Posted on May 13, 2018 at 21:19Hi, I am looking for bsp in keil for nucleo144 board but i am not able to find it in the latest version of the keil. Where can i find the bsp for the same? What is the procedure?
Posted on May 13, 2018 at 22:00hello everyone ,please I try to get a voltage in the pin PA0 of a stm32F3 DISCOVERY and convert it with the adc of this pin and display it on system workbench, but I need a code on the software Basic workbench system t...
Posted on May 09, 2018 at 12:54Hi.I want to do do ADC conversions on all 3 ADCs simultaneous: they should be done in the same time. How should I achieve that?1. With DMA? I can do multichannel conversions, but they are not simultaneous. When I start...
Posted on May 11, 2018 at 15:32I'm using FatFs with SDMMC1 on a Nucleo STM32F722ZE with CubeMX 4.25.My project uses FatFs to manipulate a MicroSD card, but I noticed that many operations just fail randomly, usually with FR_DISK_ERR. For example, in...
Posted on November 10, 2017 at 08:25Hello,I'm trying to measure the frequency of a PWM signal ( 600 Hz) with the Input Capture functionality with an STM32F103.I do these steps: Configure the Tim4 as Input Capture. Timer Clock 64 MHz;Prescaler =...
Posted on May 13, 2018 at 11:22Hi,I'm working on a fairly complex code written by other employees at our company where interrupts are globally disabled and enabled in multiple places using:__enable_irq();and__disable_irq();Sometimes it is not clear ...
Posted on May 11, 2018 at 13:05I'm using STM32F030R8 @ 40MHz and TIM6. I want to wait for some time without blocking main function, so i used TIM6 - code below:TIM6->CR1 |= TIM_CR1_ARPE | TIM_CR1_OPM;//auto-reload, one-pulse TIM6->PSC = 4000-1;//100...
Posted on May 06, 2018 at 14:03Hello I am prototyping with an STM32F3xxxx and trying to figure out how to configure a timer/s to operate a half bridge smps.The normal situation would be that there is a divide by two circuit in the block labelled 'ou...
