STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on November 25, 2016 at 14:56 Hi, We are using STM32F401 MCU, definition of SPI1 Initialisation function/api is attached, we need to make MOSI signal to be high (default it should be high), if no communation between master and slave.ple...
Posted on March 23, 2017 at 11:40Hello,I would like to ask you for an advice regarding the CAN messagesfiltering. I am not sure whether I understand the filtering and maskingin right manner. I have following settingsCAN_FilterConfTypeDef filt;filt.F...
Posted on March 24, 2017 at 17:58 Hi, I'm semi experienced with STM32, have been doing a lot of things. This issue is totally new to me: I'm trying the simplest thing ever, basic SPI, set as master, chip select managed by myself. Transmit works, c...
Posted on March 23, 2017 at 16:44Hi! I've just recently checked http://www.st.com/content/ccc/resource/technical/document/application_note/b9/9b/16/3a/12/1e/40/0c/CD00167594.pdf/files/CD00167594.pdf/jcr:content/translations/en.CD00167594.pdf that is...
Posted on March 26, 2017 at 18:55 I use SPI and DMA transfer. I use the following functions: HAL_StatusTypeDef HAL_SPI_Transmit_DMA(SPI_HandleTypeDef *hspi, uint8_t *pData, uint16_t Size); HAL_StatusTypeDef HAL_SPI_Receive_DMA(SPI_HandleT...
Posted on March 22, 2017 at 13:14Is it possible to use DFUSE to update via USB if I have an external phy? I'm using an STM32F777. I do have a 25 MHz external crystal for HSE.
Posted on March 23, 2017 at 13:47I am using TIM2.CH2 input compare. No other interrupts are activated except TIM2.CH2. In TIM2_IRQ handler all IC bits except CH2 are set. Why?Using STM32Discovery on IAR. I expect TIM2_IRQ to fire up on trigger from ...
Posted on March 14, 2017 at 17:04Hello everyone!I was forced to move my project to HAL Libs for bunch of reasons beyond the scope of this discussion, and ever since, I ran into problems getting the SPI to work properly. I spent a tremendous time try...
Posted on March 25, 2017 at 09:27Hello everyone. I am using STM32F401RE Nucleo Board. I want to communicate with PC through USB CDC Virtual COM Port. I was following an instruction for STM32F4 Discovery and then I realized that my Nucleo Board didn'...
Posted on March 23, 2017 at 20:24STM32F437 processorI have no experience using the stm32 timers with DMA so I wish to solicit suggestions before banging my head against the wall.I have set up a counter using an ISR to count pulses (RPM) and it works...
