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...
Posted on May 13, 2018 at 10:40I recently got a DISCO-F413ZH + X-NUCLEO-IKS01A2 Motion MEMS and Environmental Sensor, and going through the example on MBED5 here: https://community.st.com/external-link.jspa?url=https%3A%2F%2Fos.mbed.com%2Fteams%2FS...
Posted on March 16, 2018 at 12:11HiI want to use SIMCOM7100E GSM module with STM32 board with MQTT protocol stack embedded on it.Is there any STM32 development board or any STM Development board which supports MQTT protocol stack with simcom7100E GS...
Posted on May 11, 2018 at 22:55Hello Guys, I am using STM32 L476RG microcontroller. I am trying to program it with ST Link V2 and ST link utility. The utility recognizes my microcontroller however when I try to drag and drop the code, I get a fail.T...
Posted on May 18, 2017 at 22:46Hi.I'm trying to use TIM1's channel 1 as a spindle RPM input capture. ( device is STM32F103C8 )Knowing that the spindle has a single pulse per revolution and is rated from 0 to 30K rpm, the frequency domain is 0 to 500...
Posted on May 11, 2018 at 20:57I'm using TIM2 as a PWM. I have an (periodic) external signal that should reset the TIM2 counter to zero, so that the PWM is synchronized to the external signal. In a previous naive setup, I used the external signal to...
