Re: ADC1

The 12-bit ADC has a maximum raw reading of 4095 meaning the ADC is maxed out. Change your ADC attenuation to support a larger voltage range.

Re: About remote frame sending in CAN (ISO 15785-2)

Note: sending CAN TX with the RTR setting does not work. Could you elaborate more on the specifics of the issue you're facing Is there any activity on the bus when attempting to send an RTR frame? Is the receiving node acknowledging the RTR Frame but does not transmit a Data Frame in response? Is y...

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...
