I just solved a bug in my software, and can't quite understand how it happened. My code is a built in hardware test for our board, and a bootloader, which communicates with a serial bus and downloads different compoents to different memories. One o...
Hello I have DMA ADC and store data in uint16_t bufferI need to copy these values to input buffer to arm_rfft_fast_f32 function;the function should also cast ushort to float void copy_adc_to_input(uint16_t * int_buff, float32_t * float_buff, uint16_t...
FLASH->ACR |= FLASH_ACR_PRFTBE; /* Flash 2 wait state */ FLASH->ACR &= (uint32_t)((uint32_t)~FLASH_ACR_LATENCY); FLASH->ACR |= (uint32_t)FLASH_ACR_LATENCY_2;
Hi, everyone,I have been struggling with an issue for sometime. Upon reception, occasionally, a Byte is received with an error in which the most significant bit is received as a '1'. For example, if 0x55 (0101 0101) is sent, 0xD5 (1101 0101) is rece...
I'm not having any time critical routines so I'm hoping of using all of the MCU's 1MB of RAM for data. As I understand from the RM, RAM is organized in a several banks. Can it be used as a continuous chunk of 1MB for data?
Hi, I am using NUCLEO-F302R8 EV-board. I want to configure the CAN as:use all 3 transmit mailboxes with different mailbox IDFiltering ID number for each mailbox Receive three complete message for each FIFO with filter ID numberBy following CAN settin...
i used stm32f031 as master & slave, NSS is alwasy low, connect MOSI and MISO. the master transmit datas successfull then changing the master direction to receive data( SPI->CR &=~SPI_CR1_BIDIOE), at the same time slave recv and try to transmit data...
Dear st team,What are the major changes in STM32F767BIT6 and STM32F777BIT6?is STM32F767BIT6 code works in STM32F777BIT6?
HAL_Init(); SystemClock_Config();// Configure the system clock to 180 MHz __HAL_RCC_GPIOA_CLK_ENABLE(); GPIO_InitStruct.Pin = GPIO_PIN_13; GPIO_InitStruct.Mode = GPIO_MODE_INPUT; GPIO_InitStruct.Pull = GPIO_NOPULL; HAL_GPIO_Init(GPIOC, &GPIO_InitStr...
During testing an SPI DAC (TI DAC8563) on an STM32F446RE (where it works) and on an STM32F767ZI (where output is always 0V), I noticed a different SPI clock waveform.In F4 you have three "8 pulses" signals from CLK (the message from MOSI is 24 bit), ...
