I have a CAN-BUS line communicating at 50kb/s speed. There are only 2 products communicating with each other on the CAN-BUS line. One of these products has the STM32L496RGT MCU (the clock speed of the CAN module (APB1) is 80Mhz.) and the other one ha...
Hello,I would need to know for future productions, what is the approximate end of life date of the following references:STM32L451CEU6Thank you
DearI have configured TIM1 Channel1 as PWM and I would like to use the NPWM feature too.Therefore I have configuted the channel as PWM NPWM channel and set the according GPIOs.I must have made a mistake in the MXCube configuration.The PWM output perf...
Evaluating STM32G0, I noticed in product brochure en.flstm32g0.pdf :Embedded Software The STM32CubeG0 package includes the STM32Cube HAL and lowlayer (LL) APIs peripheral drivers, plus a consistent set of middleware components (RTOS, USB, USB Power D...
Greetings:I'm using Circular DMA on an STM32F303 for double buffered acquisition of multiple signals: ADC, Quadrature counter (TIM2), etc. I was depending on the Half Transfer (HT) to tell me the 1st half of the buffer was filled, and the Transfer Co...
I'm using a STM32F070CBT and putting it to stop mode with low power regulator on and waking it up with GPIO events.In our project, we're using every single pin from the MCU, most of those are timers and GPIOs, NFC tag reader, etcAfter waking it up, w...
Hey,If a power off occurs, I would like that the RTC function will keep alive, until Power on.As I understand, i should connect a coin battery 3.0 to VBAT pin.My questions are:when power is on, does the VBAT PIN supplies from VDD (P3V3) or from the V...
Hello all,I am unable to save time or restore proper time after I remove Vdd from my MCU when connected to a external 3V li ion battery (DL2032). After every power cycle my time gets reset to its initial default value.When I supply 3V from a regulate...
Hi,I'm trying to port my project over to Keil uVision, but I'm having hard time flashing the device. It seems that my target values are incorrect.I'm looking for help to get me at least some basic settings done in the scatter file and what settings t...
Hi,I am trying to recieve unknown number of bytes using DMA in circular mode. My buffer size is 2048.After reaching this size, CNDTR becomes 0 and never reinitialized again. It stays 0 always. The bytes coming after are getting lost.Has anyone faced ...
