Greetings,I'm having a UART Frame Error (identified by relevant bit raised in UART ISR, and relevant error flag routine in UART_IRQHandler) when attempting to running LPUART1 off a 120MHz SysClock on a STM32U575RG present on our boards.I've replicate...
Hello everyone,I hope you're all doing well!I just wanted to take a moment to express my gratitude for all the guidance and assistance I've received from this community. Thanks to your support, my learning journey with ST Microcontrollers, particular...
Hi, I'm wondering if write and erase external flash menory can be done when XIP mode on the same external Octal-Flash?I read RM0477 Rev 4.pdf and it told not recommand to programm the flash in this mode, and indirect mode can do that.Since the MX66UW...
Background:I am capturing an image on OV5640 Camera module. My camera is connected with STM32L4R9I over DCMI protocol. I am further using DMA1 to take image data and store it in PSRAM (with the help of FMC). From PSRAM, image data is being written on...
During transmission and reception using STM32U585 LPTIM+SPI+LPDMA, noise to SPI3_SCK causes a fatal bit shift in the bitstream. The condition on the left is normal and the oscilloscope waveform can be received exactly as expected.However, if you intr...
I am trying to implement a USB mass storage using USB3300, STM32H723, and e eMMC. Project Setup:* Clock configUSB_HS ConfigUSB Device configeMMC configIn the code I made these addons in the "usbd_storage_if.c" file:Currently, my custom board is worki...
Hi,I have a PCB with F411 as MCU.MCU VBAT pin is directly connected to battery positive pin.I try to use ADC1 to read the VBAT value. Here is the ADC1 init code: ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC1_Init 1 */ /* USER ...
I am using the STM32 Nucleo F411RE, and have 5 GPIO pins set up as inputs, each set to trigger an interrupt on the rising and falling edge, configured to use the internal pull down.However, what I am finding is that causing a level change on one of ...
Dear friends,I am developing a controller using stm32f407vgt6 microcontroller and I'd like to add the capability of firmware upgrade through Ethernet port in my controller.I've read about Ethernet IAP (In-Application Programming) UM1709 but it is no...
Hello, i've been trying to get SPI working in conjunction in DMA.But with "bare metal register implementation" i can't even get the NSS working properly. The Stm32F730 needs to hold NSS/Chip Select high all the time, except for when communicating wit...
