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. ...
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 ...
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 ...
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 ...
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...
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...
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
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...
I have an LCD is on an 8080 16bit FMC interface with A0 register select.I can read the status correctly here:#define LCD1_DEVICE_ADDR (uint32_t)0x60000000 #define LCD1_DEVICE_DATA (uint32_t)0x60000001 uint16_t *pLcdRStatusWAddress = LCD1_DEVICE_...
