Anyone has idea for this?

I'm using an MTK3339 GPS module with UART1 in pins 16 (RX) & 17 (TX). I can read data coming from the GPS module with uart_read_bytes() on UART1, but I can't get uart_write_bytes() working to send commands to the module (see: https://cdn-shop.adafruit.com/datasheets/PMTK_A11.pdf ). I've tried sendi...

Hi, Recently, I started to look for PHY init data management into ESP32 w.r.t. Calibration process as well. I have looked into make menuconfig configurations and found total 3 configurations for RF Phy Init Data configuration. 1) Default RF Calibration at boot time 2) Customize RF init data using Pa...

Alternatively, replace ESP_INTR_FLAG_IRAM with ESP_INTR_FLAG_DEFAULT when you are registering the interrupt. Then the interrupt will be automatically disabled at times when cache is disabled. You will be able to call non-IRAM functions from ISR in this case. Hi, Thanks for quick reply. I will check...

Hi,

Thanks for quick reply. I will check and let you know result for that.

So, How can I set alarm value in my both ISR calls?

timer_set_alarm_value is not IRAM_ATTR function. Check methods inside ISR in example https://github.com/espressif/esp-idf/blob/7522b5342320d73036a54501b1773889ecd36c05/examples/peripherals/timer_group/main/timer_group_example_main.c Hi, I didn't get your point. We have followed Hardware Timer conce...

Hi All, As we are developing one application on ESP32 and we have used ESP32 2.0 Official Release for SDK base, We are getting Guru Meditation Exception randomly in application while using Hardware Timer. We have used Hardware Timer based on example provided with some our modifications. Please find ...

Hi, I have been working into ESP32 SDK and application since last 6 month and we have found Interrupt Watchdog Timeout issue after storing downloaded firmware into SPI Flash and it has been running into one Task. So, After that I have checked some ESP32 configurations and found one Watchdog Interrup...

Isn't it easier to use the RMT peripheral then? That peripheral is designed to send user-shaped pulse trains with high precision. Hi, I need to check that RMT interface. Here, we have only one wire GPIO pin to update firmware into connected module. Please share example of RMT based interface as per...
