shifting to the Master’s actual latch edge. In this case, if the GPIO matrix is bypassed, the hold time for data sampling is 68.75 ns and no longer a half of an SPI clock cycle. If the GPIO matrix is used, the hold time will increase to 93.75 ns. The Host ...
5. ADC On the ESP32 ADC functionality is available on Pins 32-39. Note that, when using the default configuration, input voltages on the ADC pin must be between 0.0v and 1.0v (anything above 1.0v will just read as 4095). Attenuation must be applied in order to increase this usable vo...
flash/esp: Increase hash calculation algorithm timeout to 30 sec. If the targets don't yet have clock boost functionality, reading flash through the cache takes longer than accessing the flash directly—likely due to the cache_suspend, cache_resume, and cache_invalidation functions. As a result...

Someone said there could be a 96000 bytes limit even though there is lots of RAM left. Is there a way to modify the Arduino ESP32 core to increase the heap size by 32K? I tried making a local array inside of loop() instead of global. It compiles if I do this but the processor ...
The board is fitted with a level translator which may limit the maximum clock rate, so drop the SPI clock speed. Try 4MHz and increase if that works Use and configure a GPIO for the RST pin (the board may not be getting a reset at the right time if it is not connected or tied to...
increase or decrease, which is useful for the LED RGB color-gradient generator. 4.1.17 Serial Peripheral Interface (SPI) ESP32 features three SPIs (SPI, HSPI and VSPI) in slave and master modes in 1-line full-duplex and 1/2/4-line half-duplex communication modes. These SPIs also suppor...
Moreover, each channel automatically supports step-by-step duty increase or decrease, which is useful for the LED RGB color-gradient generator. For more information, please refer to Chapter LED PWM Controller (LEDC) in ESP32 Technical Reference Manual. 4.1.17 Serial Peripheral Interface (SPI) ...
You can increase PWM frequency up to an extent, but remember electronics is a weighing game of trade-offs. While your MPPT buck can handle more power with a higher PWM frequency, the switching losses would also increase up to some point. Also there's a limit between the PWM Reso & Freq...
