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 ...
Hello,I'm new to STM controllers and working on a project where the STM gets data over serial line from another microcontroller. For this UART1 is turned active and mapped to ports PA_9 (TX) and PA_10 (RX), so data from other controller flows in on P...
Hello,first, I'm new to STM32 Nucleo MCUs, so if I am asking something that is well-known in documentation of Nucelo boards please advise me to correct documentation.I have a project using a STM32 L432KC that gets serial data from another MCU and sen...
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...
Hello folks, we are working on an application where STM32L072CZ needs to wake up from STOP mode on a data received interrupt on UART and LPUART RX lines. We are aiming for STM32L072CZ to be in low power mode and needs to wake up when an external sens...
Hi,I am using ThreadX and the STM32L4A9 processor. When my application is ready to sleep I call an enter low power function. I followed sample code from ST Cube example which disables the GPIO CLKs and enters STOP Mode 1.//ENTER Low Power Mode/* Dis...
Hello,I have a problem with the Controller. For some time the Uart is working fine. Than the UART receive Interrupt is not generated anymore.I check the working pcb with the debugger and the scope. I see there is no Signal on the pin. The uart from t...
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...
