Zigbee: Why does my Temperature Sensor not obey my commands?

Hi, I am trying to make temperature sensors work on ESP32S3 + ESP32-C6. The sensor is a TUYA Zigbee The manufacturer gives some information here . After binding the sensor to my network, I am telling it to occasionally report with this command: esp_zb_zcl_config_report_cmd_t report_cmd; uint8_t repo...

Re: Calling gptimer_start() from ISR crashes. Why?

I solved it by using the High Resolution timer like: const esp_timer_create_args_t oneshot_timer_args = { .callback = &oneshot_timer_callback, .name = "one-shot" }; ESP_ERROR_CHECK(esp_timer_create(&oneshot_timer_args, &oneshot_timer)); esp_timer_start_once(oneshot_timer, 10000); static void oneshot...

Re: Calling gptimer_start() from ISR crashes. Why?

Thank you! It still doesn't work tho :) I changed my ISR. And also just used the global var. Screenshot 2023-09-14 at 8.29.36 am.png Then I moved the ISR out of the IRAM. No avail. Maybe my interrupts are coming in too fast at 10HZ? Perhaps something to do with stack rise of interrupts? Any other id...

Calling gptimer_start() from ISR crashes. Why?

Hello, I just spent 4 hrs trying to figure this out, but I don't know why my code crashes. Could someone please have a look? I have a Pulsecounter running, reading pulses from GPIO21. Also on GPIO21 is an Interrupt (positive edge). The interrupt handler is supposed to start a timer. However, I canno...

Zigbee with ESP32-S3 & ESP32-C6

Hello, I understand that for Zigbee, we need Wifi 802.15.4. I would combine my ESP32-S3 with an ESP32-C6. However, the documentation only ever mentions the ESP32-H2 for Zigbee. But this modul is not yet available. Can use the C6 instead of the H2? 405F0636-20E6-44A1-A177-4714937FB4FD.jpeg Thank you

How can I terminate FreeRTOS tasks and get the memory back?

Hello, I am running 2 tasks on my ESP32-S3 - Graphics Task - Sensor Task But when I start WIFI and add an Over-the-air update Task, the system runs out of memory. I get strange errors like: I (13590) esp_https_ota: Starting OTA... I (13590) esp_https_ota: Writing to partition subtype 16 at offset 0x...

Octal Flash option selected, but EFUSE not configured!

Hello,

when I chose Flash Mode --> OPI 80MHZ, the ESP32-S3 N8R8 reboots and I throws this error message:
Octal Flash option selected, but EFUSE not configured!

Can somebody tell me what I need to configure on the EFUSE to get the Octal speed PSRAM working?


Thanks!

Re: ESP32 + TFT not working - Screen Blank - Help!

The screen backlight should glow up as soon as you connect 3.3 V and ground.

Since its an LED, you need to connect it through a resistor (100 OHM would work).

It seems there is no resistor now. So maybe the high current draw makes the ESP32 turn off and thats why it doesn't work.

is there a way to use access the vsync event

Hi,

on ISP IDF there is a function esp_lcd_rgb_panel_register_event_callbacks().

It can be used to define .on_vsync and make displays work better.

But it not available on Arduino.

Is there a way that I can get this function into Arduino?

Thanks

Re: ESP32 + TFT not working - Screen Blank - Help!

Does at least the background light turn on?
