Posted on October 22, 2016 at 04:27 I am not sure if this is a bug fix or an enhancement. I am developing on a proprietary board using the STM32F7 series processor. I have a device connected via USB using the USB Host Library. This particu...
I am a beginner using the Nucleo-F334R8 with Keil and STM32CubeMX.I want to read ADC data with DAC. The ADC is from a potentiometer, and I will read the DAC using an oscilloscope. I am using the program below so that when I run it, it will generate t...
HiI use STM32U575I-EV.I want to periodically read data from an external SPI device without CPU.The SPI device will emit a data ready signal(active low gpio), so I want to use that as a trigger to read the data.Ideally, I would like to perform multipl...
Hi,i'm using a STM32L031. In my code i first initialize the MCU (FLASH, CLOCK, INTERRUPTs, GPIOs), start the LPTIM (running on LSI), then slow down the MSI clock, start the timer22 for PWM and go into low-power sleep mode. When i let the program run...
I'm currently testing low-power applications on the NUCLEO-U545RE-Q board, which involves using an SSD1306 OLED display and a BME280 MEMS atmospheric sensor, both interfaced via I2C1 and I2C3 at 1 MHz. The FCLK is configured to 160MHz. Clock source i...
I have a NUCLEO-F103RB and I am trying to communicate with my AHT10 sensor. I understand the basics of I2C but i'm a newbie to stm32. For some reason when i do HAL_I2C_MASTER_TRANSMIT it seems to return a failure but HAL_I2C_MASTER_RECIEVE doesn't re...
Hi,I'm using the software EEPROM to save a variable to flash that is being updated during run time, that I would like to read in case the system resets. Whenever the system resets, for stability, it writes a line of "dummy" 0's to the next available ...
Hi,I have been working on NUCLEO-U5A5ZJ-Q EVK to setup as a USB VCP device with the support of STM32CubeIDE. I got an example from the ST repository. Its using the Azure RTOS USBX stack instead of STM32 USB Device stack. I am not very much familiar w...
I am trying to implement an IAP function on stm32h563 with Keil. I have a bootloader and image A and B, all running on flash. Image A and image B are running on bank 1 and 2. When i was running image A and updating image B, new image B is successfull...
I am using stm32f779I eval kit. I am using example UART_HyperTerminal_DMA by en.stm32cubef7.I am trying to implement UART in DMA mode to transmit a simple string.So I have used CubeMX to generate the code and I have configured UART1 TX DMA in normal...
