Posted on January 21, 2015 at 10:34HiI'm a relative newbie in using ST or ARM devices, and I'm attempting to get a USB CDC device working using the VirtualCom example code, using an STM32L152 in a custom pcb.I'm using the Kickstart edition of IAR em...
Posted on November 27, 2014 at 15:12Hello all,I have a quick question regarding the USB FS speed on STm32L151.I managed to modify the sample code for USB VCP and get the USB running. I'm streaming my data to the PC succesfully.The question is follow...
Posted on January 26, 2015 at 16:01Hello there, I am new to STM32 but I have some expirience with AVR8 and 32. I am trying to make a simple demo program using stm32f4discovery board that would allow me to send and receive data on CAN1 channel. For t...
Posted on October 12, 2014 at 18:31 Hello everyone, I am trying to port my software to HAL drivers and came across a problem with use of circular buffer. I use it on the RX of UART to continuously receive data. It works as it should on th...
Posted on January 20, 2015 at 14:41I am getting a very annoying problem where my SD cards are becoming corrupted after recording data through a custom PCB. I'm using the SDIO driver (fixed for 4GB), that clive has made available in the forum, for in...
Posted on January 25, 2015 at 16:42 I have 5 stm32 boards, 3 with F103RBT6 , 2 with F103C8T6. I build an USB HID firmware by using USB FS Device Library 4.0, the code is just modified from the custom HID demo in the ST USB device library...
Posted on January 25, 2015 at 01:02Hello.When do you plan to support C++ for HAL library STM32L1xx ? #hal #stm32l1xx #c++
Posted on January 20, 2015 at 06:45I will make minimal uart reciver with HAL, by STM Cybe, but it don't work.Test code is atached.I use stm32f4-discovery, there i will connect PC6 to PC7 and run attached code. ANd nothing happens - no any will be re...
Posted on January 26, 2015 at 09:16Hi folks, I searched for an implementation of USB networking for STM32(F4) but did not found anything. Did someone already implement CDC-EEM or CDC-RNDIS, and willing to share the code ? Cheers. #cdc-usb-network
