Re: WIFI_MODE_APSTA Sample

I am looking into arduino sample for esp32. There is: #define WiFiMode_t wifi_mode_t #define WIFI_OFF WIFI_MODE_NULL #define WIFI_STA WIFI_MODE_STA #define WIFI_AP WIFI_MODE_AP #define WIFI_AP_STA WIFI_MODE_APSTA So I can assume there is AccessPoint mode Station mode and AcccessPoint and Station mod...

PWM interruts when duty is changed

Hi, I am trying 20kHz pwm on arduino esp32. My source code is https://github.com/zhivko/BleVogaLifter-esp32-DRV8703Q/blob/master/src/Server.ino and the result of changing PWM is seen as gap in pwm. Please see recorded video of pwm signal from above sismple example - PWM is still interrupted: https:/...

Re: ESP32 Minimum Hardware

Schematic for minimal hardware with resistors on gpio0, and EN and buttons would be much appreciated (plan to use it with USB to logical level RX/TX adapter).
Anybody has this schematic?

Re: Loading image via JTAG adapter

Flashing over JTAG would be really neat. Using 2 cables is not fancy ;).
@ESP_Angus: do you see this could be implemented in near future? I think it would help the platform to become mature and allow users to easier catch all this possible nasty bugs thata could happen during devel cycle.

Re: chip reset problem

We know wifi is critical for working - couldn't we somehow dedicate wifi to run on first core and user program on another?
Is rtos mixing first and second core for all task including user tasks and wifi tasks?

Re: wroom32 schematics

Why they mark GPIO11 when it is flash reserved? Ughh... So basically all this SD_ pins fall under same flash operation pins that user could not use since then flash would be useless? SHD/SD2 17 GPIO9, SD_DATA2, SPIHD, HS1_DATA2, U1RXD SWP/SD3 18 GPIO10, SD_DATA3, SPIWP, HS1_DATA3, U1TXD SCS/CMD 19 G...

[SOLVED] wroom32 schematics

Oh that's a shame - I just followed pinout picture and pin11 is indeed shared for flash and gpio... But if gpio could not be used - why put it on this image? https://www.google.si/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwi3__z9wb_QAhWH1xQKHVDxCY0QjRwIBw&url=https%3A%2F%2F...

Re: wroom32 schematics

Another question - I added led to my board to pin no 11.
I uploaded sketch, and I barely see led light instead of bright flashes - When I measured voltage on gpio11 - it shows 1.57V.

So what's wrong with using:

Code: Select all

int ledPin = 11;
in blink example?
