Why stm32H743zi has longer access time to GPIO interface?

I have two nucleo-144 boards, stm32F767zi and stm32H743zi. Both cortex-M7, pin compatible, and pretty close in AHBx (GPIO) clock, 216 vs 200 MHz.Testing TFT LCD display library, that required fast 8-bits access to the LCD data bus, I discovered that ...

RTC ALARM A Stops working after Mid-Night

I'm using STM32L152RE with FreeRtos for our project. We use RTC HAL library to handle the Calendar alarms. I'm in a strange situation where the RTC_ALARM_A does not generate an interrupt after 12 midnight. The current system is setup to generate an...

Can STM32 read external FIFO through the FSMC interface?

I want to use FSMC to read external FIFO implemented in an FPGA. Since there is no mode of FSMC that can match FIFO interface exactly, so I want to use the modified synchronous multiplexed PSRAM mode. The plan is like thisA[25:16]: Ignored, don't ...

Cheap Evaluation Board with SD-Card

Is there a cheap eval board e.g. Nucleo-64 with an SD-card reader. Also A cheap shield for Nucelo-64 with SD-card socket would be ok.Its for a simple logger application but I am hesitant to make a board for only a uC Sensor and SD-Card.
