Hi,If I am starting with 120 MHz system clock and want the master timer to generate a 60 MHz PWM waveform and I want the second timer to generate an in-phase 8 MHz PWM waveform I must clock the second timer with 120 MHz (as 60 MHz isn't divisible by ...
Hi, I've 2 Nucleo boards (Edit: Nucleo -G431RB )to communicate between FDCAN. I create a project using CUBEMX. Default FDCAN RX/TX is PA11/PA12. and I have no problem getting it work. All worked fine. But I also need USB so I moved FDCAN Pins to PB9/...
Hi, I need to count the number of pulses from a device which is connected to STM32 IC. For counting pulses i have activated the interrupt using Timer 2 and i have used channel 1 (PA0).The parameter setting for enabling and using Timer2 in CUBEMX is g...
If the bit in Pending Register of STM32 is not cleared.Will interrupts trigger all the time?Will the Interrupt service function always run?
on the SMT32L475 Discovery kit IoT, I would like to implement the following commands from Arduino:Serial1.begin(BPS, SERIAL_7N2); Serial1.print(msg) while (Serial1.available()) { t = Serial1.read(); wmsg[ct] = t; ct++; *bufflen = ...
Hi,My application is to copy the content (32-bit Data) in the Memory to PORT ODR each time it detects a Falling Edge. I use DMA1 from TIMER CCP pin. The problem I have is, DMA1 will stop as soon as it complete the transfer and require to re-enabling ...
I'm curious to Know before purchasing this Board a few things,Our need is , the Board shall be reliable to adapt the Other Quectel Modules as well like for Indian Bands i.e EC25-E modems from Quectel.The issue is in India, LTE-M is not operational, s...
I am using STM32F407 Discovery Board and I'm generating my project using MX Cube I'm doing testing on I2C sensor that is MLX 640 which is used for taking thermal image , so basically we are are reading frames of thermal image via I2C on every 1 sec...
Hi, i'm trying to use the LSE clock with the RTC but it doesn't start until i make a state reset or run the code under debug mode.I have read all other posts of LSE problems in the forum and found a lot of info, almost everything related with hardwar...
I do some serial interface clock with timers chain on stm32f407.Thats work, but generate little bit lower count of impulses. where is my trouble? len is about 16 384, overall pulse count len*16.I miss about 200*16=3200 pulses.Thank You!TIM2->PSC=0; ...
