HI:
Requirements:
The 8-channel collection rate is 1ms
Design Scheme:
MCU using stm32G070
Frequency 64 MHZ
Difficult points:
1、Every conversion of MCU needs to pull down CS, MCU is too inefficient
2、SPI+DMA, 5US is going to be an interrupt. It doesn't make sense
For help：
Is there any other way to deal with it
Amy Luo：
您好，
是的，每次需要拉低CS以启动转换；
kan kaifang 说： 2、SPI+DMA, 5US is going to be an interrupt. It doesn't make sense
8-channel collection rate is 1ms，每个sample的时间是125us，也就是8KSPS的采样速率。
您是打算用DMA的方式来读取转换数据吗？5us这里是什么意思？
