Communication problem with SPI NAND flash memory (STM32L4, QSPI)
I am trying to use an external flash memory (TC58CVG1S3HxAIx) with NUCLEO-L476RG board. I can’t get the QSPI to work. I used STM32CubeMx to configure QSPI: void MX_QUADSPI_Init(void) { hqspi.Instance = QUADSPI; hqspi.Init.ClockPrescaler = 255; ...
STM32F413 I2C. ACK from slave is not recognized.
Hello everybody,I am having an issue when I try to establish a communication with the NFC chip M24SR64 via I2C. After I have sent the address (0xAC), the flag AF is set, indicating that the ACK of the slave was not read. However, I can see the ACK fr...
Resolved! Possible to trigger timer events from software on STM32F4?
I am working with the STM32F4 family. External interrupts have a register called EXTI->SWIER that makes it possible to generate external interrupt from software. Do the timers have something similar, a register that I can use to generate timer interr...
HAL_RCCEx_GetPeriphCLKFreq (RCC_PERIPHCLK_USART2) function
Hi, I'm working with the stm32f030c8 processor and I'm trying to use the MY_VAR = HAL_RCCEx_GetPeriphCLKFreq (RCC_PERIPHCLK_USART2) function;But in the stm32f0xx_hal_rcc_ex.h file there is no definition of RCC_PERIPHCLK_USART2 for the stm32f030c8 whi...
program on UART_EMUl
I am doing softuart(uart emulator) EXTERNAL INTERRUPT in that i can transfer the data and even i can Receive data also but in that i am facing one program while receiving data (if i type first char is 'A' 'B' and 'C' so on i am getting last but one c...

STM32L4 not staying in STANDBY
Posted on July 02, 2018 at 19:13Hi, I am working with an STM32L4. I'm trying to put it into STANDBY mode, and wake it up using a WKUP pin. The issue is that the first time I go to standby after POR, the system wakes up immediately, though I'm s...
STM32F4 I2C communication
Hi, I am trying to establish I2C communication b/w I2C1 and I2C2 on Stm32f4-discovery. I used CubeMx to generate code for standard mode with the following addresses.I2C1 = 0x5I2C2 = 0x7In the while (1) i added the following code.resp = HAL_I2C_Master...
