I want to program a double word (a calibration value) at the top of internal flash (STM32G03x) without erasing the entire page first. I understand that only 1's can be set to 0, not vice versa. It may be assumed that the address in question already c...
Hi,This was part of another (unrelated) thread which did not get timely attention.Prototype sketch:Cube programmer screenshot:CubeMX ioc file attached.The PCB manufacturer allows window of one week to submit a modified prototype within the same quota...
Hello Community,i have the strange behavior that the Clockswitch to HSE does not work in STM32L051. __HAL_RCC_SYSCLK_CONFIG(RCC_ClkInitStruct->SYSCLKSource); /* Get Start Tick */ tickstart = HAL_GetTick(); if(RCC_ClkInitStruct->SYS...
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.
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...
