Resolved! How about STM32l4 power consumption
我有一个能源供应项目，并购买了X-NUCLEO-NFC07A1和NUCLEO-STM32L476RG。但是，我在EN中使用了EH代码。X-Cub-NFC7，现在我想根据此代码降低能耗。我应该如何编辑代码，使STM32L4具有最低的功耗并且只能完成LED闪烁测试？

Hello community,I´m trying to use LL driver for the communication with ST25DV64KC chip, the register address of this chip is 16bits, but the current LL driver only supports 8bit, I tried to adjust it and failed. Do you have some LL driver examples f...
Resolved! Issue with I2C mailbox write and read
Using st25DV tag on our embedded system. In short, the second I2c read does not display the same data that was written. It differs, as the first byte changes to 0xFF. When I write to the mailbox the first time, and then read the data, it's the same. ...
Resolved! ST25TV
Hi,I want to know if there is a provision to lock an entire area in ST25TV tags. I can see from the datasheet that blocks 0 and 1 can be locked, but I cannot see anything for other blocks. I know that I can use a password to do same but I do not want...
