I understand the STM32H7's BDMA requires special attention to the memory map [FAQ: DMA is not working on STM32H7 devices]however, when I try to declare the buffer to SRAM4 that will be the destination for the ADC DMA transfer, __attribute__((at(0x380...
I am working on OTG FS application on stm32f769 discovery board, as per the it's schematic for OTG_FS VBUS power supply will be taken care by External Phy(see below image). So as per that I configure the STMCUBE IDE, and i disabled the VBUS_Sensing a...
Hi,I am working on freertos plus tcp library with STM32H563ZI, but how must I make memory otions in linker file?like: RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 320KFLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048KRAM1 (xrw) : ORIGIN = 0x20000000, LENG...
I am making a product and trying to write a serial number. After looking into it, I heard that I can use the unique device ID to write the serial number, but I understand that the unique device ID is read-only. I am curious as to whether the previous...
The datasheet say:USB on-the-go high-speed (OTG_HS) The devices embed an USB OTG high-speed device/host/OTG peripheral with integrated transceivers. The OTG_HS peripheral is compliant with the USB 2.0 specification and with the OTG 2.0 specificat...
I've encountered an issue while implementing code on an STM32L476RG Nucleo board to receive variable-length data from Tera Term using USART2 in asynchronous mode. The baud rate is set to 1 Mbps with a 16 MHz sysclk. However, the code doesn't accurate...
Hi I am here to seek help from the community.I am a Research Student I just want to know how to send ADC values from one STM32F446RE to other STM32F446RE (i have two). and I am using MCP2515 Transceivers at both ends. need help in this thank...
I have a small amount of per-device data (e.g. hardware revision, serial number, manufacture date) that I would like to store persistently in an STM32G030 without consuming a 2K flash sector. Obviously one option is OTP, but I'm curious about the Fl...
I am migrating a project from STM32F373 to STM32G473. I can program the new part successfully, but I don't see PWM . The PWM values are written in user created code and I can read them back via the STLink, so I know that the part at least begins runn...
Hi all, I have been working on a project that involves using a MAX7219-based 4 x 64 LED matrix display and I experienced various issues regarding how properly control what is being displayed on the board. I used 3 different libraries as a foundation ...
