I have an odd issue. I am setting up a timer compare channel for a 5ms delay in the future. I set the counter to 0, set the compare value to 5ms in the future. The compare interrupt does not occur, until the timer wraps all the way around and pass...
Hi all,I'm working on a very low power custom board powered by a STM32C011D6Y micro controller. I must read an ADC input routed to F1 ball (PA3, PA4, PA5 or PA6) but I'm measuring some strange power consumption related to the input voltage on the pin...
Hi there,I am using the full featured USART in LIN mode. The start of a LIN packet is signaled by a BREAK condition. The next byte is the SYNC (0x55). After the BREAK is detected, I enable the receiver timeout so that if the SYNC (0x55) is not receiv...
Hello everyone,I’m working on a project where I am using STM32F407 and I’m trying to establish USB communication between my STM32F407 Discovery board and a PC. I have configured the board for USB_OTG_FS in STM32CubeMX, and I’m trying to use it as a V...
Hello,I am trying to build a part of the project.I want my three microcontrollers to communicate with each other via CANBus.What i am trying to achieve in this part is reading the digital sensor value from my hall effect sensor and sending this infor...
Hello,I noticed in the document RM0368 (Rev 6) for F401RE the SPI Register map (Table 93 page 611) is missing the SPI_CR2 register.I came across this topic, created in 2021 and now closed :https://community.st.com/t5/stm32-mcus-products/error-in-rm03...
Hello STM32 Community,I'm trying to implement CAN communication on my Nucleo F446RE board and I'm facing some challenges getting it to work properly. I've attached screenshots of my .ioc configuration and the auto-generated code from STM32CubeIDE for...
Hi everyone, I'm trying to generate a sine wave using PWM output updated by GPDMA transfer on an STM32H5 device. I'm following this tutorial:STM32 Change PWM Duty Cycle With DMA For Sine Wave Generation However, when I try to implement it with STM32H...
Can we keep VDD33USB keep NC if USB feature not using In STM32H753ZIT6?If kept NC what may go wrong?
STM32World Rant #2 - MYSTERIOUS UNKNOWN MCUJust a short rant about the MYSTERIOUS STM32F402. This MCU does NOT exist in ST's catalog, and yet you can readily buy them in China. In this video I will go through the datasheet, find a comparable MCU whic...
