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...
Hello, I am using the B-U585-IOT02A board with Zephyr. I can't see how to use the MXCHIP EMW3080 Wi-Fi chip. Has anyone made this work? Thanks
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...
Hi,We design a custom board with STM32L081KZ microcontroller. In this board we add an inclinometer that comunicate with the microcontroller by using SPI. In the firmware project we use this library: GitHub - ohilab/libohiboard: OHIBoard library. We u...
Issue Description:I am trying to configure ADC1 on PA0 (Channel 16) in continuous mode on the STM32H750 microcontroller. However, the code gets stuck at: while (!(ADC1->ISR & ISR_EOC) && --timeout); // Wait for End-of-Conversion This suggests ...
Hi, I try to update the firmware of an STM32L431 with another microcontroller. I use a UART interface to do that. As described in AN3155 §1, I send the 0x7F after managing the Boot0 and reset pins, and I wait for the 0x79 (Ack). But the STM32 answer:...
