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...
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...
I made a mistake a few days ago that resulted in my program erasing part of itself. \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\I'm doing a bare metal bootloader on a STM32F407VE and ha...
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.
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 ...
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.
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...
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...
I'm using STM32F446RC controller CAN BUS 1. Trying to operate CAN BUS at 1mbps speed when using 100kbps bit rate it is working fine but not at 1Mbps bit rate. Is there any solution for this.
