MSP430FR5969: MSP430FR5969: ADC 2 adc output and wave visible

Hi,

I am using MSP430FR5969.

1. For 12-bit ADC. I want to read analog data from A0 and A1. But I am not sure how to write with CCS, which should be watched through the wave of changing on computer.

2. If I want to design the PCB board with smallest system of MSP430, could I download to MSP430FR5947 IC chip by using MSP430FR5969 launchpad download? Is there anything code should be mensioned?

3. How do configurations could let two channel adc output with the same interrupt and same time plot?

4. How to calculate the ADC12 sampling frequency?

Thanks so much.

你好，

1. 在CCS中可以查看转化后的结果，查看ADC12MEMx（x = 0 到31） 寄存器，有关寄存器的说明在userguide中有描述。

2.两者的电路结构不同，各类寄存器其代码的设置也可能不同，具体可以参照userguide。

3.你可以将两个通道中断指向同一个中断服务函数，但由于只有一个ADC，两个通道转换之间会有细微的时间差。

4.请参照datasheet Table 5-23：
