On what factors the operating frequency of microcontroller (Crystal oscillator) is decided in any application? Generally development board suggest the frequency of 8 MHz or 16 MHz. Please help.
What are the frequency that stm32 microcontroller peripherals work on ?
Resolved! STM32L4 - DAC triggering using timer example
Hi, guys. I'm using the STM32L4 discovery (MB1184C) board to test DAC (Pin PA5).I use Keil uVision 5 to debug the code.I noticed the Timer trigger option and I want to use this.I want to put this MCU to sleep at the main function's while loop.Periodi...
FORTH Compiler for STM32 devices
Posted on October 29, 2015 at 10:36If you want a development system on chip, incremental software updates, test driven interactive developments this is worth a look: Mecrisp Stellaris Forth compiler updated with support for a number of STM32 control...
Implementing phase shifted PWM on STM32F302R8 with asymmetric PWM module.
Hello,Iam trying to implement a phase shifted 4 channel PWM on STM32F302R8 .The PWM signals should look like the first picture. I use CH and CHN complementary PWM generation with deadtime insertion. PWM mode ist asymmetric PWM Mode 1 for both channel...
Hi, I am implementing the bank switching logic for STM32L476 Environment: Eclipse for code development : ST-Link/V2 Debugger for flashing and debugging binaries: Why below code gets stuck at the HAL_FLASH_OB_Launch(); ?
FLASH_OBProgramInitTypeDef OBInit; /* Set BFB2 bit to enable boot from Flash Bank2 */ /* Allow Access to Flash control registers and user Flash */ HAL_FLASH_Unlock(); /* Clear OPTVERR bit set on virgin samples */ __HAL_FLASH_CLEAR_FLAG...
Resolved! ADC1 and 2 timing longer than data sheet values
Hello,I try to setup ADC1 and ADC2, but I don't get the timing values given in reference manual and data sheet. I work with STM32H743 NucleoI have setup RCC to clk ADC with 36 MHz from PLL2P. I checked the frequency at master clock out 2 on PC9. To i...
Resolved! How to get the output of the DAC full zero voltage?
Good day. Faced such a situation. I want to get at the output of the DAC zero level (writing to the register is trivially 0). That's just absolute zero does not work, on the output of the microcontroller there is somewhere around 70mV. The influence ...
Timer6 UIF flag bit is not getting cleared on reading and writing 0 to it in STM32F7 series
I am using Timer6 on STM32F7 series MCU. As soon as I enable the Timer, UIF bit is set in Status Register which is rc_w0, means it gets cleared by reading or writing 0. Then Execution goes to ISR. In ISR when I read the Status register and Try to cl...
STM32F334 HRTIM power consumption
The data sheet says 324.2 µA/MHz. If we take that at face value, this means a whopping 46mA at the maximal 144MHz. Is that really true? It seems a tad disproportionate.I'd be interested in an approximate breakdown of the currents: DLL "base" current ...
