配置 digital0 引脚会导致重启循环 #133

thinkl33t

我有一个4 轴外部驱动器控制器，我正在从 grbl_esp32 迁移到 fluidnc。截至昨晚运行最新的 github 版本：

[MSG:INFO: FluidNC v3.2.5]
[MSG:INFO: Compiled with ESP32 SDK:v3.3.5-1-g85c43024c]

我遇到的问题是，每当我尝试配置数字输出时，我的电路板都会出现恐慌并进入重启循环：

[MSG:INFO: Probe Pin: gpio.32]
[MSG:DBG: mc_reset()]
[MSG:ERR: gpio.21]
abort() was called at PC 0x401ab95b on core 1

ELF file SHA256: 0000000000000000

Rebooting...

我的配置文件的相关块如下：

user_outputs:
  analog0_pin: NO_PIN
  analog1_pin: NO_PIN
  analog2_pin: NO_PIN
  analog3_pin: NO_PIN
  analog0_hz: 5000
  analog1_hz: 5000
  analog2_hz: 5000
  analog3_hz: 5000
  digital0_pin: gpio.21
  digital1_pin: NO_PIN
  digital2_pin: NO_PIN
  digital3_pin: NO_PIN

如果我将其更改为：

user_outputs:
  analog0_pin: NO_PIN
  analog1_pin: NO_PIN
  analog2_pin: NO_PIN
  analog3_pin: NO_PIN
  analog0_hz: 5000
  analog1_hz: 5000
  analog2_hz: 5000
  analog3_hz: 5000
  digital0_pin: NO_PIN
  digital1_pin: NO_PIN
  digital2_pin: NO_PIN
  digital3_pin: NO_PIN

引导成功完成。

您是否尝试过使用 I2S 等效引脚，而不是将 GPIO 用于步骤目录和启用引脚？请参阅https://github.com/bdring/FluidNC/blob/aaf3a3afe7a31c6a7fb2bef009864e1534a14a12/example_configs/6_pack_external_huanyang.yaml中 6_pack_external_huanyang.yaml 中的示例。例如：X 轴 step_pin: gpio.0 使用 step_pin: I2SO.2 代替，其余轴依此类推。

6pack 使用 i2s 端口扩展器提供这些引脚，它们不直接连接到 ESP，我的 4 轴板使用直接（很好，缓冲）esp 引脚连接
