Hello! I am working with a STM32U073 on 1.8V and I want to use the USB feature. Indeed, the datasheet tells us that USB needs a separate power supply around 3V (4.1 Power supplies), but every time when I apply this voltage on VDDUSB pin, it goes to t...
Hi, i have configured BKIN pin to detect fault for my overcurrentSo for my motor driver if this pin sense BKIN input. How much time it be will taken by my microcontroller to sense and to act to shutdown my PWM gate signalsIs it hardware glued logic t...
Can Single DMA channel be used for multiple DMA Streams?As per Table 43. DMA1 request mapping in reference manual, Can I use Channel 6 for Stream0 (TIM5_CH3), Stream 3(TIM5_CH4), Stream 4 (TIM5_CH2).I understand that Single stream I cannot use more t...
hello alli am having stability issues with a sample code that uses ethernet with lwip and freertos.practically the operation is unstable, after a few resets it works but then hard faults appear:HardFault_Handler() at stm32h7xx_it.c:88 0x8000f88<signa...
Hello, I try to add MSC feature to my app. MCU is L452.To avoid side effects, I started a brand new app with cubeIDE/Mx.I activated USB_DEVICE feature.I declared the USB_DEVICE as mass storage class.I had a look to the MSC_standalone example from G0 ...
Hi there I am using STM32L051 to talk to a RS485 transceiver and I am having problem with the receive part.System is as follow: laptop->FTDI USB converter-> Renesas transceiver -> STM32I want to update the single byte buffer when a character is detec...
Posted on January 30, 2013 at 12:49Hello all, at the moment I have some issues with the voltages on the STM32F4 Discovery Board. The two diodes D1 and D3 (BAT60JFILM) causes a voltage drop around 0.32V, so that the 5V only delivers 4,68V and not 5V....
I have a general question. I am using STM32F423 and STM32L407 Evaluation boards for practicing. So in both there boards they are using the debugger IC which is STM32F103CBT6.i. Why are they using this IC and what exactly does this IC does in program...
Posted on May 10, 2018 at 14:30I'm developing an HID USB Host application. I have already opened a discussion (https://community.st.com/0D50X00009XkX0ASAV) about HID USB Host and I applied all the suggested patches in forum, but now I have another p...
USB_FlushTxFifoc & USB_FlushRxFifo API flag USB_OTG_GRSTCTL_TXFFLSH & USB_OTG_GRSTCTL_RXFFLSH can not clear when set.
