Posted on August 09, 2017 at 20:05I am using stm32f429 discovery board. When I use pwm on any timer, I am not getting correct outputs, that is my duty cycle is not matching the values in the ccr and arr registers.void enable_gpio1(){ RCC ->AHB1ENR |...
Posted on August 07, 2017 at 20:59I am testing out the USB HID (otg fs) feature of my board with stm32f407vet6 mcu. I used stm32cubemx to configure it and i didn't add anything to the while loop in main c, just seeing if the device can be detected o...
Posted on August 08, 2017 at 19:47In my code for pwm on timer 2 in stm32F429, I have to use multiple channels (2 at a time). However only my channel 1 pin is giving pwm output. Please advise me what to dovoid enable_gpio1()//setting pin 5 of port a ...
Posted on August 09, 2017 at 19:41Hi First I will give info about my project.I am generating PWM using timer, then SPI using Full Duplex slave mode and a GPIO pin. PWM is connected to SPI sclk and GPIO is connected to NSS.I am transferring data from...
Posted on October 19, 2012 at 10:39Hi, How can I setting rtc to put alarm every 1 day , for all day? Is possible (I need to wake up stm32f0 every 16:00 pm all day , execute routine and do sleep and wait the next day)
Posted on August 09, 2017 at 09:34Hello All ; I use STM32f407 ; I connect Vref to VDDA to VDD ; but VDD is connected to super cap that can be change from 2,9V to 3,5 volt ; so my ADC reading would be change ; Does STM32F407 has internal Refence ? I ...
Posted on July 21, 2017 at 08:51Hi,Apologies ahead of time if my terminology isn't spot on, pretty new to this.What I'm trying to do is accurately time LOW to HIGH events on 8 separate pins relative to each other. I've calculated that I need 32 bit ...
Posted on August 04, 2017 at 15:30Hello , defuse demo is compatible with stm32f7xx ?
Posted on August 07, 2017 at 12:31 Hello, I have the following problem: I have a I2C communication routine that takes about 2ms to be executed. After I do the first read/write operation on a SPI peripheral, the same routine takes250ms the f...
Posted on August 08, 2017 at 14:52I'm using STM32F103CB to convert the analog outputs from three polar hall sensors arranged circularly, a magnetic actuator rotates in the center, but I get the voltage value with strange breakpoints, and these happe...
