I'm using triple interleaved ADCs to fill a buffer (6000*16bits) in circular mode via DMA,and I needed to know when I wanted to read the whole buffer via another DMA request and write it to a second buffer to be processed offline later would I need t...
I'm trying to port some code from a Discovery F7 Board to the dual-core H745 Nucleo board and I'm going to make use of the following peripherals:ADC, DMA, SDMMC, Ethernet and UART. I have this all working on the Discovery board but I'm having trouble...
I'm using STM32F031K6Tx in my design. I have given provision for both UART (PA9/PA10) & SWD (SWDIO/SWCLK) for programming MCU using test fixture in the factory. Either one will be used1) Is BOOT0 (0 = Main Flash Memory; 1 = System Memory) needs to be...
Hi, I am using bno055 with stm32f4 discovery board. I am trying to read chip ıd. HAL_IsDeviceReady function return HAL_OK but I can't read chip ID. Why is that? I tried to write my code or using library. Here is the code and stmstudio's return. (In c...
Nowadays. i debug the uart1 under linux with arm-none-eabi- cross compile.Now i meet a problem，i config uart with 115200 baudrate and 8 databotlen 1 stopbit none parity.use Hsi for SYSCLK APB1 and APB2 CLK BOTH 36MHz. I can receive data from the chip...
First, I would like to know if this code is correct to setup SPI to re-transmit by DMA again. GPIOA->BSRR = (1<<5); // start DMA1->IFCR = 0x0FFFFFFF; // reset status DMA1_Channel3->CCR &= ~( DMA_CCR_EN ); LL_DMA_SetDataLength(DMA1, LL_DMA...
Hi, i am currently working on a driver for a Chineese IC. The manufacturer recomends implementing SPI protocol over an FPGA, but for cost reasons we would like to use a MCU.The SPI protocol that the chip uses has the following configuration "Chip SPI...
Hi guys, i am going to connect 2 STM32 via 3 SPI busses for high speed data transfer throughput (STM32H7 <-> STM32G4).The STM32G4 will be Master and the SCLK-frequency will be 84MHz - i will use the associated pins in the highest speed mode setting.I...
Deat ST Hello,This my first question to you in this forum.Does ST has peripheral examples using HAL library or standard lib for STM32f4?I am installing the packs from the pack installer from Keil.Could I adapt examples for my STM32 if ST provide a g...
I'm working on the STM32H7 series, and in my scenario the data to be written might be the erased-state byte (0xFF) all over the flashword. In this case I'm unsure whether or not the ECC may change.What is the idiomatic way of checking if the bytes ha...
