status_t SPI_DRV_MasterTransfer(uint32_t instance,
const uint8_t *sendBuffer,
uint8_t *receiveBuffer,
uint16_t transferByteCount);

把这个函数的的 sendBuffer 设为 NULL，就是只接收，
receiveBuffer 设为 NULL，就是只发送

改成经典CAN帧，需要将TX_DL改为8，后期的升级应该会加校验功能

补充一个问题：
怎么开启和关闭同一个eTMR1指定通道的输入捕获，要求开启和关闭时不会对其他通道产生影响。如eTMR1_CH0和eTMR1_CH1均在执行输入捕获，这时要对eTMR1_CH0进行停止或取消输入捕获，不对eTMR1_CH1的输入捕获造成影响

这样就OK了吧？
eTMR1->CH[0].CTRL &= ~eTMR_CH_CTRL_CHMODE_MASK;
eTMR1->CH[0].CTRL |= eTMR_CH_CTRL_CHMODE(00);

These information are in CORE->SCB, however not much information will be recorded in Cortex M0

Cannot directly assignment by means of pointers dueto in flash array.
You may use the flash operation, such as FLASH_DRV_EraseSector.

Diga 明白了。感谢

这个是KEIL的问题，建设试用ozone来调试，也能画图

谢谢，我这边学习下

定时器电平翻转应该就是etmr的output compare模式

可以参考以下帖子排查adc采样相关问题

Hello ，Currently, there are no plans to update this ADC self-test information.

🤕

是不是PowerDown模式CAN唤醒啊？

配置内核SCB寄存器：

SCB->VTOR = 0x6000;

run 好的，谢谢
