Hi Martin,

Thank you very much for your help.
Compilation of the program is already working.
Unfortunately the MFRC522 component is not working and I don't know why yet.

Hello,

I would like to ask for a little help.
I want to use the MFRC522 component with the ESP32 MCU, but I get a compilation error. I tried to change the component hardware settings in the Properties window, but the situation did not change.

I found a solution: If I enable the CS pin and enable the CS pin in Toggle mode, the hardware SPI works. Hooray! So I have to use Chip Select pin to make it work. An observation: If I disable CS Toggle mode, the display no longer works with the hardware SPI peripheral. In this case, the MOSI, RES, D...

Hi Martin, WOW! I would not have thought of this solution, but the compilation of the program worked after implementing your suggestion. :D Thank you very much for your help over the weekend. Now we just need to find out why the SPI interface of the display only works in software mode. :| Do you hav...

Hello, I am using ESP32 WROOM 32 version NODE-MCU. I want to connect a ST7789V display module to it. Unfortunately, I get error messages while compiling the program. I have attached the messages of the first program translation (testST7789.msg1) and the messages of later translations (testST7789.msg...

Hi Ben,

Super.
I tried it with esp32 MCU and SSD1306 display.
I have attached the program in which 3 VL53L0X sensors work on the same I2C bus. It works very well.
Thank you very much.

Hello Ben, Thank you for your suggestion. I was not familiar with this circuit before. I thought of a similar solution, with 2 pieces 4051 analog multiplexers, until I found examples of re-addressing on the Internet. The VL53L0X sensors do have a fixed I2C address, but this can be changed after powe...

Hello, I would like to ask for a little help. I want to use 5 VL53L0X sensors on one I2C line. Can this be solved somehow with the current component macro? If not, would you modify it so that the sensors are individually addressable? It would also be nice if the modified version did not have the XSH...

Thank you very much. It works!

That's right.
There is only a problem with channel 3.
But I don't think it's a chip bug because I get an error message from the compiler about references to undeclared variables.
