Answers checklist.

[X] I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
[X] I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
[X] I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

I want to read analog data from the sensor, what history should I use to ensure that other features work?

Lzw655 commented 7 months ago

Hi @isthaison, you can use pins as shown below to read analog data. Please check the "NOTE" to know their limitations.

isthaison commented 7 months ago

If so, then in this situation only IO4 pin can be used. no can't use S3's SPI and LED, right?, or is there another way

Lzw655 commented 7 months ago

Yes.

isthaison commented 5 months ago

@Lzw655
Can we read analog with Pin?

Lzw655 commented 5 months ago

Hi @isthaison,

Sorry, the TCA9554 chip can only read digital level 0/1.

isthaison commented 5 months ago

If so, then only IO4 and IO19 can be used on this board. but it is used for LED and USB, which is quite inconvenient. If there is an upgrade board, we can always design at least 2 pins for ADC and 2 Digital pins. This will make it easier for developers to develop their own integrations

Lzw655 commented 5 months ago

You are right. This ESP-S3 development board has a shortage of IO pins due to the integration of RGB screen, audio input, and output functions. The upcoming ESP-P4 development board will provide ample IO pins.

isthaison commented 5 months ago

When will the ESP-P4 development board be released? Because I am preparing to deploy the project, in large quantities

Lzw655 commented 5 months ago

I'm sorry, but there is currently no exact time available.

Edited: About 1-2 months later.

isthaison commented 5 months ago

Somehow, could you sell me one in advance so I can research it first :D

Lzw655 commented 5 months ago

I'm sorry for not getting back to you sooner. You can contact Espressif's business team to get a sample.

isthaison commented 5 months ago

Can I ask for design files (dfx, etc). some format that can be imported into design. instead of the dpf file that the document provides. I am designing an expansion pcb part to connect the expansion pin

isthaison commented 5 months ago

If so, I have to redraw. but it will have the risk of errors between related departments
