How to use ESP32 pin as clock output? #14036
-
Hi. I want to use ESP32-S3 with SX1509 to control multiple fans using PWM. Unfortunately, it has a frequency of 2MHz, which can be reduced by using a divider using this formula - 2MHz / (2^(divider - 1). Thus, i can't get 25kHz used by fans. |

You can easily use PWM for that purpose. I just verified that at an ESP32-S3 with 8 Pins at exactly 25kHz and different duty cycles. |
