Re: Interfacing Encoder Switch with ESP 32

I had a debouncing circuit already in place, I see some curved rising and falling edge. Let me make it straight by tweaking the R in the RC circuit.

Interfacing Encoder Switch with ESP 32

Hi, I am interfacing ESP32 with an encoder switch and not able to read it properly in both directions. If I limit it to one direction, it works almost fine. Here is the configuration: #define ENC_DATA 25 #define ENC_CLK 33 #define ENTER 26 inside main before while(1): gpio_set_direction(ENTER, GPIO_...

Re: ESP32 - GPIO speed lower than expected

I was able to get 10Mhz @ESP32 working at 240Mhz with following instructions:

You can save on bit shifting the bit 1<<(2)

GPIO.out_w1ts = 0x04; // GPIO2 HIGH
GPIO.out_w1tc = 0x04; // GPIO2 LOW

My code was compiled still in debug mode.

Not sure, if there is a way to increase the speed a bit more?
