Hi everybody,I'm using a LSM303AGR and I got some difficulties to read the temperature.My I2c functions, because I can read "who am I" registers, and I tried to write then to read some registers. I did the following steps : LSM303_IO_Write_one_by...

Hi everybody,I use a STM32L476RG. I'm trying to write 4 bytes in the flash memory on a PVD IT.I can write/read in the flash, it works.I've programmed my PVD on level 6 (2.9V) and BOR level is at 1.7V. I've used AN4718 to design a vbat system with a s...

Hi everybody,I have a custom STM32 board. I'd like to use ANT7-T-ST25DV64KC dev board to use NFC functionnalities. I have red that I can use X-CUBE-NFC7 to communicate with this board.In my cube MX, I have choose custom/NFCTAG7, I can configure IC2/...

Hi everybody,I'm working on a nucleo-L476. I'll like to write some data in NFC tag M24SR64 (I'm using a dev board ANT-7-M24SR).First, I developped functions to read into ndef memoru on ESP32 dev board. It works well (I can read my message with ST app...

Hi everybody,I'm using a STM32L476RG. I use the usart2 to transmit/receive frames from an external sensor. The reception is working with DMA1 channel6 (I use Transfer complete and idle line interrupts), and it works very well.I'd like to add a timeou...

Hi,Thank you for all your answers.My application is enough simple. My goal is to read with a smartphone a serial number that I stored previously in the ST25 EEPROM's - NDEF (I succeed to do it with a M24SR64).Then, I'd like to write some data into th...

Hi,Thank you very much for your answer, now I can compile (and there is no more warning triangle ;-)).Is there an example of the using of all these functions ?Regards,

Hi,Thank you for your answer.I used the version 6.6.1 of cube MX.Find below screen shots from my cube.

By checking the datasheet, the last byte of reading operation is NACK, so that's normal.I've also modify my way to read by adding function "HAL_I2C_IsDeviceReady", now it starts to work better.

by making a reset of DMA/UART, it works but it's a weird method.
