[National Technology Automotive MCU N32A455 Development Board] 1. Development Board Test [Copy link]

【grateful】

Thanks to EEWORLD Forum and National Technology for providing me with the opportunity to conduct this evaluation.

【Foreword】

I am participating in the review as a substitute player this time. I have been testing ADC recently and happened to see that this development board has 4 operational amplifiers (OPAMP), so I want to try their OPAMP.

【Evaluation plan】

1. Use electronic load + data power supply to build a 10-20 microampere experimental environment.
2. Use 4 amplifiers to amplify and import into ADC.
3. Use DMA method to obtain the voltage values of four channels.
4. Use the display to show the test results.
5. Compare with ADS1115 and similar voltage detection modules.

[Unboxing]

The board I got was one that the boss had unpacked before. It didn't come in the original box, but in an old box from Digi-Key. There was only a bare board inside, and the data cable was gone. So I tested it first to see if it was normal.

Download the SDK package of N32A455, open the project and check it with Keil. I recognized the chip, which means there is no problem, so I felt relieved.

Then download the blink project under GPIO. The development board can light up normally, indicating that the board is OK.

【material】

In fact, when you download the SDK, National Technology provides very complete information, including documents in Chinese and English. This is a very exemplary practice for Chinese semiconductor manufacturers.

Next I will put a lot of effort into studying, and hope everything goes well!

Dear moderator, you have a grateful heart. I haven’t seen you update recently. Are you on vacation?

I went home for the Qingming Festival. It is not convenient to bring too many devices home. I am learning Rust language recently. The update may be slow.
