Hello,I am working with the STM32L432KCU6 microcontroller and noticed that it includes a 32.768 kHz crystal. I would like to confirm whether there is a separate crystal for high-speed operation or if an external high-speed crystal needs to be added. ...
Dear fellows,I've been trying to use OCTOSPI just as serial-to-parallel I/F which is protocol-free, continously working...I'm not intending to interface with any existing serial-memory devices. That's why I noted "protocol-free".Intending just have a...
UART2 config .ioc config UART3 configConnectionsconnections output hercules Project Overview: I'm working on a communication setup between two STM32 boards: a master board (STM32F446RE) and a slave board (STM32F401RE). The goal is for...
Hello, everyone!I've been searching for an answer to this question for a long time, but so far without success.I have an STM32F410 and would like to use a timer to trigger ADC readings. However, TRGO does not appear as an option for the ADC trigger s...
Hi,Im currently working on a project with an STM32L452 that uses a Temperature Compensated Crystal Oscillator (TCXO) as the Low-Speed External (LSE) clock source. The TCXO is responsible for clocking the RTC. To fully calibrate the TCXO, I have desig...
Hello !I have a problem : I'm looking for a way to know the origin of a wake-up from standby mode.I'm using STM32U083C Discovery Kit.In my application, MCU can wake-up in two different manners : an external wake-up pin and an RTC periodic wake-up.The...
Hi, I am using UART3 and UART4 interrupts together in STM32G070RBT6TR processor and facing issues.I have inserted my service routines as below. /* USER CODE BEGIN USART3_4_IRQn 0 */ if((USART4->ISR & USART_ISR_TC_Msk) == USART_ISR_TC_Msk){ } if((US...
Hello, I am implementing I2C slave device with STM32G431. Using DMA with HAL library, it works well as expected in normal situation. It normally get ready to receive runningHAL_I2C_Slave_Receive_DMA(&hi2c1, (uint8_t *)aRxBuffer, rx_length)and handles...
Hi,I am testing the USB HS Device CDC implemented from the CDC example (so using ST middlewares) and I notice a strange behavior while reading transfers of 512B.Internally, the function CDC_Receive_HS file Appli/Src/usb_cdc_if.c has been adapted for...
Hello everyone.I am encountering a very strange issue with the STM32H7B0 using the J-Link to debug.I followed this tutorial to control the WS28B12 LED using Timer, PWM and DMA.I use the following function to transmit the PWM data. if (HAL_TIM_PWM_Sta...
