Posted on May 21, 2014 at 13:48HelloWe have made a custom board which uses a STM32F429II. On that board we also have a SDRAM memory chip of 512Kbit that is connected to the STM32 with the FMC peripheral.We confirmed that the memory chip is working c...
Posted on April 17, 2013 at 00:21 I'm using the STM32F4x7 + LwIP example code, modified to work with RMII and a LAN8720 PHY. I can send and receive Ethernet data - great! Unfortunately whenever I send a UDP packet, it has 50 bytes more pa...
Posted on May 20, 2014 at 13:39we've made an oscilloscope that displays data on PC screen with a software,which is creted on Qt Creator. The MCU software works well on STM32F4 Discovery board,which has STM32F407VG; but when we program STM32F405RG,pr...
Posted on April 23, 2014 at 19:53 My goal is to jump from bank 1 to bank 2 at the start of main. I'm trying to follow the example in this forum post: /public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=https%3a//my.st.com/...
Posted on May 20, 2014 at 13:41Hello all,I am interested in PMatrix area detection (PMAD) of STM32TS60.I would like to know how PMAD works to obtain the touched areas. The exact way how it works is not explained in the reference manual.Is the under...
Posted on May 19, 2014 at 15:18Hello all, I'm searching about example for USB dialog with USB OTG connector. I don't understand what are difference between HID, CDC & MSC ? My project is dialog with a usb device which only response to me. Please hav...
Posted on May 27, 2013 at 13:55Hi, I would like to connect an STM32 board into a WiFi network, to exchange a LOW amount of data from time to time (for control / data sampling, only some 100 Bytes per minute or so). Concerning hardware requirements, ...
Posted on April 15, 2014 at 17:05According to the usermanual (UM) and datasheet, the STM32F4 has 6 in and 6 out endpoints in Highspeed (ULPI) Mode. When reading the UM and having a closer look at the register tables I found out that the registers D...
Posted on May 13, 2014 at 11:31Hi All, I'm interested in the feature detailed in the v3.4 changelist which allows probe selection if multiple probes are connected, but the only version for download appears to be 3.3. Any clues as to the location of ...
Posted on May 09, 2014 at 03:22Hi, I have a board with an STM32F429 and an 8 MHz crystal on the HSE pins. I'm using Atollic TrueSTUDIO to upload and debug code. I can upload code without a problem, but as soon as the the debugger starts, the crystal...
