Resolved! HAL and GPIO EXTI
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?

Resolved! Timer interrupting on MCU reset
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 ...
Resolved! PLL clock division in STM32H7 for fadc_ker_ck
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...
Resolved! Synchronization of SPI and DMA for Block data transfer using DMAMUX
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...
Is it possible to control HSYNC,VSYNC with different Peripherals other than EXTI?
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...
HAL_SPI_Receive_DMA returns HAL_BUSY
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 ...

Resolved! STM32L031F6P7 UART1 Frame Error
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...
