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, ...
I try to generete interrupt when CNT register reach any value. But It generete when I enabled to interrupt EGR bit is always zero. when I try to change accept first bit not effected.It is configuration capture = TIM_GetCapture2(ExternalOSCTimer); TI...
