MEM-to-MEM transfer using DMA (SRAM to FSMC/FMC)

Hi,As far as I remember, I've read something about that a while back. I was wondering if I can send data to a memory-mapped device (FSMC/FMC) in a continuous loop a byte per iteration using the DMA peripheral. Thanks

STM32F10x entering standby mode fails occasionally

Posted on October 28, 2016 at 02:11We use PWR_EnterSTANDBYMode library function to enter the standby mode. I have added line to enable WKUP pin. The STM32 enters standby mode most of times. But, sometimes(once in 25 or so times), it just reaches the...

can I use one timer to interrupt another timer (start and stop)

I want to generate 1 Mhz with one timer but I want to stop it for 1 ms and then generate for 5 ms.I see that there is instruction HAL_TIM_Base_Start_IT looks like I can start and stop one timer with anther, I am using Cube MX and keil.

STM32L486 mcu used as Master SPI, Zigbee device as slave. What configuration of SSM and SSI should i be using?

I am going through an existing implementation, where my MCU's(STM32L486) SPI1 (PA4(NSS), PA5(SCK), PA6(MISO), PA7(MOSI) is used as master, the slave device is a zigbee stack.Currently the master's SSL is configured as Software managed, (SSM=1, SSI= ...

In STM32L100 sleep mode, some sets consume more current. My standard is below 60uA. Defects consume over 100uA

Interrupt Disable, ??/

Hellousing HAL libraries is it possible to disable for a short time an external interrupt pin ??I have had a look in the HAL GPIO files and can not see anything usefulJust want to disable while a trigger a debounce timer, there must be a way of just ...

Stm32F3xx Flash read and write uses but focussed around byte size operations

Hi ,I ma looking at using the internal flash for EEPROM emulation, using Atolic and STM32F302ccI have read the aplication note on eeprom emulation and quite a few stackoverflow discussion as well as a few ST community posts which seems to focus arou...

I2S on STM32F446ZE micro controller to check(test) microsemi ZL38063

Here I am trying to generate a simple example of sine wave to pass over I2S and just send the data on ZL38063(slave) using STM32F446ZE . Clock is working fine @1.5Mhz and WS @48Khz and also getting PWM data on SD line. I am not able to hear any kind ...
