ESP32 port of 2.1.9 firmware

[polskifacet]

I grabbed the new one and made pin changes etc. Same error coming up.

How you compile this firmware? I tried but too many error.

[v1pr]

read the readme and the previous posts (the FW still not works, but you can get rid of the errors)

[v1pr]

@Ray: the error is in the OTF library somewhere 🙁 Do you’ve any idea what can be behind it?

assert failed: tcpip_send_msg_wait_sem IDF/components/lwip/lwip/src/api/tcpip.c:455 (Invalid mbox)

The error is within somewhere in localServer.begin();

[usydow]

@V1pr
I have found a workaround!
There seems to be no WIFI connection, so the start of the web server goes nowhere.

DEBUG_PRINT(“ETH enabled: “);
DEBUG_PRINTLN(useEth);
DEBUG_PRINT(“Wifi mode: “);
DEBUG_PRINTLN(( get_wifi_mode() == WIFI_MODE_STA ) ? F(“STA”) : F(“AP”));
–> start_network_sta(“myssid”,”mypassword”);
// FIXME, just for testing
//::start_server_ap();
delay(500);
if((useEth || get_wifi_mode()==WIFI_MODE_STA) && otc.en>0 && otc.token.length()>=32) {
otf = new OTF::OpenThingsFramework(httpport, otc.server, otc.port, otc.token, false, ether_buffer, ETHER_BUFFER_SIZE);
DEBUG_PRINTLN(F(“Started OTF with remote connection”));

[Ray]

I have not followed this thread closely because I haven’t compiled the firmware for ESP32. But the OTF library is designed to support ESP32 as well.

[v1pr]

@usydow great, I was thinking the same (that’s why the start AP is there). There is a glitch in the whole flow somewhere 🙁 upon the first start (after factory reset), the controller should start an AP, which happens later than wifiserver begin… Logically this should not work on the original esp8266 either…

@Ray,the esp32 otf is missing the flush/close for sure

[v1pr]

@usydow: thanks for the finding, I’ve fixed it.

@Ken.238 @polskifacet please download the latest/refresh. Everything should be fixed know, no workarounds needed (platformio should update espressif32 platfrom automatically for correct version)

[Ken.238]

It compile without error but once wifi start keep factory reset. Below is I copy from platformio serial monitor. Thanks for hard work.

@v1pr, you said “Logically this should not work on the original esp8266 either…” — I don’t understand what this is referring to. Did you mean some line of code should have appeared before some other line of code? If i had to take a guess: note that creating ESP8266WebServer merely creates the object, it doesn’t do anything yet and certainly does not require having WiFi ready at that point. Same with creating the OpenThingsFramework object. The WiFi AP started at this line of code:
https://github.com/OpenSprinkler/OpenSprinkler-Firmware/blob/master/main.cpp#L463
The otf->loop() function does the house keeping of responding to WiFi web requests. AP needs to be started before that, which is the case with the code.

[polskifacet]

compiles fine, screen doesn’t work. AP mode works, add my ssid etc, then reboots back to ap mode. Seems chip is warmer than with 2.1.9 original working firmware?

[usydow]

I have a few hardware questions?
I have tested a LAN connection.
Since I still had a board with the LAN8720, this was no problem. The drivers are already present by default. Like in the example code:
https://github.com/espressif/arduino-esp32/blob/f1b06d2a74acdef190ac16e83d48ab619f557e73/libraries/Ethernet/examples/ETH_LAN8720/ETH_LAN8720.ino
Runs without problems! (Testcode)
byte OpenSprinkler::start_network() {
lcd_print_line_clear_pgm(PSTR(“Starting…”), 1);
uint16_t httpport = (uint16_t)(iopts[IOPT_HTTPPORT_1]<<8) + (uint16_t)iopts[IOPT_HTTPPORT_0];

#ifdef ENABLE_DEBUG
#if defined(ESP32)
//DEBUG_PRINTLN(F(“SPIFFS dir:”));
//SPIFFS_list_dir();
DEBUG_PRINTLN(F(“Starting network”));
useEth = false;
WiFi.onEvent(WiFiEvent);
ETH.begin(ETH_PHY_ADDR, ETH_PHY_POWER, ETH_PHY_MDC, ETH_PHY_MDIO, ETH_PHY_TYPE, ETH_CLK_MODE);
delay(1000);
#endif //ESP32
#endif

#if defined(ESP8266) || defined(ESP32)

DEBUG_PRINT(“ETH enabled: “);
DEBUG_PRINTLN(useEth);
DEBUG_PRINT(“Wifi mode: “);
DEBUG_PRINTLN(( get_wifi_mode() == WIFI_MODE_STA ) ? F(“STA”) : F(“AP”));
//start_network_sta(“myssid”,”mypassword”);
// FIXME, just for testing
//::start_server_ap();
Since now relatively many GPIOs are needed for the LAN connection I would control the portexpander via I2C. Or does the 74HC595 have advantages?
What is the encoder needed for?

[v1pr]

Sorry for the late reply, did not see the update mails.

@Ray, it seems to me, that after a factory reset the AP is not started, but OTF is in OpenSprinkler::start_network() and this leads to a crash, when OTF want’s to start the server (server.begin) – I’m guessing here – ‘cos the TCP stack is not available. If I start an AP/STA beforhand, than it does not crash.

@polskifacet which LCD are you using?

@usydow: I’ve (hard)disabled LAN support (for now). It’s possible to get it working, but I don’t have any LAN boards now. It does not matter if you use I2C portexpander or an 74HC595 shift-register. I’m using the later on my custom board, since that’s how my friend designed it. On an another install I’ve I2C expanders. Really does not matter. About the encoder: I’m not 100% happy with the 3 button solution, I prefer to use a rotary encoder, but did not had the time to finish the implementation – it’s much more difficult, than I first calculated due to the extensive button logic.

Finally my test setup’s parts arrived, I’ll put the together quickly to speed up the debugging.

[polskifacet]

The original 2.1.9 firmware port works, its a esp32 board with OLED built in. It’s the .96 (SSD1306) screen.

https://randomnerdtutorials.com/esp32-built-in-oled-ssd1306/

[Ray]

@v1pr: as I said, those functions in OpenSprinkler::start_network only create various objects and initialize them, AP does not need to be started at that point. In any case, I’ve never observed ESP8266 crashing due to this. Is this causing ESP32 to crash?

[v1pr]

@Ray: seems so. I was able to track it down to OTF ESP32 server.begin() – that’s where it’s crashes (after factory reset). If I initialize an AP beforehand, all is OK.

[Ray]

OK so maybe the way ESP32 works is different.

[v1pr]

The LCD works for me, but I only hae 1.3″ one, which uses the SH1106 driver. One bug still exists, the LCD turns off after ~10s, when everything is initialized… still chasing that one.

I’ve pushed a new version to git, managed to fix the factory_reset loop, please give it a try (don’t forget to change the LCD type to LCD_SSD1306 in esp32.h ! )

[Ken.238]

I compile the one from git seem like working. Only the buttons and sensors not test yet, I need to locate where the gpio define. Thanks for your hard work.

[Ken.238]

I test the firmware seem like working only those sensors not work or I test wrong gpio. Can you post those define gpio?

[v1pr]

Sure, it’s in esp32.h:

#define E0_PIN_SENSOR1 39 // sensor 1
#define E0_PIN_SENSOR2 33 // sensor 2

If debug is enabled, than you can also check in the output upon bootup.

[polskifacet]

I ended up erasing the flash on my esp32 and then pulled the repo again. Great news, no more boot loop! I can log into web ui and confirmed the pins I have defined work as intended. Only thing that doesn’t work for me is the screen, seems like it loads the right library so not sure. I see one error at the end of this log “[ 17561][E][vfs_api.cpp:105] open(): /littlefs/logs/19521.txt does not exist, no permits for creation”

@polskifacet the error is ok, it’s due to the internal working of LittleFS. About the screen: are you sure, it’s a 0.96″? You can try switching to SH1106. The lib is the same as in the original FW and Ja.Carer’s fw… other thing you can try, is to change the OLED lib’s version in platformio.ini (4.4.0 is the latest ). Cabeling is ok? PIN21 = SDA PIN22 = SCK is the I2C

[polskifacet]

No luck
– updated lib to 4.4.0
– tried SH1106 and SSD1306
– Flashed Ja.Carer’s fw and it works

[v1pr]

That’s interesting… Nothing happens, if you press a button? Or after a factory reset it’s still black? No logo, nothing?
When, you flash back with the old 2.1.9 fw, than you’re using Arduino Ide, right? What is the oled’s library version there? (search for ssd1306 in library manager, should be the ThingPulse one)
