Posted on December 13, 2013 at 08:30I want to connect HID to a stm32 dev board, not using STM32 as a piece of PC's hardware. I've looked them everywhere and wasn't so lucky to find any. Can anyone please help? I repeat, the STM32 will be working at ...
Posted on November 30, 2013 at 13:57Hi In a new layout, my first with STM32F4 ARM, I have done as the refference manual for this family tells me to do when I where to connect the SWD/JTAG . I used PB4 for Reset (<b>nJTRST</b>) . However, I now see t...
Posted on December 14, 2013 at 23:37Hi all, I am designing a board using stm32F4 device and as I am familiar with ISIS from electronic labcenter I want to use it but there is no library for STM32F4 in ISIS. Is there somebody who has such library or ...
Posted on December 14, 2013 at 15:59I have two boards with STM32F0 connected by I2C. First board works like master, second works like slave. I use CPAL library and transmission works fine during normal state. When I make some disturb on the I2C line...
Posted on December 13, 2013 at 10:13 Dear Sir/Madam, I have been trying to understand what I am doing wrong with my serial communication. I am using STM32L Discovery board and have successfully sent and received bytes on my board/PC. ...
Posted on December 12, 2013 at 06:16 I've been coding on the STM32F4 for the past couple years and love the MCU. However, I'm having trouble figuring out how to bring in two external signals and use one as the gate for the other. I'm plan...
Posted on December 13, 2013 at 00:55My application use EXTI1 interrupt, SPI1 interrupt and USART1(RXNE) interrupt. USART1 interrupt has highest priority. USART1_IRQHandler is very short, only storing incomming bytes to the circular buffer. When I di...
Posted on December 13, 2013 at 17:20CAN requires at least two nodes in order to work. I'm trying to determine what the error signature is for a node that is not connected to the network so that the node can go into a timed sleep/retry mode rather t...
Posted on December 12, 2013 at 11:22Hi This is Not a software problem. This is an electrical problem! We are seeing a number of unexpected Flash sector erasures/wipes. Typically, we are powering up/down the system connecting/disconnecting USB or RS...
Posted on December 13, 2013 at 15:43 I've got a problem with using DMA and a Uart. When I reset my uart device, it sends 96 bytes worth of data back to me. I have my DMA and uart configured to put this into a buffer. Problem is that it only puts...
