Posted on January 19, 2017 at 14:26It seems that CubeMX is getting better about retaining some of the Keil project settings upon regeneration of the code. There is an issue that I just came across. We sometimes use multiple named Project Targets i...
Posted on March 30, 2017 at 10:47Hello,I would like to save application data into flash area in order to be preserved, so data should be there when removing voltage and applying voltage to device again.Which is the best option for this purpose? How ...
Posted on March 29, 2017 at 17:47DearI'm new with STM32 and ARM. I am using the nucleo STM32F103RB and using STM32CubeMX and HAL libraries. I want to save 10 to 100 uint32 size register in the flash that will be loaded on startup to have the correct...

Posted on March 30, 2017 at 08:07Hello, I have eMMC card (8bit SDIO interface), but I think it will be the same situation with SD card. All I want to do - is to make Fat partition for user data storage(video, photo and etc. - it acts as usb flash dr...
Posted on January 20, 2017 at 12:39hellostarted STM32CubeMX and selected the stm32f051k..,then added the i2c peripheral and then selected the configuration->connectivity->i2c1 and finally gpio settingsnoticed that the GPIO Pull-up/Pull-down drop do...
Posted on March 29, 2017 at 16:35I am sure there is a simple answer to this question. DMA is accessing memory. When would there be contention for memory if the processor tries to access memory? Is it when the addresses are the same or is it when blo...
Posted on March 29, 2017 at 12:19Hi,I would like to use some external DACs and ADCs connected to my STM32F769 MCU.The DACs (AD5512) and ADCs (ADS8320) have an interface with : + DIN : data input + CS : chip select + SCLK : clock for the data s...
