Thx.

The only one that explicitly mentions rev.1 seems to be the wrover board.
Sadly, this doesn't fit my project very well, I plan on using a touch screen display.

Hi all

I'm wondering if there's any breadboard compatible rev.1 ("new silicon") dev boards out in the wild right now.
If there is, I'd be happy to know a source.

You could do a quick check directly in the ISR if the last event has been too recent, and ignore the new interrrupt in this case.

Hi Jesse,

what resolution do you need for your pulse width measurement?

You sent the address of gpio_num instead of it's value to the event queue.

I'm pretty sure that's not what you wanted

Have you tried setting the upload baud rate to 115200?

There's an arduino core available for the esp32, if you want to use the arduino libraries.

Things are slowly starting to improve in the I2C department. While trying to figure out how to make long (>32 bytes) transfers work, I found there's a nicer way to send long frames. I2_CMD_WRITE will actually take a byte_num paramater larger than 32 in FIFO mode. All you have to do is keep the FIFO ...

Hi Alizame, as far as I understand the w1ts/w1tc registers, you don't have to read them out to set/reset GPIO bits. Try this version: void toggle(void *pvParameter) { printf("toggle called.\n"); portDISABLE_INTERRUPTS(); while (1) { GPIO.out_w1ts = (1 << GPIO_NUM_23); __asm__ __volatile__("nop;nop;n...

I'll try to update my arduino installation over the weekend. Guess I'm already up to date w.r.t the I2C part right now though. My changes didn't make the error rate any worse or better, I'm back at the fast version. There might be some EMI issues with my setup. The wiring is rather messy and spans 2...
