Description: ,片选接到p1.5
复位端 p1.4
中断端接到 int0
82c250工作在斜率模式下 ，RS 接51k电阻到地。
2，SJA1000与82C250的接口，逻辑上为SJA1000输出0（显性位），表现为低点平输出给82C250，则82C250输出
差分的低电平。SJA1000输出1（隐性位），表现为高电平或悬空输出给82C250，则82C250输出悬空状态。
3,周立功的中SJA_BCANCONF.ASM中对输出控制寄存器 的TX0的输出 极性的位的定义不对。
还有里面定义有接收错误标志码，不知道何时用。-, The election received a P1.5-chip client p1.4 interrupt reset int0 82c250 client received in the slope mode, RS then 51k resistor to ground. 2, SJA1000 with the 82C250 interface, logic for SJA1000 Output 0 (dominant bit), showing low level output to the 82C250, while the low-level differential output 82C250. SJA1000 Output 1 (recessive), and the performance of the output is high or left vacant to the 82C250, the vacant state 82C250 output. 3, Zhou Ligong in the SJA_BCANCONF.ASM of output control register TX0 output polarity bit the definition of wrong. Inside the definition also has to receive error flag code, I do not know when to use. Platform: |
