Board: Nucleo-144Chip: STM32L4R5ZIT6PHey all!I have a curios problem when executing code from SRAM. My firmware lies in flash and occasionally jumps to a externally loaded binary in SRAM. As the cycle count of this binary is quite crucial, I used the...
I supply my STM32G4 with 3.3V. The 3.3V is more like 3.246 Volt. The VREF+ is connected externally to VDDA, which is connected to the 3.246V.My VREFINT_CAL_ADDR is 1662. On the Vref channel of the ADC I measure 1465, so I calculated 3.4034V for VDDA....
Hello,I can't figure out why the STM32H747I-DISCO does not start when I connect an CR2032 Battery to vbat.After turning the external powersupply off and on again, nothing happens and the debugger is disconnected.So I can't easily debug where exactly ...
Hi,I'm currently working on a project with the STM32H750. This project should be able to go to stop mode and wake up with a button press. The normal application/operation (before going to stop mode) is working properly on both revision V and revision...
Hello, Basically i am trying to get data at GPIO with inc with clk. The clk is used as a interrupt. The speed of interrupt is 500KHz.Here i am able to detect each intrrupt but i am missing the data at GPIO and not able to get the same data every time...
We are having problems getting a PWM output from Timer 1(nothing on the PC10 pin.) STM32G070 Low Level drivers Alternate function 2 of PC10 is Timer1 channel 3 Code is based on STM32CubeG0-master\Projects\NUCLEO-G070RB\Examples_LL\TIM\TIM_PWM...
I'm just starting to learn how to program ARM microcontrollers using ST's HAL. So I have this code which generates a 1khz and 20khz signal using a timer in output compare mode. That all works well and I tested it with a scope and it's as expected. Th...
This is the only µC from the family which has not CORDIC according to the page here:https://www.st.com/en/microcontrollers-microprocessors/stm32g4x1.html#productsIs this true? why is this the only from the family to not have cordic function?
Please advise what is the suffix "SP2" in the type 32F45VGT6? Please confirm if this mean device is already programmed?
hi i want to run timer with dma to chang duty cycle for sinusoidal waveform. I already have been tested it on f103c8t but now i want to upload the code on f411ce and it dose not work prperly. dma timer its ok for one channel but when i have run more ...
