USB Host mode in STM32F429ZI nucleo board
Hi I'm using STM32F429ZI Nucleo board to work on integrating C270 Logitech camera through USB host. I'm not getting any interrupt in the USB IRQ handler when the device is connected. And it is said that LD8 LED will be ON when the USB is in device or...
Crash when using bootloader to turn off protection
Can anyone confirm whether my understanding of the following behaviour is correct (and whether there's any way round it):When the built in bootloader has been entered by jumping to it from firmware (i.e. the BOOT0 pin is NOT pulled high), and the boo...
Resolved! STM32 MCU's with 10/100 Ethernet MII/RMII module
Does ST have list of STM32 MCU's with 10/100 Ethernet MII/RMII module? Also does ST have an MCU's with 10/100 Ethernet MII/RMII module in 64 pin package.I know for STM32F207xx series 100 pin package.
A problem occurs when STM32 sends multiple CAN messages.
In my STM32 software code three canbus messages sent (extended). When i connect the PCAN Can-USB tranciever i see my messages on the PC clearly. But after a while the state of bus gets "BUSHEAVY" and sending messages stop. Is the problem related with...
Any plans for HUB support in the USB HOST library to be implemented?
Hi,I found two implementation examples of USB HOST HID (for keyboard and for mouse) the examples can be merged, and they seem quite stable.https://os.mbed.com/users/hudakz/code/STM32F407VET6_USBHostKeyboard/https://os.mbed.com/users/hudakz/code/STM32...
Getting Flash writing problems on STM32L4, Memory getting written but memory showing 0xFFFFFFFF
so basically im using stm32l4 as a dual bank, so essentially there are two apps and a bootloader, now im in either app1 or app2 , and i clear the other apps flash addresses, now when i write to that address the data sometimes get written and sometime...
STM32G473CBT freezes jumping to bootloader
I have a custom board using the STM32G473CBT6 MCU. BOOT0 is pulled-down by a 100k resistor and is used as GPIO (output) at runtime. The firmware is generated by CubeMX, with the addition of a C++ file for the 'user' application. The board works fine,...
STM32 Thread Safe Solution for Makefile Projects
I have a Makefile project for an STM32L4 using FreeRTOS that I started with STM32CubeMx. I'm trying to enable one of the Thread-Safe strategies for FreeRTOS. I have tried both strategy #4 and #5, but both of them jump to the error handler on the `S...
Receiving data over STM32F407 or STM32L476's USB OTG using DMA?
Hello!I am working on a project and I need to receive data over USB OTG using DMA, but I could not find any channel link to it. I have configured DMA but I don't know which channel to link with it ( __HAL_LINKDMA(__HANDLE__, __PPP_DMA_FIELD__, __DMA_...
