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...
Hey guys, I am trying to get I2C working with DMA or without, but I am having similar issues with both. The I2C sends out the data correctly the first time via DMA and the DMA_TC interrupt is called, however it gets never called again. I can also see...
Hello,I was following the step by step guide by st for an easy led blink program. And after configurating the pins in the GPIO_Init function the LEDs are not turning on. Is there something wrong in my code? Did I miss part of the pin configuration? A...
In looking at various LPTIM training documentation it's indicated very clearly that the LPTIMERs have a CNT reset as a function of setting bit 4 of the CR register. As this is an important capability, there seems to be a number of reference document...
I'm using a timer as a 1ms timebase, which is configured right after hitting main, so very early. I use this timebase to implement timeout functionality in my drivers as I prefer to not just use while loops when waiting for something to complete.What...
Hi,What is the jitter value in nS when the ADC is configured for Asynchronous clock mode? consider CPU clock = 170MHZ, adc_hclk = 170MHZ, adc_ker_ck = 170/6 MHZ = 56.67MHZ and ADC clock = 56.67MHZ (PRESC = 0)ST inform in the manual that the jitter i...
I'm using triple interleaved ADCs to fill a buffer (6000*16bits) in circular mode via DMA,and I needed to know when I wanted to read the whole buffer via another DMA request and write it to a second buffer to be processed offline later would I need t...
I'm trying to port some code from a Discovery F7 Board to the dual-core H745 Nucleo board and I'm going to make use of the following peripherals:ADC, DMA, SDMMC, Ethernet and UART. I have this all working on the Discovery board but I'm having trouble...
I'm using STM32F031K6Tx in my design. I have given provision for both UART (PA9/PA10) & SWD (SWDIO/SWCLK) for programming MCU using test fixture in the factory. Either one will be used1) Is BOOT0 (0 = Main Flash Memory; 1 = System Memory) needs to be...
