STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
Hello, I'm doing a project for speech recognition. I have a buffer of 512 values and I want to test every state of the ASR I'm implementing. I am using Keil ARM as IDE and I have tried to use the logic analyzer to plot my buffer but I can only plot ...
