I'm using STM32f103C8T6 Blue pill. for IDE is CUBEIDE and using HAL librarywanna receive data from producted BMS module, then additionally control the mcu by received datas. BMS communication module setting is 9600 8-Even-1 by 485 communication.i wa...
Hello,I know that LPUART can wake up MCU from STOP mode. But I'm unable to send data using DMA when entering STOP mode. I use LSE and 9600 as baudrate, so transfer takes a lot of time. I need my core to be in stop mode to reduce current consumption.I...
always stuck in here Error_Handler, and only TxData can load Message successfully twice, so I think it's because of the Callback function is not triggered, so the transmission is interrupted and also RxData didn't receive message.Here is the Callback...
The STM32U5 Errata Sheet (ES0499 rev 5 is the one I am looking at) has errata 2.2.1 which says: "The LSE frequency can be incorrect when PC13 is used as output for RTC_OUT1 or TAMP_OUT2 function". The workaround: "The RTC_OUT2 function must be used ...
Hi i'm trying to get the LPUART (PA3, PA2) pins to communicate with my computer via the serial port, but i can't get anything to work. Here is what i'm trying to use at the moment...Sysclock Config:#pragma once extern "C" void SystemClock_Config(vo...
Do to the ongoing lack of availability of the STM32F767VGT (and no news on when this will be resolved), we've dropped an STM32F765VGT on to the PCB as a possible substitute. STMCube32MX says I can map the pins the same way, but the Ethernet doesn't w...
I am using a STM32L073RZT6 MCU and the Cube IDE V1.11. Using the .IOC, I instantiated UART1 on PB7-6 with global interrupts enabled and a DMA service for RX. On the PC side of things I'm using PuTTy as a sniffer and a UART to USB cable for COMS. I ha...
Alright, I am searching the STM32L4 reference manual (RM0351), and as far as I can see, there is no description of how the UART is expected to behave when various "reception error" flags are set. In my case, I am observing NE when resetting a modem, ...
