Hi, I am encountering an issue with mounting the SD card in 4-bit mode on my STM32F756ZG microcontroller. Despite using the BSP driver (bsp_driver_sd), the SD card fails to initialize and mount correctly, resulting in an initialization error and the ...
Basic setting of USART2: DMA Transfer and receive via interrupt as RS485.As long as only DMA transfer is ongoing, all will be ok. At first time a receive interrupt will occur, the transmit will trigger an interrupt, even though no TXEIE is set. This ...
According to the description of Section 7.3.2 "Error code correction (ECC)" in the RM0456 manual, reading the data at address 0x0BFA1F80 is supposed to generate an NMI interrupt.However, when I tried to read the data at this address, no NMI interrupt...
I am using the hspi1 peripheral in HyperBus mode on an STM32U5G9 processor.I used STM32CubeMX to configure the hspi clock to 160 MHz, generated from the SYSCLK. The hspi is configured with 0 Clock Prescaler with the intention of having an external 1...
Moved from MPUs forum.Hi, i must Use a Single Port Gigabit Ethernet PHY that have a RGMII Gigabit Interface to connect a RMII 10/100 MbitEthernet MAC interface of the STM32H563VI MCU. Do you think it is possible to connect a Gigabit PHY chip to the ...
I had a program tested and running on a NUCLEO-F072RB for some time. Later I custom built my own PCB (using a STM32F072RBT6) and flashed the exact same code onto it using a STLINK-V3SET and the program did not work. I had no idea on why the program ...
Hi, I need help for estore coupon. I got an email the redeem free board with exclusive code on ST estore. After applying the code, A message "Your cart is not eligible for this promotion. Ensure that you are logged in and items match promotion ter...
First time designing for ST microcontrollers, so I thank you for your patience. I see by the datasheet that USART1 can be used as a LIN bus directly without a LIN bus transceiver, but I can't find any examples of how the hardware is implemented when ...
Regarding LL_AHB1_GRP1_EnableClock, after setting bit in the function, it is read to "tmprg" and cast to void type. What is the reason for reading?__STATIC_INLINE void LL_AHB1_GRP1_EnableClock(uint32_t Periphs){ __IO uint32_t tmpreg; SET_BIT(RCC->AHB...
