Issue in STM32F746 - KSZ8863 interface

I'm trying to use a KSZ8863 Ethernet PHY with the STM32F746G. We have used the RMII interface to connect with KSZ8863 and running at 50MHz frequency .RMII pins are connected to KSZ8863 based on MAC mode interface.To test the KSZ8863 ,We have used stm...

Ble Receiving Junk data

hi all i am using blenrg2 m2sp chip as network mode. its operating as peripheral device and communicating with host controller through UART with 115200 baud rate .I received BLE read characteristic request , i did not response till 1 second ...

S2-LPTX module different supply levels for analog/SMPS and digital

Hi!I am designing my own sigfox board using S2LPTX module, some sensors and a ST microcontroller. Microcontroller and sensors are working on 1.8 V supply. I know that S2LPTX module can work with VBAT = 1.8 V, but in section 3.2 it mentions VBAT shoul...

Hello, I have problem with connection between JLINK and custom board with BLUENRG_LP chip.

I have BLUENRG-LP chip on my custom board and I'd like to flash beacon example inside. The example is one from BlueNRG-LP-DK-1.0.0 named BLE_Beacon.As the debugger I try to use JLINK (tried CMSIS-DAP configuration as well) but I'm not successful.This...

TESEO LIV3F - update rate says 10Hz, does that mean it is updating location based on satellite data at 10Hz? Or is it using interpolated data ? Does this module have an integrated IMU?

S2-LP (and its GUI) problems

Hi!I have S2-LP connected to S2-LP GUI (only difference - it has no EEPROM on board, so I recompiled CLI firmware with EEPROM_NO define, and it has quartz running at 25MHz). I have to receive packets with 30-50kpbs datarate, but I made slower packets...

How to read data from pins? STM32F4

Hello everyone, I would like to know how to read data from pin on STM32F4. I have a small project where I am blinking led (it's running throw Arduino board) and I would like to see throw STM32F4 when it's on and when it isn't. How should I setup pin?...

STM32CubeProgrammer and ST-LinkvX {any version} stopped working...

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...

I am using "54VCXH163245" bidirectional level shifter in one of my ongoing projects. I am using VCCA as 3.3V and VCCB as 1.8V. My queries are: 1. Is there any power-on sequencing requirement for 1.8V and 3.3V for this device.?

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 "...
