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...
Hello... Tell me, is it possible that microcontrollers with sram 10 megabytes and more will appear soon?
Issue detailsWe have observed a situation where a full duplex HAL SPI transfer in IT mode would hang in permanent BUSY state after many transfers in a system with relatively long ISRs at higher priorities than the SPI.Debugging showed that the lockup...
We want to use 10 PWM from HRTIM, 2 PWM from TIM1. However, we don't know how to synchronize these two timers. We can synchronize all PWM signals of HRTIM but could not do it with TIM1. We need one master clock and others (12 channels) as slaves. Ple...
