我们需要连续读取I2C的ADC模块20次,以获得ADC的稳定值。 我们已经为其创建了一个任务,但是代码停止在几分钟内停止工作,显示以下错误。 E(1925655)task_wdt:

ESP32/freertos停止调度程序在MAIN的开头 - 然后启动任务并重新启动调度程序
在ESP32上的初始序列中,我有几个在初始化期间创建的任务。 现在,我注意到我在初始序列的初始运行期间添加的那些任务。 实际上,我不明白为什么在调用主函数之前启动调度程序。从第一视图上没有意义。 我会怀疑序列是:
spiffs_create_partition_image(storage ../data FLASH_IN_PROJECT) # Crie a imagem do sistema de arquivos SPIFFS para a partição 'www' spiffs_create_partition_image(spiffs ../site/dist FLASH_IN_PROJECT) # Ajuste a configuração do SPIFFS para permitir nomes de arquivos mais longos set(SPIFFS_OBJ_NAME_LEN 64)
我正在与ESP32-VROOM-32U一起使用QTR-8RC传感器阵列时遇到问题。尽管遵循设置和校准程序,但传感器似乎无法正常运行。以下是我的设置和观察的详细信息:
