UM2411:Caution: The I/Os of the STM32 microcontroller are +3V3 compatible instead of 5 V for ARDUINO ®Uno V3This mean can not conect to Stm32h747-Disco with pines for uart to arduino directly o no ? If hay problem with this how to send data o solve t...
Hello, I have the STM32G474 Discovery Kit and am just attempting to get a blinky LED program to work on it for right now. In the STM32CubeIDE, I imported an example, was able to get it to build correctly (after changing references from caddr_t to voi...
If I register a callback function for GPIO EXTI and I have EXTI on multiple ports for the same pin (e.g. PA0 and PB0) how does the callback distinguish between the ports when the event triggers?
Hello I have set the timer7 for 1 minute interrupt. It is working at every minute as expected. But the interrupt is also triggered as MCU is reset. I have set global counter for increment in timer7 callback. As soon MCU is reset , Timer7 callback is ...
Hi,a footnote(4) in STM32H7 reference manual RM0468 Table 56 regarding the maximum allowed frequency for ADC says"With a duty cycle close to 50%, meaning that DIV[P/Q/R]x values shall be even".Does this recommendation apply to the actual DIVXx regist...
Hi, I am trying to synchronize a SPI Block data transfer between two MCU's (Ti MSP430 Master, STM32G0 Slave). The idea is to use the DMA to transfer the data to memory and use the DMAMUX to Sync with a timer. For demonstration, the data is transmitte...
Hi,I was able to get a frame(result attached below) from Nucleo-WB55RG by controlling HSYNC and VSYNC with the help of EXTI. However, I have faced some pixel loss(pixels from the white color) at the beginning of each HSYNC. I suspected that the issue...
I am trying to implement an EEPROM driver which uses DMA. So far, I can implement polling and interrupt version. HAL_SPI_Transmit_DMA works OK, but HAL_SPI_Receive_DMA returns HAL_BUSY, so even the first reading process seams OK, it actually doesn't ...

LPUART1_TX - PA2LPUART1_RX - PA3I'm having trouble testing because I'm getting frame errors by UART1.My PCB didn't design any circuit for PA2 and PA3 because the IC that connects to the MCU's UART pin uses 3.3V TTL communication.However, using the HA...
