Teseo-LIV3R - I2C comms - 0xff bytes prepended to response - bus hang !

I'm using I2C to communicate from a master I2C controller to the Teseo-LIV3R device.I'm periodically sending $PSTMNMEAREQUEST messages to get an NMEA message generated from the device. I see the NMEA message generated, followed by an echo of the requ...

Alternatives to TC2030 tag connectors

What kind of connectors do you use, when there's no space for soldered connectors for flashing your boards?I wonder if there's a wider distributed (and cheaper) solution than TC2030-nl connectors. Those are nice, but waaaaaaay too expensive.

How to have a READABLE Characteristic to a BlueNRG-M2SP

I try to read the data from BlueNRG-M2SP on an android application. For that with my STM32 I send to the UART a "u". On the application, I scan the services and Characteristic and I only find a write Characteristic but no read Characteristic, and I c...

Is there any register map description for STUSB4761, i didn't find it. I need register map description document for STUSB4761

Hey! STUSB4761 USB PD IC, I2C Device address missing??

I need STUSB4761 I2C Device adress. In the datasheet I can not see.And I wanna use this pd with MCU and I2C controlled buck-boost converter. I will read STUSB4761 registers via I2C and after that I will control the buck-boost IC via I2C so input will...

BlueNRG-2 dual role configuration

Greetings,I am developing a multi-slave configuration using a few BlueNRG-2 modules where the master would also connect to a smartphone and transmit data collected from the slaves (a tree network). Though a dual master-slave (central-peripheral) role...

for ( j = 0; j < 8; j++) { GPIOB-> BSRR = (j); HAL_Delay(10); GPIOB-> BRR = (j); HAL_Delay(10); }

Hello.When the A0,A1,A2 pins of 74HC138 are 0,0,0 Pulse is weird.I wonder what the cause is.

Is there a way to use WIFI module and Bluetooth module simultaneously?

Greetings,For a project of mine, I would like to use on B-L4S5I-IOT01A IoT discovery kit both Wi-Fi ® (Inventek Systems ISM43362-M3G-L44) module and Bluetooth® Low Energy (BlueNRG-M0) module, in simultaneous.Reading the user manual for the board (UM2...
