Posted on May 19, 2014 at 21:41I'm wanting to update a product that has a SPI device on the same channel as the UART. Currently the SPI device uses DMA - it sends 1 byte and receives a packet of info. On the UART we only send data.I would like to ...
Posted on May 19, 2014 at 22:52Hi I made VCP from ST sample on ST32F405 (STM32_USB-Host-Device_Lib_V2.1.0 & DriverVer=04/25/2010,1.3.1) When I send data from CPU to PC less than 64 byte, all work fine. I have 2 problems: 1) When I try send data from...

Posted on May 15, 2014 at 16:58Hi, I am using USB HS port in the FS mode in my vcp project. When I used it to communicate to PC, it works ok if I re-plug in the device to PC. The problem is if I just reset the MCU from IDE debug, the device cannot ...
Posted on May 19, 2014 at 03:47Hi AllSTM32F2xx:I assume this is not possible but....Can a DMA transaction have the read strobe only without the write strobe (ie half the transaction)?The reason is due to our project having an FPGA being mapped onto ...

Posted on May 19, 2014 at 16:33I am trying to use the ST Flash loader software for download STM32F401 and there is a problem when the software tries to read the address 0x1FFF7A22 (contained flash size) and 0x1FFF7A10 (unique device ID). It seems th...
Posted on September 23, 2012 at 22:17I am having a strange issue. I am using FatFS and I have setup the SPI1 withCS - PB14CK - PA5MISO - PA6MOSI - PA7When I just use the SD card interface, everything works well. I am getting the proper SPI signals a...
Posted on May 14, 2014 at 11:53I have a question about connecting specially device to a FSMC interface on STM32F207IGT6. There is some points describing this case it bellow.- MCU: STM32F207IGT6 - DEVICE: ...
Posted on May 14, 2014 at 11:54Hello, I've problem with a clock setting for a MCU. There is some points, which describe it. General: MCU: STM32F207IGT6 Clock: HSE 8Mhz -> PLL 96Mhz Using module: ETH MAC - MII 4-bit mode - 25MHz neededFSMC - synchro ...
