SPH0645LM4H-B interface with STM32L476RG on SAI
Hi,I am trying to interface SPH0645LM4H-B mic sensor with STM32L476RG on SAI.I have configured the SAI2 block A with following configuration.Master clock :- 2.826 Mhz Sampling rate :- 44KHZ//////////////////// PLL configuration //////////////...
Periodically trigger DMA by means of timer (without interrupts) - is it possible?
Hello. This is a question about possibilities of STM32F7 or STM32H7 MCU series.I have a sensor connected to the SPI bus interface. I need to periodically poll it with more or less constant period (which is 250 us). Using any interrupts is forbidden. ...
"System Workbench�?(SW4STM32) printf redirection not work
Dear AllI would like to redirect printf output to UART.It seem very simple in this field and many example in internet.I try that with "System Workbench"(SW4STM32).The IDE doesn't show anything wrong.adding below to "uart.c" #ifdef __GNUC__ /* With ...
how gpio toogle on STM32 NUCLEO L4R5ZI can be configured?
hello team,I am trying to get started with NUCLEO l4r5zi board. The first program i am doing is to blink a LED on board (PB7) . Problem is the program builds successfully and is loaded on the board . but the LED is not blinking. Moreover the Console ...
Resolved! STM32F0xx : Timer interrupt occasionally processed late or early? Glitch.
I am using a STM32F072 microcontroller with a matrix keypad. The matrix pins are essentially bit banged, using ODR mask commands. When I set up a timer(doesn't matter which one) and I use the timers interrupt (update and a single capture compare) to ...
ST-LINK V2: Command line HALT DOESN'T WORK
Hi, I'm developping a VI in Labview to interface with ST-LINK V2 using "ST-LINK_CLI.exe" and programming ST micro . I'm able with my VI to program micro, write and read byte but when I use the command -halt to halt the core it doesn't work and I rece...
STM32CubeMX v4.26.0 makefile code generation error
Posted on June 17, 2018 at 04:38Hi,I think I encountered with code generation error of STM32CubeMX v4.26.0 in Makefile setting. This is how to regenerate it:1. Create any project2. Generate code with Makefile setting.3. Close CubeMX4. Find the proje...
Reading a 16-bit word via SPI
In order to read a 16-bit word from a current sensor, is it correct to say: HAL_SPI_Receive(&hspi1, &SPIRx[0], 1, 1); //?SPIRx is declared as uint16_t SPIRx[1];I told CubeMx that the data size for SPI1 is 16 bits
ARM Cortex M4 SVC interrupt causes usage fault
I’m trying to write a context switch assembly on STM32F411E but I encounter a usageFault right after I make a second call to the SVC 0 (in my second task) instruction. The funny thing is the first task can make SVC calls just fine but the second task...
