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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on July 27, 2017 at 12:14Perhaps the title is wrong, but my code behaves like this: I have configured 4 channels to be converted in the ADC; I have put a variable which increments inside ADC irq EOC (EOC_Counter) and another which increments ...
Posted on August 01, 2017 at 16:53Hello,Included attachement consists screen of internal reference parameters presented in datasheet.I think there is mistake because Vdd=31.8V seems not correct.I try to calculate how accurately can determine Vdda vo...
Posted on July 31, 2017 at 18:48Hi, engineers. I am currently working on project, containing SD card. My HW is custom chinese board with STM23f407VET6 mounted and microSD slot connected to SDIO (proper pullup resistors seem to be in place). I made s...

Posted on July 26, 2017 at 09:58Hi Communities, can any body please explain me, how works exactly the function HAL_SAI_Transmit_DMA(). I am using STM32F746VGTX.This is one example:uint8_t TestArray[4] = {0x00,0xff,0x00,0x00};HAL_SAI_Transmit_DMA(hsa...

Posted on July 26, 2017 at 12:15Hi,When i checked on DSO (scope) i found that after chip select SPI_NSS latch to ground.there in clock signals on clk pin.there is no data on SI and SO pin.Why there no data on SPI's Pin?Why SPI_NSS latch to ground?...
Posted on July 27, 2017 at 07:33i have purchased a stm3210c Eval board , want to establish ethernet connection but unable to do itpls tell me the solution , and suggest how to transmit data from microcontroller to PC via ethernet
Posted on August 01, 2017 at 04:08First, I introduce the background simply. I have program the STM32F072RB for somedays. I do this project start with STM32CubeMX. It�s going well until now. I have using the 2 DMA for SPI transmit before. And I want ...
Posted on July 10, 2017 at 07:49HelloI want to generate a 50Hz stable sine wave which I will amplify in order to obtain AC and DC voltage and current.The strategy is to generate the sine wave using DAC or PWM. I used one STM32 MCU with two DAC outpu...
