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...
UART DMA receive unknown length of data (maximum data length 64 bytes) but in every message terminate with 3.5 char times silent interval ( MODBUS RTU FRAMING) so to detect silent interval i'm using IDLE interrupt occur before new message start.When ...
Hi,I try to work with the JSN-SR04T distance sensor. The working principle is very simple :put the trigger pin to high for 10 uscount the elapsed time in us on the echo pin between the rising and falling eventdistance is proportional to the elapsed t...

HelloHow can I download User Manuals of STM32F7508-DK?No User Manuals of STM32F7508-DK in st.com. )I cannot download even via STM32CubeMX.(file name : UM2470 Discovery kit for STM32F7 Series with STM32F750N8 MCU )Thank you.
Hello, I am using NUCLEO-F429ZI. I add one battery on my board and work on RTC. RTC is working, however, all time(null), clock() and so on don't work properly as soon as I remove semi hosting. After I dig the information, I know time(NULL), clock()...
trying to read from external SDRAM like device, 16 bit data, 10bit address, Mode A (not extended timing) a page of data in a loop of one second.The first read page succeeds and all data is received correctly.After that i can see that further reads (f...
Hi, This is sureshkumar, I bought one STM32 popular udemy course, on that course have one video that trainer shows some registers to set the pin directions. but my data sheet is showing different name of the register. on that video showing MODE regis...
Hi,I'm using STM32F207 and I'm trying to make three different ADC measurements on three difeerent ADC.My purpose is to make 100.000 measurements on each of these signals at the highest speed possible.With only one signal (so using only one ADC) I can...
In many of the STM32 processors having LPTIMx timers the CNT register is read only and there is no explicit reset which will clear the CNT register. The following is an undocumented hack which will accomplish the equivalent of a reset of the CNT reg...
Hi!I would like to know if there is any chance on waking up a STM32L0 (from stop mode) with an ADC in windows whatchdog mode. Probably the ADC won't operate in that mode. because of the clock. Or the ISR source won't wake the CPU.
