I have a STM32G071 where, among other stuff, an UART interface an a GPIO input are configured. UART is mapped to PA9 - PA12 (Tx, Rx, CTS, RTS). PA8 is configured as GPIO input mode (no pull-up, pull-down). On the net connected to PA8 is a hall sensor...
1.Assembly language2.C language without HAL3.C language with HALAnd why you choose that method ?
The documentation for the DAC says "A DMA request can be generated when an external trigger (but not a software trigger) occurs if DMA requests are enabled"But I want to configure the DAC to have no trigger, and instead use TIM12_TRGO to drive the DA...
I am working on STM32H743 MCU. I generated the initialization code used stm32cubemx v5.3.0 and embedded firmware package for STM32H7 V1.5.0. I am using keil uvision v5.28.0.0.I initialized uart1 in interrupt mode. I am receiving data in buffer until ...
I am using the Nucleo-F767ZI board. I have the normally open of the switch wired to 5V.Common is to pin A0 and to R10K then pulled down to GND.When the button is pressed the pin A0 will go from 0V to ~5V.Want to blink LED1 at say 1Hz, then when butto...
Hello,I am working on Nucleoh745ziq .Its have two cores cortex-m7 and cortex-M4, how making the communication between two cores. They give the example code for that but they doesnot give the proper information, which parameter we can configure in c...
On an 'F4, I was working on a lengthy piece of floating-point calculation, and had to benchmark it, so I thought I'd share some of the results. Basically, this is a linear calculation with moderate amount of constants and quite liberal amount of sinf...
Hi All,I have a situation where I would like to allow STM32H7 based embedded web server users to update the password which is originally hardcoded in the code using const keyword. Which effectively means password is placed in internal flash memory o...
Hi Experts, I have a project like below. I am trying to send the data using SPI but the LEDS are not glowing in sending pattern. I am new to STM32. Could anyone please let me know if SPI can be used in this scenario OR not. STM3...
i want to build continuous potentiometer with dma which is sensing wind direction . I have to use modbus because send data on an another STM32F070F6P6 microcontroller, but in the reference manual pdf(page 22) it says we can't work modbus communicati...
