Interface and connectivity ICs

Hi, I'm interfacing Nucleo-L476RG with a UART Device. If I power off that devices, my Nucleo code freeze and I need to manually reset it. I need to power-on and to power-off the device and the Nucleo must continue to works.

Nucleo send through UART4 and receive with DMA from devices. Then Nucleo send to PC via USART2 for debugging. In UART4 there is Idle Line detect for receiving unknown length of data.This is my code: MX_GPIO_Init(); MX_DMA_Init(); MX_UART4_In...

Where is the ST21NFCD Detailed development manual?

I need it please give me a url.

X-NUCLEO-BNRG2A1 range is less than 10M on highest power level

Hi,I am experimenting X-NUCLEO-BNRG2A1 board and I have found the range is not as I hoped (about 5 Meters without any barrier).I have set the power to 1,7 which I believe the highest power level +8dbm.Is there any way to extend the range?Does using e...

ST202EB ST232: Can V+ be connected to GND via capacitor (as MAX232 devices)?

I'd like to use the ST202/ST232 as a drop in replacement for MAX202/MAX232 devices. In my design, the V+ output is connected to GND (via capacitor) as suggested in the datasheethttps://www.ti.com/lit/ds/symlink/max232.pdfWhereas the ST datasheethttps...

I have the following question: Is It possible to use SBSFU on BlueNRG-M2 module? Is There a X-CUBE-SBSFU package or similar to use with this module to implement firmware security update via OTA?

I followed the webinar "Discover our STM32 security ecosystem, from theory to practice online workshop".I had to use the module BlueNRG-M2 , is there a package or other to implement firmware update security in this module?Thank you

We are developing a product that needs to support (and be powered from) either a PD power supply or a non PD power supply - we do not know which the user will connect. Can someone please let me know what is the right architecture here? Thank you, Nir
