Hi,I am using STM32G474RET6 controller and would like to send and receive data in classic mode. I have configured all necessary parameters using cubemx but the hard fault occured when I call this function HAL_FDCAN_AddMessageToTxFifoQ(&hfdcan1, &TxHe...
Hello,I'm trying to port the example found here: https://blog.embeddedexpert.io/?p=1680 to NUCLEO-U385RG-Q.The example in the link is for STM32F411. I've successfully tried the example.Verbatim port of the code leads to USEF being set in GPDMA_C0SR.T...
I have designed a board with a STM32H573 and a KSZ8081RNACA PHY. As soon as I enable ETH clocks the ETH_DMAMR:SWR bit gets set.Verified:1. The 50 MHz clock from the PHY is present and stable (oscilloscope) at PA12. GPIO PA1 is configured for AF11, NO...
I used the example code in RM, and room temperature is arround 31℃，the ADC value is 10644, calculated temperaure is 4127, does it means 41.27℃？what will happen if minus temperature?/* Temperature sensor calibration value address */#define TEMP130_CA...
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...
