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...
Hi Folks,I'm having an issue with just reading and writing new values to the RTC. I'm using a custom board that contains a 32.786Khz crystal and in CubeIDE the LSE is setup properly. I also have a battery connected to Vbatt,I'm using the following to...
As per the title: I am using Timer 2 for a PWM. Channel 1 and 2 work just fine, but Channel 3 and 4 won't output anything. Created the project with CubeMX. Tried enabling all 4 channels with all the same values except pulse (CCR) and probed the outpu...
I have an Arduino Giga (STM32H7) and I'm using the timers to generate PWM's. Everything's working fine, programming is no problem, but I cannot come up with a way to implement what I want. I included a simple visual to describe what I want the output...
I have a couple dozen of custom boards with STM32G4s on them. These boards are all 'identical' and the software being loaded on them is the same. BOOT0 pin is currently floating so on my initial load I held it to ground and changed the option bytes v...
