Steps to have external SDRAM work properly!

I'm editing linker and startup files according to the example "FMC_SDRAM_DataMemory" but i con not access SDRAM. In example, it has only 2 regions as FLASH and RAM but we have 5 regions as FLASH, DTCMRAM, SRAM1, SRAM2 and MEMORY_B1. Also how can an i...

STM32F051R8 works when in debug mode and not in normal power mode

The device used to work fine even when not in debug mode. However, after some tweaks in the clock configuration, the device all of a sudden stopped working even the simplest of the program like toggling a GPIO pin. The same program works well fine in...

In full duplex mode of spi, observed same data on MISO and MOSI when we are only receiving data from ADC.

Hi,We are using ADS1292 to get the ADC samples and we had successfully read the 7000 sample with the help of imx6 processor, STM32F4 discovery board.But now our project requirement changed and we have to use STM32F030R8 controller. In initial stage, ...

On STM32F4 discovery board we got accurate 7000 adc sampes but unable to read 7000 adc samples using stm32f030r8 using SPI. Please provide your inputs.

Can't reset I2C in STM32F407 to release I2C lines

Posted on January 12, 2017 at 08:18I am using an STM32F407 on a customer board and have trouble with the I2C handling.I am using the latest HAL HAL_I2C_MasterTransmitIT and HAL_I2C_MasterReceiveIT to poll data from a sensor.The problem is that after...

Can i read BOOT0 pin state from program?

Hello.Can i read state of BOOT0 pin in STM32F030F4P6?My uC always turn on with BOOT0 GND, but i need to have dual purpose pin BOOT0 and have possibility to read only state of this pin.

How to recover bricked STM32F051R8? (STM32F0 discovery board)

FMC Timing registers can not be written!

Im working to use external SDRAM for STM32F746DISCO board and configuring associated FMC register. When ia start to debug i see that all of SDTR (timing) register bits are valued as F. I can write to SDCR and SDCMR registers but can not write to timi...

Embedding USB Debug Interface on a board

We are preparing the design for a board that will be sealed in a system, so connecting a standard USB debugger to the system isn't going to be feasible. We would ideally like to place a circuit on board similar to what the various evaluation boards u...
