PinViewer crash

[JanuNoo]

Hello, I have tried to simulate gpio input events with ESP32 DevKitC board and when I toggled the pin I wanted to test with PinViewer it just crashed. I did the following:

//define queue gpio_evt_queue = xQueueCreate(10, sizeof(uint32_t)); //start gpio task xTaskCreate(gpio_task, "gpio_task", 2048, NULL, 10, NULL);

//set pin for input int INPUT_PIN =18; //defined GPIO 18 for input //zero-initialize the config structure. gpio_config_t io_conf = {}; //interrupt of rising edge io_conf.intr_type = GPIO_INTR_POSEDGE; uint64_t pin_bit_mask=((1ULL<<INPUT_PIN)); io_conf.pin_bit_mask = pin_bit_mask; //set as input mode io_conf.mode = GPIO_MODE_INPUT; //enable pull-up mode io_conf.pull_up_en = 1; gpio_config(&io_conf);

//add pin listener gpio_install_isr_service(0); gpio_isr_handler_add(INPUT_PIN, gpio_isr_handler, (void*) INPUT_PIN);

static void IRAM_ATTR gpio_isr_handler(void* arg) { uint32_t gpio_num = (uint32_t) arg; xQueueSendFromISR(gpio_evt_queue, &gpio_num, NULL); }

static void gpio_task(void* arg) { uint32_t io_num; for(;;) { if(xQueueReceive(gpio_evt_queue, &io_num, portMAX_DELAY)) { ESP_LOGI(TAG, "GPIO[%"PRIu32"] intr, val: %d\n", io_num, gpio_get_level(io_num)); } } }

From the error log file I got:

Any ideas of what the problem is? Thanks

Hi @JanuNoo ,

thanks for reporting the problem. The problem occurs because the interface used by the pinviewer accesses the simulator in a different thread than the one running qemu-esp32. As soon as I have time I will try to solve the problem. Meanwhile, use a switch or pushbutton in the spare parts window to test your program.

Hi, I tested again using push buttons as you said and I confirm that works indeed. Thanks

Hi @JanuNoo,

the problem with PinViewer as fixed in commit a646624 . Try the latest build version with the fix .

Works, thanks.
