Posted on February 01, 2018 at 21:39Hello!The HAL CAN driver for the STM32F4 got reworked lately (december 2017). I try to port my code from the old to the new drivers (compatibility break). There is a brief driver description in the update history ...
I have stm32f4 discovery board(STM32F407VGT06) running at 168Mhz. requirement 1) i have to run a motor (AC synchronous servo - yaskawa ) by pulse and direction.for which i can use a timer in PWM mode with 50% duty cycle. relat...
Good day.The reference manual RM0033 for the microcontroller (in the Boot configuration section) states that "When the device boots from SRAM, in the application initialization code, you have torelocate the vector table in SRAM using the NVIC excepti...
Hi, I am synchronizing two timers, actually already succeed but I was stuck two days because the trigger output event TRGO of TIM1 was connected to OC4REF (and CCR4 was accordingly set).With this configuration I didn't receive a pulse in the slave tr...
I read TS_CAL1 and TS_CAL2 values from stm32f303vc and saw that TS_CAL2 is lower then TS_CAL1. Is it correct? I think this is mistake. I check the memory with Visual Studio in debug mode and saw the same values. Why is it so?Thank u in advance!
I've a problem with UART on Bluepill (STM32F103C8T6). Let's say that I need to send some string via UART periodically using Std Peripheral Library . Below I post simple code which 'propably' should work. What I know for sure is that devices (bluepill...
HelloI'm very new to the STM world (just came from arduino) and I'm learning about timers and PWM. I have some questions about some settings that I cannot seem to find any answers. What is the difference between PWM mode 1 and 2And what is the differ...
Is there a fast way to use MCO, mux it to an internal clock souce and use a timer to realize some kind of on/off modulation of the MCO pin?I muxed it to an internal source and tried switching the GPIO between input and output. This works fine but nee...
Hi. I am trying to read 4 ADC Channels sequentially in interrupt mode: ADC2_IN7, ADC2_IN14, ADC2_IN15 and ADC2_IN8. However it only reads the last rank channel every time. Please help me understand what I'm doing wrong.Compiler: IAR Workbenc...
Hello,I am trying to implement I2S protocol for my project with STM32L433RBT6. I should play short (up to 5 seconds) .wav stereo audio samples that are with 44.1 kHz sampling rate and 16 bit audio sample. The I2S line goes into the CS4344 DAC. Thus, ...
