Add multiple Grove TB6612FNG drivers #2411

Closed simonyel closed 11 months ago

simonyel commented 11 months ago

Describe the problem you have/What new integration you would like o Would love to ability to configure multiple instances of the driver boards

Please describe your use case for this integration and alternatives you've tried: I am making a chemical dispenser for my aquarium and need the ability to drive 4 pumps. To do this I would need two Grove TB6612FNG drivers. Currently, I don't see an option to configure multiples.

I will have a look :) I suppose you managed to change the address of each one, right?

simonyel commented 11 months ago

Does the same address matter when the controllers are on different buses?

Usually you would use the same i2c bus but with a different address. I am not sure the esp has two different i2c controllers and if that the case, I suppose you could setup at the moment without doing any changes.

simonyel commented 11 months ago

I'll change the address if it comes to that. Would that make the code change easier for you?

Right , what it can be done is :

void set_i2c_addr(uint8_t addr);

I can expose this as action and you would need to run the system once and trigger the action to change the address, you can have two on the same bus.

I can see here in the example of setup a new motor, you just going to copy and paste the block , change the address and id. https://esphome.io/components/grove_tb6612fng.html

simonyel commented 11 months ago

I got the address changed for my second driver via Arduino IDE. Now the driverA is at 0x14, and driverB is at 0x15. What's next?

max246 commented 11 months ago

Please take this as assumption since I dont have two motors board:

I would guess you will have to do something like 

grove_tb6612fng:
    id: test_motor_a
    name: motor_outside
    address: 0x14

grove_tb6612fng:
    id: test_motor_b
    name: motor_outside
    address: 0x15

then when you control the motor you use the ID to identify which motor you want to control.

simonyel commented 11 months ago

You can't have duplicate grove_tb6612fng: keys, nor can I nest a list of them under a single entry.

You can't have duplicate grove_tb6612fng: keys, nor can I nest a list of them under a single entry.

For instance. I can't do:

grove_tb6612fng:
  - id: driverA
    name: "Driver A"
    address: 0x14   
  - id: driverB
    name: "Driver B"  
    address: 0x15

or 

grove_tb6612fng:
    id: test_motor_a
    address: 0x14

grove_tb6612fng:
    id: test_motor_b
    address: 0x15
simonyel commented 11 months ago

Any thoughts?

max246 commented 11 months ago

Sorry, got busy with work....

I talked to jess and I just need to add an extra parameter in the code to allow multi blocks.

I will make the change over the weekend, you might need to test my PR if you can

simonyel commented 11 months ago

I will gladly test and report back.

ok done it.

I have updated the doc and tested the code, it works.

Check the doc PR to understand how to setup a multi conf

simonyel commented 11 months ago

I tested the github://pr#5492, and it works as expected. I have two driver boards and 4 DC motors\peri-pumps. I was able to address and execute commands on each device. Start > Break >Stop.
