worked it out, silly mistake

I was setting the timers freq_hz with an integer when it needed uint32_t, not sure how it worked in my last project but it seems to be working now

Hi All
I've been trying to configure PWM on GPIO 5 and 17 (used esp-idf) and while I can get the duty cycle to be set correctly the frequency does not match the value set in the ledc_timer_config_t object. For whatever reason, the period is set to 3.6seconds (rather than a frequency of 25kHz as set ...

This might do the trick

void gpio_deep_sleep_hold_en(void)
Enable all digital gpio pad hold function during Deep-sleep.

When the chip is in Deep-sleep mode, all digital gpio will hold the state before ...

I have been able to solve the problem myself.

If i instatiated the TS7735 object using the default hardware SPI bus

Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);

rather then the bit banged SPI

Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST ...

Can you describe the circuit you are using a bit more, are you using a pull up resistor on the cathode of the LEDs?
Are you sinking the LED current through the GPIO Pins?
Any chance you have a scope and can measure the voltage of the GPIO durring the reset where the flash happens?
I'm not sure what ...

Hello All
I’m using the SPI bus (VSPI) to communicate with an AD9833 chip and a TS7735 LCD display (via the arduino SPI lib), I have been able to communicate with each individually and I have also been able to communicate with the TS7735 and then the AD9833. However, I can’t communicate with the ...
