Posted on April 24, 2014 at 22:19This question was asked during a code review. The function that reads a packet from RxFIFO masks the `RxFIFO nonempty' (RXFLVL) interrupt while reading the packet (both in our code and the standard USB OTG device lib...
Posted on April 23, 2018 at 05:58I am using STM32F4 to make a usb msc device using USB-FS and SDIO. EVerything is working great. I am not able to detect the USB transfer complete interrupt. Any clue about it.I am using the most updated version of cu...
Posted on May 24, 2018 at 08:42 I am trying to set up a communication between my STM32F4 - Discovery with Open 407V-D development board and a peripheral using UART3 as a RS-485 bus. I have problem with my communication becouse Rx state of UART...
Posted on January 17, 2018 at 13:09A single STM32H7 SPI（SPI4） DMA master-slave full-duplex communication works very well, but when I add another SPI(SPI5) master-slave communication, the error rate will be high. What is the reason?
Posted on February 11, 2018 at 17:47 Hey everyone, Got a little issue that I'm a little confused on. I want to use a one pulse mode to output a pulse of length dependent on the input signal. So essentially, when the trigger goes off, I wan...

Posted on July 05, 2018 at 10:15Hi, everyone. I'm implementing a shock counter using STM32L476 LPTIM counter & LIS2DH12 click interrupt.I connect LIS2DH12 INT2 pin to LPTIM_IN1 to implement shock counter. ( I expect increment of LPTIM counter when s...
Posted on May 23, 2013 at 11:00Hi!There's question about sleep mode for STM32F103. When I tried to use STOP mode with event wakeup (WFE) and AWU timer, clocking from LSI, and it was needed to control CAN-bus and USART1 at the same time.Could you hel...
