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...
I am using ADC DMA to read 100 sample from 1 cycle input sine wave whose frequency is 1KHz . When we using ADC to read DMA, the DMA reads ADC continuously until buffer is full. I want the DMA to read and store ADC data in buffer one at a time when it...
Working with a L4R5. I have chained TIM1 & TIM3 to create a 32 bit 1mS counter.Is it possible to reset both counters on an arbitrary 32 bit value?I would like to limit the count to 0x240c_8400; msec in one week.I understand how to reset a timer base...
There is a discrepancy between rev 8 of the datasheet and rev 7 of the reference manual regarding the PLL VCO output range parameter when the PLL is setup in wide VCO frequency mode.In section 7.3.10 of the datasheet, the VCO output range is between ...
STM32g491KE MCU does not reset in debug mode, debug session hung up right after I press Restart button.CubeIDE 1.6.0 generated projectSegger J-Trace Pro using SWD interface
I use the NUCLEO-L4R5ZI Evaluation Board.I use STM32CubeIDE with HAL and gcc.When i activate an Timer Output Channel (I have tried it with Output Compare, PWM, Forced Output) i get a Signal:0 in the gdb after the Timer init (e.g. after call of MX_TIM...
Issue traced to offset value for EXTI.EMR1 register in SVD file should read 0x84, not 0x80 which is EXTI.IMR1
Is there a difference in the port pin setup, between I2C and SMBUS-two-wire mode?Say the STM32F469NIHx, if I set the mode to I@C, but the MCU drives a SMBUS device, is there any potential problem?Any help appreciated
I want to design a GPS car tracker that alarms when the speed reaches a certain value and I want to first test the code with the USB to TTL module which is connected to my stm32, and simulate sim808 answers. when I send the GPS information only the f...
Hello,Has anyone ever used the emulated usart provided by ST (AN4457) based on timer and DMA?I need it for transmit, not for reception.In my test, most of the time TX characters are corrupted, sometimes it works.I checked with scope and it appears th...
Looking at the pinouts for the 20-pin JTAG connector on the CBA being programmed, I see:1 - 3.3V2 - JTMS3 - GND4 - JTCK5 - GND6 - JTDO7 - n/c8 - JTDI9 - GND10 - /JTRST11-20 - Odd pins are GND, Even pins are n/cLooking at the STDC14 connector pinout f...
