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...
Posted on July 10, 2014 at 07:10 Hi, I'm trying to establish SPI communication between PIC18F2580 as master and STM32F4 Discovery as slave. Using logic analyzer,I found that PIC and STM32F4 actually sending bytes (PIC's MOSI and STM3...
Posted on October 02, 2013 at 10:05Maybe it'sread bydevelopers from ST. I had two ideas for improvements - Somehow graphically distinguish outputs that are 5 volt tolerant - Add user defined (label) tag in which the user can observe what signal is ...
Posted on July 08, 2014 at 19:01Will not allow configuring both USB and CAN at the same time (forces both to PA11/PA12). Trying to configure USB on PA11/PA12 and CAN on PB8/PB9. CAN shows up in override list for PB8/PB9 but pins turn orange and stat...
Posted on July 08, 2014 at 08:25Hello;I am working on stm discovery. My aim is get output from speaker. I did it in main function. but i want to use SPI3 interrupt for send data. My codes in below. The code does not go to interrupt. I put breakpoint...
Posted on July 09, 2014 at 07:51For now, I need to do a simple benchmark of memcpy. Here, it's pseudocode.#define SYSTICKS_REG 0xE000E018uint32_t *get_systicks (void){ return (uint32_t *) SYSTICKS_REG;}measure_start = *get_systicks ();for (int j ...
Posted on June 13, 2014 at 20:42Hello,I am confused by a DMA2 ISR and TIMER ISR conflict which is occurring in my project.The project is based upon the FATFS SDIO example project provided with the STM32F4Discovery PCB.I have had no trouble whatsoeve...
Posted on May 27, 2014 at 09:14Hi, I am facing an issue to configure system tick for STM32F407VGT6 discovery board. if (SysTick_Config(SystemCoreClock / 1000) is given in example to configure system tick for 1 milli sec. This board runs with 168MHZ....
Posted on July 07, 2014 at 16:20Hi!How can I tell the STM32F303 bootloader to run application code from flash memory? After reading AN3155, I tried the following byte sequence (''>'' indicating bytes sent to the serial interface, ''<'' bytes receive...
Posted on July 09, 2014 at 11:55Hi, I'm running the example code to try to program the flash memory. This starts:void WriteFlash(void){ /*!< At this stage the microcontroller clock setting is already configured, this is done through System...
Posted on July 09, 2014 at 11:20Hey guys,I'm using STM32F4 discovery board and I have some problems to communicate between MCU and PC using MSC BOT protocol.I would like to exchange data from my MCU to my PC and my PC to my MCU.I'm using the library...
