anything... I updated the file last night after posting to remove the ifdef/endif around the NextionInterface.h so that it is always included, you can see that in the latest development branch on line 90.
the wiring looks ok, I think. It is possible the ESP32 board has some of these pins in use by other hardware that we haven't taken into account. double check wiring, the lights should be the same as on the Arduino Uno. either all on or all off depending on track output. With the lights coming on (even one of them) with the track power set to OFF on the base station it would appear that one (or both?) of the enable pins is incorrectly held HIGH by the ESP32 board. I'd suggest shift both of the enable pins to a different pair and see if that works. If that LED is flashing with the track power OFF then that means it is being used by the board for something else and we should move the MAIN track enable pin to another pin. whichever pins you have selected for DIRECTION will almost always remain on due to the frequency at which the polarity shifts as part of the DCC signal. With track power OFF though the ENABLE pins should remain LOW (GND) so the LED should be OFF. This heltic board may take some experimentation to find a set of pins for ENABLE/DIRECTION/CURRENT_SENSE that work reliably. Since the board has a built-in OLED and non-standard I2C pin assignments there is bound to be a few pins that are used by the board itself.
I run out of terminal output (it replaces the lines) so this is all I could capture...I will also capture the non-verbose output Processing heltec_wifi_kit_32 (framework: arduino; lib_deps: SPI, ArduinoJson@5.13.4, AsyncTCP@1.0.3, ESP Async WebServer, ESP8266_SSD1306, LiquidCrystal_PCF8574, ESPmDNS, Wire, EEPROM; build_flags: -DCORE_DEBUG_LEVEL=ARDUHAL_LOG_LEVEL_VERBOSE; monitor_speed: 115200; platform: espressif32; board: heltec_wifi_kit_32; lib_ldf_mode: chain+; board_build.partitions: minimal.csv; lib_compat_mode: 2) ------------------------------------------------------------------------------------------------------------------------------------- Library Storage: C:\Users\andre.DESKTOP-TLMQMS5\Downloads\DCCppESP32-development\DCCppESP32-development\.piolibdeps Looking for SPI library in registry Warning!

Found the issue with the OLED defines... Here is the pins_arduino.h that was picked up by your build: https://github.com/espressif/arduino-esp32/blob/master/variants/heltec_wifi_kit_32/pins_arduino.h It doesn't seem to have the defines, but this one does: https://github.com/espressif/arduino-esp32/blob/master/variants/heltec_wifi_lora_32/pins_arduino.h I suspect an update is going to be needed on the heltec_wifi_kit_32 pin definitions. This explains why you had to add the defines yourself.
So I will use an LED trying to find a pin where the LED is not lit when I power it up, then update the enable/dirn/current sense to those I find we may have a way - just by systematically trying....Can I do any damage just by connecting an LED between any pinout and GND?
you may want to connect a resistor with the LED to ensure you don't send too much current to the LED. For the current sense pins, those will need to be any of the ADC1_? inputs, many of these are input only so they shouldn't be a problem.
OK, so I ran through that. Most of the pins on the RHS have voltage. Now I know some of these still may be used for other things, but, those that didn't light the LED are: 17, 5, 18, 23, 19, 22, 21 27, 34, 39, 38, 37, 36 Therefore i went for the following: #define MOTORBOARD_ENABLE_PIN_MAIN 27 #define MOTORBOARD_CURRENT_SENSE_MAIN ADC1_CHANNEL_0 //(pin 36) #define MOTORBOARD_ENABLE_PIN_PROG 23 #define MOTORBOARD_CURRENT_SENSE_PROG ADC1_CHANNEL_3 //(pin 39) #define DCC_SIGNAL_PIN_OPERATIONS 19 #define DCC_SIGNAL_PIN_PROGRAMMING 28 This, without the motor shield, seems to work. I will try the motor shield over the weekend. I also believe the JMRI error is caused by the network not connecting properyl. I have 2 routers. One it doesn't seem to like!!
Your pin selection looks good. I'd say give it a try and hopefully it will all work well. Sent from my ONEPLUS A5010 using Tapatalk
I decided to try this on a pololu shield instead. I changed Config_MotorBoard.h to show: #define MOTORBOARD_TYPE_PROG POLOLU Is that the only change I need? I then connected as I had used for my DCC++ Arduino Mega: 5V ESP32 -> shield VDD GND ESP32-> shield GND Pin 27 (MOTORBOARD_ENABLE_PIN_MAIN)-> shield pin D2 Pin 36 (MOTORBOARD_CURRENT_SENSE_MAIN)-> shield pin A0 Pin 19 (DCC_SIGNAL_PIN_OPERATIONS) -> shield pin 12 (M1DIR) Pin 23 (MOTORBOARD_ENABLE_PIN_PROG) -> shield pin M2PWM Pin 39 (MOTORBOARD_CURRENT_SENSE_PROG) -> shield pin A1 Pin 18 (DCC_SIGNAL_PIN_PROGRAMMING) -> shield pin 8 (M2DIR) I have the traces cut on the jumpers for pins 12, 10, 4 Initial testing suggests it's not working, so, does this seem correct - I wonder if I should be connecting M1PWM in place of D2?
I'm also now wondering if I have connected power correctly... Should I be taking the 5V from the ESP32 to Vin rather than VDD (or 5V on the Arduino Motor Shield)
