Re: 求助 ESP32 如何配置 CAN 双滤波器模式 ?

根据双模式的为将两个 ID 值写到 acceptance_code 里。如果 Filter 1 需要监测包的 Data Byte 1,必须将 Data Byte 1 值也写到 acceptance_code 里,否则要用 acceptance_mask 作为位掩码掩盖 Data Byte 1 部分。

Re: CAN vs OTA: interrupt watchdog timeouts despite delay in OTA and IRAM_ATTR in CAN

@jcsbanks I think the first thing to do is to determine whether this is an actual deadlock or a legitimate interrupt watchdog timeout. It's possible that the duration of the the flash operation in addition to handling the CAN interrupt exceeds the interrupt watchdog timeout duration. Try increasing ...

Re: 求助 ESP32 如何配置 CAN 双滤波器模式 ?

首先要 根据 Dual Filter 模式计算 acceptance_code 和 acceptance_mask 值 。然后在配置 can_filter_config_t 时候将 single_filter 变量设为 false 例 Filter 1 会接受所有从 0x0F 到 0xFF 的 Standard ID 包(包括 RTR ) Filter 2 会接收所有从 0x7F0 到 0x7FF 的 Standard ID 包 (包括 RTR ) acceptance_code = 0x01E0FE00 acceptance_mask = 0x1E1F01FF static const ca...

Re: Eclipse still showing "unresolved inclusion" and "Symbol couldn't be resolved"

@dasarne I think there are two separate issues here, namely Eclipse not building and Eclipse not parsing compiler output . Eclipse Not Building IOError: C:/msys32/home/Arne/esp/esp-idf/Kconfig:59: Could not open '/home/Arne/esp/esp-idf/components/bootloader/Kconfig.projbuild' (ENOENT: No such file o...

Re: Eclipse still showing "unresolved inclusion" and "Symbol couldn't be resolved"

@dasarne by log I mean the Build Log. You can enable it under Project Properties->C/C++ Build->Logging and check Enable Build Logging . Run a full build to generate a complete log output (i.e. clean the project before building all ). From the screenshot you've provided of the CDT Build Console it se...

Re: Eclipse still showing "unresolved inclusion" and "Symbol couldn't be resolved"

On one or more of your project files that are showing unresolved inclusions (e.g. main.c), could you post a screenshot of those files' CDT GCC Build Output Entries (see screenshot below). A log dump of your Eclipse build would also be helpful.

Re: ADC_VREF already calibrated on ESP32_WROOM_32D

I flashed the "adc" example in ESP-IDF which route to GPIO26 the Vref. I was expected to find 1114mV, but in reality I measure 1100mV (the "per-design" reference voltage). A difference of 114mV seems abnormal. Are you sure you're measurement equipment is correct? Could you also call espefuse.py sum...
