I'm trying to update a transmitter called a wfly et16s. They have downloads on their site to upgrade their radio to expresslrs which is just a newer protocol. I installed the stm32 driver and it shows its working, I can connect to stm32cubeprogramme...
I saw on NUCLEO-U5A5 schematics - there is a level shifter for signal T_VCP_TX:a bit obvious: if MCU jumper is set to run on 1V8 VDD - an external UART receiver (e.g. CP2102N) would not get anymore correct UART_TX signals (yes, it does not anymore wi...
I'm trying to get the LPUART working with BDMA on a STM32H7A3 MCU. Eventually I'd like to set it up so the MCU goes into a low power state and wakes up when it receives a LF character match in the incoming message, but for now I'm just trying to get...
Hello.I'm trying to wakeup the STM32U5 controller (U575ZI Nucleo board) when a byte is received using the LPUART.I'm using the LSE clock for the LPUART. Without entering the stop mode, the LPUART interrupt is triggered whenever a byte is received. Th...
Dear ST professionals,Continuing the previous problem reported at https://community.st.com/t5/stm32-mcus-products/mb1641-nucleo-stm32wb15cc-slowness-between-ble-and-uart/td-p/603759, I have problems when use LPUart to wake up from STOP Mode. I tried ...
Hey folks, I am using UART RX in DMA mode using 512 byte buffer. My code sippest working fine. I have one question.Q. Suppose you have recevied 12 bytes but you have set 512 length so, rxCmplt() callback will not called. Right? But I wanted to stop U...
I'm fairly new to low-power and sleep-mode applications of STM32H7 microcontrollers. I've been trying to read through the documentation, but I'm having trouble getting a whole picture idea of how this works, and connecting all the information from th...
Hello everyone,I'm working on a project where i use 2 STM32 MCU which communicate with each other with LPUART and DMA.My STM32 references : STM32L072CBT6 and STM32L010C6T6I have a problem with this communication with LPUART and DMA. I see that error ...
Hello everyone,I'm working on a project with a STM32L072CBT6.I'm using LPUART (PB10 / PB11) at 9600 bauds to communicate with an other board. For low power consumption, i'm using LSE for my LPUART.When i check my bauds rate on my oscilloscope, i get ...
Hello, I am using the embedded coder support package in simulink to interface with my onboard MEMS acceleration sensor (LSM303AGR) on my STM32F411VET discovery board. I could successfully connect and run simple LED program through USART2 on simulink ...
