Does anyone know the correct way to calculate PCLK frequency and FPS from the OV5640 configuration parameters?

I am trying to verify whether the VCO, SYSCLK, and PCLK frequencies are within valid ranges when using a 24 MHz XCLK.

I am implementing a calculator:

Thanks for providing the camera example.

Just as an additional note: there appears to be a bug in the SDK related to the sampling edge.

In the camera example, config->pclk_sample_edge is never initialized, so it effectively defaults to PARLIO_SAMPLE_EDGE_NEG (0). As a result, parlio_rx_soft ...

I connected simple power metter to ESP32 devkit and found that peak level in Long Range mode is twice smaller then in 802.11b mode.
Why? Does LR mode use multiple subcarriers and thus have to lower peak level? Any details on LR mode modulation?

I am sending ESP-NOW packets between two ESP32 boards.
I also setup promiscuous callback to see RSSI. In wifi_promiscuous_pkt_t ppkt->rx_ctrl.rate I can see PHY rate of each packet.

I am not calling esp_wifi_internal_set_fix_rate().
In normal mode, I see ppkt->rx_ctrl.rate = 0 which I suppose is ...
