Resolved! STM32h743 max FMC SDRAM clock 100MHz?
Hi,I found this in datasheet But we config SDRAM at 120MHz, because we are running at 480MHz.(480MHz / 2 / 2 = 120MHz).I am thinking the datasheet is for STM32H7xx 400MHz, because when I config SDRAM at 120MHz, the system works fine without issue.Doe...
Can STM32 force CAN_TX pin to CAN_RX pin and CAN_RX pin to CAN_TX pin?
Hello, I need some help. I have problem about CAN bus. I connect the wire to the header pin. It swaps between CANH and CANL. Can STM32 force CAN_TX pin to CAN_RX pin and CAN_RX pin to CAN_TX pin? If not, do you have another solution?In my case, I can...
STM32F407VE sector 4 erase problems

What does "Bit-Band Operation of Different Data sizes" mean?
Hi, I am reading the book <<The Definitive Guide to the ARM Cortex-M3>>, and I see some descriptions below, but I really don't know what it really means. Could you explain it to me?Thanks very much.
hcan1 not working while hcan2 does work with same settings
I'm working with a custom STM32F105 board with two similar CAN circuits but CAN1 is not working.I use STM32 HAL with this custom CAN lib which handles configuration and buffering.It was working before with the same hardware but I can't get it woking ...
Is there a way to detect if running on a STM32f103VC as opposed to a STM32F101VC.
Customer has fitted both to different rev boards and wants to detect the hardware rev based on the processor type that was fitted. both run the same firmware without issue. I'm looking for a way (in firmware) to detect which processor is fitted.
STM32H562 - application note/out of box example for SAI with PDM mic
At the moment, we evaluate feasibility of STM32H562 for our application. Our application is using PDM microphones. However, STM32H562 has SAI interfaces but no DFSDM filters.Is there any out of box application example /application note for PDM micro...
How do I check the MMC or SD cards before the card identification process in STM32?
In the RM0090 Rev 19 document of the STM32, there is a card identification process explanation, The card identification process differs for MultiMediaCards and SD cards.It seems that the card identification process is different for MMC and SD, but si...
