acceptance_code对应文说的CODE 寄存器:Code 值将指定一种位排列模式,每条 过滤报文中的位都必须匹配该模式,才能使该报文通过过滤。 acceptance_code对应文说的MASK 寄存器:Mask 值可屏蔽 Code 值中的某些位(将屏蔽位设 置为“不相关”的位)。 从上图我们可以看住,code寄存器和 接收的ID为 xnor
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...
.acceptance_code = 0, //验证代码 .acceptance_mask = 0xFFFFFFFF, //验证掩码 0xFFFFFFFF表示全部接收 .single_filter = true}; // true:单过滤器模式 false:双过滤器模式 ESP_ERROR_CHECK(twai_driver_install(&g_config, &t_config, &f_config)); ESP_LOGI(EXAMPLE_TAG, "Driver installed"); ES...
Hello, Can somebody calculate for me the acceptance_code and acceptance_mask values? I want to receive only the 0x17330800, 0x17330810 and 0x5F0 IDs. Thanks in advance.1 post • Page 1 of 1 Return to “Hardware” Jump to Who is online Users browsing this forum: Baidu [Spider], ...
