Part Number: F280025 在参考手册TRM(spruin7a) 24.2.1.3 SCI Baud Rate 章节介绍波特率计算公式时提到:
The SCI/LIN has an internally generated serial clock determined by the peripheral VCLK and the prescalers P and M in this register
这个外设时钟VCLK应该就是在前面3.7节时钟树中讲到的PERx.SYSCLK吧,这个外设时钟有从SYSCLK分频吗…
In the table below the RECOMMENDED OPERATING CONDITIONS in the CD4024 chip specification, when the chip is operating at 5V, the maximum input pulse frequency is 3.5MHZ; In the table below DYNAMIC ELECTRICAL CHARACTERISTICS, when operating at 5V, the maximum…
Part Number: TMS320F28034 Other Parts Discussed in Thread: LM5041
公司想把LM5041做成F28034控制的。驱动无法实现
一、上图是LM5041电源管理芯片的pwm驱动时序,buck驱动Q1,Q2是130kHz。推挽驱动Q3,Q4频率是65kHz。Q1的上升沿必需在Q3与Q4同为高电平时。Q2的下降沿也必需在Q3,Q4同时为高电平时。频率不一样四个驱动没法对齐 。用DSP有没有办法实现?
二、因为频率不同无法相位同步,如果不使用相位同步寄存器…
