"gpio isr service already installed"的含义及解决方案 1. 含义 "gpio isr service already installed"这一消息通常表示在尝试安装或注册一个GPIO(通用输入输出)中断服务例程(ISR,Interrupt Service Routine)时,发现该服务例程已经被安装或注册过了。在嵌入式系统或Linux内核编程中,每个GPIO中断通常只能有一个服务例程...
Re: Error:GPIO isr service already installed PostbyPiyush»Tue Sep 21, 2021 1:02 pm Hi Nirmesh, I tried your new code from github and compiled it with idf 4.2.1. I only did this minor change for it to compile with latest esp-rainmaker: ...
I assume in a more complex program that has other libraries and code already in place, the gpio_install_isr_service(ESP_INTR_FLAG_DEFAULT); call may have been made by some code outside my control. Is there any harm calling it again, in my code? If so, how to check if the call ha...
gpio_install_isr_service(ESP_INTR_FLAG_IRAM); The camera starts up, but with warnings: E (1855) gpio: gpio_install_isr_service(438): GPIO isr service already installed W (1856) camera: gpio_install_isr_service already installed How to solve this problem?
In that last log, I haven't had a chance to set any ISRs as it hasn't yet returned from gpio_install_isr_service (note the absence of any "Installed the ISR Service ..." log). I am calling gpio_isr_handler_add, but a long time after gpio_install_isr_service, so as you can ...

If this function is used, the ISR service provides a global GPIO ISR and individual pin handlers are registered via the gpio_isr_handler_add() function. Return ESP_OK Success ESP_ERR_NO_MEM No memory to install this service ESP_ERR_INVALID_STATE ISR service already installed....
I have ESP32 with ov2645 and OLED display (No PSRAM). I am using esp-idf v4.1.0. The code compiles successfully but when run on the board I get an error when initializing the ov2645 camera. The error occurs when gpio_install_isr_service(ESP_INTR_FLAG_LEVEL1 | ESP_INTR_FLAG_IRAM...
