Dear All:
我想知道如何設置ADcmXL3021 MTC模式嗎？ 有任何文件或流程設置規則可以參考嗎？ 我需要ADcmXL3021 MTC模式初始SW代碼(initial SW Code)，希望為我提供加速的產品開發
Best
Jack
The MTC configuration can be found in the DS. We have an evaluation setup that you can test these features with. Here is a link to the wikipage. Here are some examples that can help.

Dear Sir:
This S/W Code only focus Cypress FX3 ,ADI provide open source S/W code to support any one system?? (ex:STM32F xxx ,arduino ,Raspberry Pi)?? thanks

I'm looking for a routine for the adcmxl3201 program
