I believe that the internal pull-ups *can* be activated by code but I don't think by default are they activated. In your case it sounded like high was what caused the sound generator because:!===> without a signal from the processor they "float" and to the sound driver they appear high. So, the sol...

Take a look at this: https://www.arduino.cc/en/Tutorial/DigitalPins Yes, it applies beyond Arduino. Tom Meyers Ohh I see... thanks you for answer... I only worked with microchip... so I need pullups mmmm the ESP32 has internal pullup? the same problem I have with the UARTs, I have one module connec...

Hi, this is my first time for work with SoC and freeRTOS. I need set 3 IO to 0 Level just in void app(), why the micro take many time for put this IO to 0 once time turn on. Take 2 to 3 sec for runing the software, this is bad cause I have conect one buzz to IO output, and to start is in level 1. af...

Hi, I need know how i do run the Interruption UART1 and 2 I did this and the uart1 working very good, my question is how i do for run the uart2 http://zerothelement21.blogspot.com/2018/05/esp32-uart-interrupt-handling.html static intr_handle_t handle_console; // UART0 static intr_handle_t UART1_NFC;...

Hi, I have this: void uart1_task(void *pvParameters){ char character; char tem; //struct cmdBuf cmdBuffer; keyboard_command_t keyboardCmd; //Install UART driver, and get the queue. esp_err_t ret = ESP_OK; const uart_config_t uart_config = { .baud_rate = 9600, .data_bits = UART_DATA_8_BITS, .parity =...

I see... I can not use that pins... so the UART1 can not used? You can use the GPIO Matrix to remap UART1 to any other GPIOs which are unused. I cut all wires to 6-11 and now show this Looks like it's mostly working? thanks , now work fine and let me flashing... but its rare.. I have presed reset a...

Thanks you for your answer.... I saw the PIN20 (CLK) i used for ADC... so I did cut the wire and now show this rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0x00 clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:2 load:0x3ff...

Hi,I have the same problem... What I have bad? rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) flash read err, 1000 ets_main.c 371 I tried put resistor 5K to GND on IO2 but same Not let flashing... I used a normal USB/TTL wire http://subirimagen.me/uploads/20181031195203.PNG LD build/hel...

Thanks you... I does it

Component config > FreeRTOS
There is an entry called "Run FreeRTOS only on first core".

viewtopic.php?t=802

now its running

Please say me where I do it? make menuconfig or in code?
