Re: PCA9685 connecting problem

I second that! Maybe it would be the best to reduce the ComboBox to the four entries and make 0x14 as default. Also it would help to explain within the drop down or next to it whats the result of each option.

Re: PCA9685 connecting problem

Good question. Here is the datasheet: https://cdn-shop.adafruit.com/datasheets/PCA9685.pdf On page 16 you can find the description of the Mode 2 register. The difference between 0x10 (Binary 00010000) and 0x14 (Binary 00010100) seems to be the second bit (starting at bit 0) and this is: 0 The 16 LED...

Re: PCA9685 connecting problem

Testes both, an what should I say, it was the 0x14 mode. The older ESP Mega image doesn't support setting the mode. The newer ones (I tried December 2018) let you specify the mode while creating a device. So first you have to ad the device, specify the address (0x40) and then change the mode to 0x14...

Re: PCA9685 connecting problem

I just flashed the older Version ESP_Easy_mega-20180804_normal_ESP8266_4096.bin on my NodeMCU Lolin V3 Board. After sending the command, I get the HTTP result (see image attached). But also no PWM at the PCA9685 pins.

Re: PCA9685 connecting problem

Hi, I tried that already, but 0...16 seems to be the correct ones. I also flashed an older EspEasy Mega Version from August 2018 and made a factory reset. Unfortunately still the same, no PWM at the PCA9685 Pins. :(

Re: PCA9685 connecting problem

Nobody? I've purchased a second PCA9685, but unfortunatley the same problem with the second one too. Maybe someone will find a mistake in the construction of my circuit (see image attached).

Greetings, Hannes

PCA9685 connecting problem

Hi, I am currnetly trying to connect an PCA9685 to an NodeMCU (ESP8266) Board. On the ESP is running ESP Easy Mega from December. So far I've connected GND between the ESP and PCA9685, 3,3V to VCC and also GPIO4 to SDA and GPIO5 to SCL of the PCA9685. I've left the additional Power-Connections at th...
