Sorry, but this is not really a question as much as some interesting information.Until yesterday all of my ST applications were working perfectly on a Debian v10.9 installation. Then I started getting this message....../STM32_Programmer_CLI: symbol l...
However, For similar level translator device like "54AC164245", there is an explicit requirement of sequencing of 3.3V and 5.0V . Please confirm and clarify.Then datasheet of device "54VCXH163245" says VCCA must be higher or equal to VCCB, but for "...
As i am new to building my own Microcontroller shield , i want some help ! I want to achieve a high speed USB connection with PC to transfer data from micro controller to PC . Now Do i need a external peripheral with the micro to get the HS connectio...
Hello,I have a need to make the S2-LP communicate to an existing RF system which is based on the nRF905. From the reading I have done it looks like it should be possible. Does anyone have any suggestions on how to configure the S2-LP to do the job?Th...
Hey there community, I am trying to set up a active NFCIP-1 communication between two ST25R3911B chips (X-Nucleo-NFC05A1 Board).I was able to get the communication running without the library (because I can not use it in the following project), in ab...
Hello We're using BlueNRG-2 VTimer to be RTC for wake-up the system when it's in sleeping mode.when we set the timer 10mins, it still wake-up the the system every 15 sec.HAL_VTimerStart_ms(0, 600000);But I don't turn on the other timer such as 1 or 2...
Hi, We are currently using the BlueNRG-2 with GNU ARM GCC to compile and run everything. We based our projects on CMake and GNU GCC toolchain to build by using the examples for the Atollic IDE (eg. the linker script, etc). We are now evaluating the B...
Recently I started to use the BlueNRG-LP,and I choosed BlueNRG345AC。I designed a PCB based on the STEVAL-IDB011V1. I try to run some example code on my design with KEIL MDK-ARM.It just totally dosn't work.the debugger is CMSIS-DAP,and I found everyti...
Hello, back in April in repsonse to a support question about developing a BLE project we were pointed to use a BLUENRG-M2SP board (along with a Nucleo-L476RG). These arrived and we were able to get the android app working where we can see the RSSI ch...
