D1 mini only can boot/upload with all sensers disabled

[Takzy]

I have a question.

Somebody asked me to make a combination of an 8 channel relay, a 433 mhz transmitter and a D1 mini to let them control by website. Home automation.

Therefor i need all digital outputs D0 - D8, and i use D3 for the transmitter. The others (D0-D8 exccept D3) are all connected to the relay.

I have tested about five different D1's Mini, but all of them give the same behaviour:

- I cannot upload programs with the transmitter/relays attached (both of them must be disabled)
- I cannot use Serial.print and the plotter/monitor when the relays/transmitter are connected top the D1.
- I cannot boot the D1 mini with relays/transmitter attached. It only turns on the relay on D8.

A simple solution is to disconnect all attachments at startup. But it is no good solution: after a power-interrupt, you won't have to open the box and disconnect wires before you van use it again. And, after a power-distortion at night you won't something to start connected to the relay at D8.

Program:

Code: Select all

#include <ESP8266WiFi.h>
#include <RCSwitch.h>
 
const char* ssid = "ADD HERE YOUR SSD OF YOUR NETWORK";       // <<==This is your wifi SSID
const char* password = "ADD HERE THE PASSORD OF YOUR NERWORK";// <<==This is the password which belongs to the network with the SSID above
const String websitename = "Takzys control centre ";          // <<==This will be the title of the generated website

RCSwitch mySwitch = RCSwitch();

//Translation table for arduino clones (and D1's) with their ARDUINO port number used for the relays

int pinTranslator[9] = {0, 16, 5, 4, 2, 14, 12, 13, 15};

//Device names are below in the (client.print) section where the HTML is generated. 
//The exact location can be found by searching for: "var desc = [" without quotes.
//This section matches the devices with their destination. So device 1 can be used with a relay, 
//or with a code for 433 mhz.
//Destinations: 1 - 8 = relay number 1 - 8, 11 - 18 = wireless device 1 - 8, 99 = not in use)

Hello,

some hints for going on (Even if this is a forum for ESPEasy firmware, not for ESP8266 in general ).
The configuration you use will possibly run into troubles.

Some GPIO's need a specific setting, otherwise the ESP will not boot.
They are used to set the boot mode to "Boot from Flash" (starting from internal flash memory),
"Flashmode" (firmware flashing) and "SD-Card" (Starting software from external SD.)

The usual start mode for ESPEasy is "Boot from Flash". Therefore some GPIO have to be set:
D3/GPIO0 = 1 (high)
D4/GPIO2 = 1 (high)
D8/GPIO15 = 0 (low)

If your relay board or 433MHz device pulls one of these to a wrong settings the ESP will not boot.
For example, if your 433-transmitter has a pullup resistor on the data input, the D3 / GPIO0 will be pulled up and the ESP will boot into "Flashmode".

On the WeMOS the GPIO 9 and 10 are not broken out - they should be avoided anyways, they are used for SPI/SD-Card and well known for troubles.

I strongly recommend to use a PCF8574 GPIO multiplexer. It uses I²C (Usually D1 / D2 - GPIO 4 / 5 on the WeMos), it is easy to handle and
several PCF8574 can be connected together, giving a lot of GPIO pins.
The http commands to switch on/off are similiar to standard GPIO's - just "pcfgpio" instead of "gpio". I've made a 8ch relay driver this way, it works.

For Input you may set up one task per input pin for a PCF8574.

You may use one PCF8754 for driving your relays and use D5 - D7 (GPIO12,13,14) as additional direct input if necessary for what reason ever.

Shardan,

Excuse me, I see I took the wrong place for this question.

Besides that I want to thank you for your answer, it gives me enough ideas for a possible way to go. (The port extenders are ordered!)

Some tests show that disabling D1, D2 and D8 let it boot, and make it possible to upload programs again! I think I've used the wrong search terms for this problem, I've been looking for an answer for about two weeks now.

May i thank you?
