I am trying to interface a Nucleo-f439zi board with an external AS6C4008-55SIN SRAM chip through an "Arduino HAT" style board I am working on. Below is my current schematic.In the chips manual, the table below is shown for using FMC to access externa...
I want to interface a Nucleo-H743ZI2 board (MB1364E) with a memory chip using STM32's FMC.In order to do this I need to free up the following 4 pins, to be used by the morpho connector:PE1, currently yellow user LED, needed for FMC_NBL1.PD8, currentl...
I have used CubeMX to configure the HAL comparator driver to trigger an interrupt on the rising edge only, however the interrupt seems to occur on both edges. I checked the EXTI registers and everything seems correct. I then thought that my voltage s...
simple 3 Button Touch Key application using TSC on STM32L431 goes wrong when VDD power supply drops from 3.3V to approx 3.0V (just above BOR level) then recovers to 3.3V.All 3 Buttons are read back as active from this point on. Has anybody experience...
Dear Community,i'm working on an 4 Slot SAI Interface with an STM32G4 Series MCU. The FrameSync signal is kind of slow (~2kHz) so i want to use the Receive_IT() to throw an interrupt when 4 Slots (32Bit each) has received. So after starting the ADC H...
I bought a stm32f429i-disc1 board and I want to learn how to communicate to stmpe811 with I2C protocol, now I'm a little confused. According to stmpe811's data sheet, its address is 0x82 because its A0 pin is connected to ground, but board's schemati...
Grettings,Can the FMC be configured to handle a similar configuration?I have an SDRAM that has byte enable pins to the upper and lower bytes (Disable -> High Z), but no pins available to map the 16 bits. So, at the moment I'm working with half the me...
Is there any information about long term stabiliy of the internal high speed oscillator (HSI)?
I am exploring on controller selection. And need to know how much power is consumed by STM32F7 series controllers assuming that very few peripherals are used.It will have ADC, SPI, Timers, FLASH and FRAM access.So, wanted to know how much power it wi...
