I'm new to embedded programming and don't know how to deal with registers therefore I'm looking for a library that is readily available.Thank you.
Please help me understand the relationship / layering between STM32 HAL drivers and Keil drivers.Is it fair to say that STM32 HAL drivers are layered above CMSIS-CORE?Is it fair to say that Keil drivers are CMSIS compliant (CMSIS-Drivers), also layer...
I have an SM32H723 NUCLEO-144 board. I successfully implemented COMP1. It works, but I have some bouncing at the rising and falling edges (100Hz signal). I found a COMP_OutputBlanking example for NUCLEO-H7A3ZI-Q (No blanking example for NUCLEO-H723ZG...
My code is based on LL SPI-DMA example.The original code does not have chip select, so I use one GPIO pin as CS pin. /* Start SPI Tx/Rx */ ADC_CS_Low(); /* Enable DMA Channels to start Tx/Rx */ LL_DMA_EnableStream(DMA2, LL_DMA_STREAM_2); L...
STM32 TIMER PWM (10KHz) very duty cycle for very output voltage.now i want (0 - 10V DC) analogue output voltage is very by changing duty cycle of TIMER PWM (0 - 100 % duty).what is the circuit diagram for PWM IP to ANALOGUE OP?so for example: 10V DC ...
Posted on November 29, 2014 at 13:07 Hi, I have strange problem with making SPI DMA transfers working. It works only one time, the second dma transfer is not performed. I use similar coding for USART and it works perfect, but SPI doe...
Im using a STM32L412, I've made the config in STMcube but when I run the program (no main code, just the setup routine) it never reaches the main loop. By placing breakpoints I have deduced that SystemClock_Config(); runs over and over again. It see...
Hello All,I am working with an STM32H743 and am having issues reliably erasing flash (unreliable in that it fails ~95% of the time). The code which erases flash runs from RAM (functions are allocated in RAM). I disable many of the interrupts before e...
Hello!I own an STM32F769I-DISCO board and I have just read that it is already possible to use a serial Wi-Fi module (called ESP8266-01). However, I have been wondering for some days whether it is also possible to use a 4G communication module with th...
I measure the execution time of a function by putting the toggle of a digital output and the function call into a cycle and measuring the period of the square wave at the digital output with an oscilloscope. The execution time is half a period. To te...
