After inspection I realized that RCC_CFGR register is different when running in different modes (debug and normal). I fixed the issue by writing RCC -> CFGR = 0x1F040A. Now the register is the same but the problem still exists.another strange fact i...
We are building solution to identify post box filling level with VL53l1x proximity sensor. Letters in the post box may be aligned in a Zig jag manner .As per our knowledge laser beam (time of light) can identify distance between the sensor and plane...
I have a problem with modbus-rtu communication in my stm project.The STM32F446RE is connected to a MAX485 board by UART1 to RO-DI pin and by a GPIO pin to RE-DE.A typical instruction (variable:INSTRUCTION.array_instruction) is something like 01 06 26...
Hi all! I developed custom board with S2-LPQTR and STM32 uc. S2-LPQTR - answer through SPI and transmite to radio channel through BALF-SPI2-02D3, but don't receive any message.I connect on SMPS2 pin external 1.8V from LDO. In all example boards inte...
Hi I am using Bluenrg_m2 expansion board X_Nucleo_Bluenrg2 along with the controller Stm32l476rg. Reffered example is 'SampleApp' form X_cuble_BLE2_v1.0.0.I am trying to send 160 bytes of the fixed data over BLE frequently but after sending one packe...
Hey There, Firstoff : i just started using the STM32 boards and my not know everything to expect me to..Ive got two STM32L432KC boards and two SX1261 MB2 LoRa.Shields.I want to implement a direct communication between them without any Gatewayas / Lor...
I want to make a usb hid keyboard stm32. it possible in addition to the 6 keys that I transmit to add another byte in which to contain a variable that can be read by the application on the computer? Ex: | 0 - Key modifier | 1 | key1 | key2 | key3 | k...
Greetings,I am working on a project where I am updating hardware from the SPBTLE-RF module to the BlueNRG-M2SA module. I have upgraded the module and am now looking into what I have to update on the software. Effectively, I am upgrading from BLE 4.1 ...
Hi,Bought the STM32 Nucleo kit w. USI Lora shield.Disappointed when I found out that the documentation wasn't that great.When using AT_Master or the End_Node example I dont find any options for retrieving the debug data.... Is the only option I have ...
Dear Team,I use stusb4500 and desgin this circuit,I connected type C with this circuit and measured VBus got 20V, then a few seconds later stusb4500 broke down.Anything i have lost in this circuit then made it broke down? How to fix this circuit to ...
