compile error about sonoff-tasmota HOT 40 CLOSED

Let me recheck. Based in the frequent changes, this cold happen

from sonoff-tasmota.

idk if the full log helps but here it is:

Hi did you compile with or without the pcf module. What have you defined in you configuration.

from sonoff-tasmota.

@stefanbode i only defined my wifi, mqtt and with this :
#define USE_I2C
#define USE_BH1750
#define USE_PCF8574
//#define USE_ADS1115
#define USE_BMP
//#define USE_HTU
//#define USE_SHT

even when i compile without any changes except pcf8574 enabled it gives the error.

from sonoff-tasmota.

If you use pcf you must enable i2c. I always use this configuration. Will check tomorrow. Looks like a side effect.

from sonoff-tasmota.

@stefanbode how can i fix this issue ?

from sonoff-tasmota.

It works for me. I assume i2c is not enabled

from sonoff-tasmota.

@stefanbode
it is enabled if i set it in user config
#define USE_I2C
there are no // in front of it
or do i need to configure it in another file?

Sonoff-Tasmota-stefan_patch1 (5.12.0c)
is this the right version to get the pcf8574 working ?

from sonoff-tasmota.

Any change should be made in the user—configuration—override file. The user configuration normally should not be changed. This is the intend. The version you‘re using is correct. I made some changes yesterday and have some time to play today. I will double check where this comes from. Normally when you get this message at the end the use_pcf... is NOT set. This is the only reason, that the variable is not included during compile.

from sonoff-tasmota.

So, I double checked that the compile and the device are running with the current version. I changed to include the PCF now in the xdrv startup procedure, which makes it more in sync with the other modules. Anyhow I still have no clear idea why it did not work at your side. Can you double check that you have the PCF ino file in your source folder. It is now named: xdrv_20_pcf8574.ino

from sonoff-tasmota.

@stefanbode
i can't find the "xdrv_20_pcf8574.ino"file in the source folder and i also cannot seem to find it onto your fork. :-/

from sonoff-tasmota.

missed a sync with the commit. my fault. fixed

from sonoff-tasmota.

ok now it compiles sucsesfully but cant seem to get I2C to working and pcf8574 is not under configuration.

Please correct the i2c section. you undef the variable. This is the reason your command is not working. Comment out the 3 lines and put #define USE_I2C

from sonoff-tasmota.

same result

from sonoff-tasmota.

have you defined the I2C pins in the COnfiguration? The SDA and SCL pin? There is a check for I2C that the scan for sure can only run if these pins are assigned.

from sonoff-tasmota.

i did that. i tested this with another board and now this is working.
how do i configure my gpio pins of the pcf8574?
the command gpio wont show any pcf8574 gpio pins
and i have no menu where i can configure them

from sonoff-tasmota.

if you have defined SDA and SCL pin and the i2scan is showing your board there is an additional Option in the webserver in configuration to define input / output pins of the pcf

from sonoff-tasmota.

i have no extra options in there...

from sonoff-tasmota.

also connected an bh1750 sensor and it gives two readings:

BH1750 Illuminance 543 lx (correct)
BH1750 Illuminance 1073676336 lx (not correct)

from sonoff-tasmota.

Please report this to arenst in the original code. This sensor is not maintained by me.

from sonoff-tasmota.

ok and how about the pcf8574 options i have no extra menu in configuration ?

from sonoff-tasmota.

Hi @tarbax , I invested some time this evening to clean up and sync to the main branch. Indeed there was a problem with the PCF8574 menus. TO get it working first define SDA and SCL and connect the board correctly. You should see in the seriallog messages that one PCF board was found. Then in the CONFIGURATION submenue there is a PCF menu. This was also working on the last version. But when you click on it you got an empty page. I have fixed that now and everything is working again.

from sonoff-tasmota.

Thanks really! i will try it out this night.

from sonoff-tasmota.

hmmmm not sure what is happening:

23:31:35 MQT: hm/status/sonoff/RESULT = {"I2CScan":"Device(s) found at 0x26"}

It is wired up correctly but wont detect it, tried 2 different pcf8574 and 2 wemos d1 mini pro's
:-/

from sonoff-tasmota.

In your configuration is something wrong because it cannot connect to the board. I can see this in the log file

00:00:09 RSLT: pcf8574 0 boards

Maybe SCL and SDA mixed.

from sonoff-tasmota.

i already tried that, also tried on other gpio pins :-/
i am guessing that i received 2 bad pcf8574 boards. but isn't that highly unlikely?

from sonoff-tasmota.

Could it be that the module is 5V only?

from sonoff-tasmota.

i also already tried the whole range of input voltage.

from sonoff-tasmota.

i ordered two more pcf8574 to be sure mine are broken or not.

from sonoff-tasmota.

@stefanbode
i just confirmed that my modules are working.
when i connect only 1 pcf8574 module i get these reading on the webgui:

Analog0 1
BH1750 Illuminance 1073676304 lx
CHIRP Moisture 0.0%
CHIRP Temperature 128.5°C

from sonoff-tasmota.

Please take a look above. If a Bord is detected on the I2C Bus you must see this in the log

Can you check on your Board wich I2C adddress is used? Maybe just remove a jumper. I have tested it with 8 boards in parallel. The starting address is hardcore in the Pcf ino file. The detect is a simple write check on the bus. If this does not work there is a hardware issue. Can you check, if there are 10k pull-up or Pulldown resistors required for the I2C?

from sonoff-tasmota.

Here is a seriallog how it should look like during startup with Loglevel 5 and above:

00:00:00 I2C: PFC8574 found at 0x38
00:00:00 RSLT: pcf8574 1 boards
00:00:00 RSLT: I2C Config: 255
00:00:00 RSLT: I2C shift i 0: 1. Powerstate: 0, devices_present: 0
00:00:00 RSLT: I2C shift i 1: 1. Powerstate: 0, devices_present: 1
00:00:00 RSLT: I2C shift i 2: 1. Powerstate: 0, devices_present: 2
00:00:00 RSLT: I2C shift i 3: 1. Powerstate: 0, devices_present: 3

00:00:00 RSLT: I2C shift i 4: 1. Powerstate: 0, devices_present: 4
00:00:00 RSLT: I2C shift i 5: 1. Powerstate: 0, devices_present: 5
00:00:00 RSLT: I2C shift i 6: 1. Powerstate: 0, devices_present: 6
00:00:00 RSLT: I2C shift i 7: 1. Powerstate: 0, devices_present: 7
00:00:00 RSLT: Final max devices: 8, PCF8574 devices 8

You can see that the device reports on address x38. This is the first possible address when ALL three jumpers are set to the right side. SLC and SDA are D1 and D2 on a Wemos board.

Please check this website for wireing the native ESP: at least SDA must have a 3.3K pull-up
http://www.gunook.com/wie-benutzt-man-die-esp8266-01-stifte/

from sonoff-tasmota.

@stefanbode so i can only detect the first pcf if it has adress x38 ?
i can only reach as high as x27 with my boards

from sonoff-tasmota.

Ok in this case just change the start address permanent in the pcf *.ino file. My devices all start at x38 an above. I can’t test on all 127 addresses because other I2C devices will also send an ok. Therefore normally the devices have no overlapping IDs

from sonoff-tasmota.

@stefanbode thanks! now it is detected and i have the option in my configuration menu. but there is still the blank page bug

from sonoff-tasmota.

The was in older versions a bug. The current one at least with chrome and on Apple devices run fine . These are my two testing devices.

from sonoff-tasmota.

i have osx and tried safari and chrome. latest version of your master. still blank page
