STM32 MCUs Embedded software

STM with Fiber optic PHY.

Hi all, I'm looking for an STM microcontroller based eval-board/reference design, using only one Optical Phy. I would also like to have schematic and firmware support [preferred SPL] for the above requirements.Thanking with regardsAatif S...

HAL_Delay API is providing more delay than expected

When HAL_Delay(420) is invoked for 420 milliseconds delay it is providing 438ms of delay when measured in CRO. void SysTick_Handler(void){  HAL_IncTick(); }

USB otg automatic role switching device cdc - host msc

Posted on October 17, 2014 at 13:12Hello I have a question about USB OTG with STM32F4 discovery. I have a working application for cdc device mode and in another project a application for msc host mode (from STM32CubeF4 V1.3.0). Is it possible to con...

UART Half Duplex: How to get DMA working for both RX and TX on STM32F303CC?

I am using UART1 in half duplex mode and DMA works for TX, but I cannot get it to work for RX (after calling HAL_HalfDuplex_EnableReceiver). Here is my initialization code: __HAL_RCC_GPIOA_CLK_ENABLE(); m_GPIO_InitStructTX.Pin = GPIO_PIN_9; ...

STM32L073 - Jump to Bootaloader from user code

Hi,we are developing an application on a STM32L073RZT, that needs to jump to the embedded bootloader frim software, since we can not use the BOOT0 pin.I tried to write a code that jumps to system flash, using the NUCLEO-L073RZ board. In order to achi...

i trying to download the .bin(binary) file from sim module to SD card using fatfs file system,

but after download to sd card the bin file size is lesser than the actual bin file & also its adding "0d" in between . Then how to download it properly to sd card.
