Hello, I am using a STM32L471QGI6 MCU and its reference manual (RM0351) is:https://www.st.com/resource/en/reference_manual/dm00083560-stm32l47xxx-stm32l48xxx-stm32l49xxx-and-stm32l4axxx-advanced-armbased-32bit-mcus-stmicroelectronics.pdfRegards the "...
Hello,my STM32 is running with 1.8V and is connected via I2C to another chip. The I2C has an level of 3.5V (connected via pullup to 3.5). I now have communication problems. Is there any limitation for maximum voltage for the high level of I2C on STM3...
Hello all! My name is Matt and I am a university student studying EE. For school, I recently designed a board with an STM32405RG MCU and BMI088 IMU. Part of the project is gathering data from the gyroscope and processing it every time step. My origin...
Hello!I am writing a program and am still on the code generation phase. I am having a weird issue where the code runs, but gets stuck in the initialization phase for the SDIO (MX_SDIO_SD_Init). If the SDIO is commented out, the program gets stuck in ...
I have an 1.8V STM32 and an 3.5V MAX31865 which are connected via SPI, I used 10k Ohms pullups on data line to 3.5V. Now the problem is that communication dosen't work. When I increas STM32 voltage to 3.5 V everything is fine. Is there an limitation ...
Hi,I am using STM32G474 Nucleo board and try to use TIM1_CC_IRQHandler. I am using TIM1_UP_TIM16_IRQHandler to check certain conditions and then I'll enable the CC1IE bit in TIM1->DIER register.I configured TIM1 as Center-aligned PWM mode.However, I ...
Hi,I'm running into a very strange issue with the CAN module. When enabling ABOM on CAN2, some but not all of the FIFO1 RX interrupts are missed. As soon as I disable the ABOM setting, everything works as expected. Has anyone seen this behavior be...
Hi--I/m pretty stumped. I am trying to implement a odd parity configuration for USART1 in an stm32L452RE micro. I've confirmed without parity the usart behaves as expected at the needed baud. When i introduce parity into the code and sniff the data o...
Form, Fit and Function Alternate for Part STM32F070RBT6 as this is not procurable at the time, we need an alternate that can fit into design without any software or hardware modification.
HiI'm using the HAL_SPI_TransmitReceive_DMA to write to an external Flash. On a delte command for the external flash I need to wait for until the busy flag of the flash is zero. So I use this function to check the busy flag. spi_read(&command, sizeo...
