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...
Posted on May 19, 2014 at 15:14Hi everybody, I have an unstable behavior on an ADC interrupt.My user code is very simple, I initialize my different peripherals (timer, ADC, GPIO) then I just a have an infinite loop.My Callback for my ADC interrupt ...
Posted on May 21, 2014 at 05:21 Hi I try to measure the frequency and duty cycle from timer 2 channel 2 with input from another timer output. The chip is STM32F103 and the TIMxCLK is set 32 Mhz. The interrupt handler is periodically trigg...
Posted on May 21, 2014 at 03:52Browsing through the STM32 F405 datasheet, I'm noticing serial ports with functions listed multiple times even on the same chip. At first I assumed (for example, USART1 TX) would be listed multiple times, but on any gi...
Posted on May 18, 2014 at 22:43Hi,I used the stm32f3 discovery board to test some code and it works fine but when I run the same code on a custom breakout I made around the stm32f303cc it runs for a while and then stops.The time it takes for the boa...
Posted on May 20, 2014 at 23:54Hi, I'm trying to use the 4K SRAM from STM32F427 with FreeRTOS 7.4.2. The VBat pin is correctly powered to a battery... The RTC works great. I can access to SRAM memory and use it. At each reboot I can grab the data st...
Posted on May 17, 2014 at 23:48I trying to send continuous serial data at 115200 baud using USART2 which is connected to the ST-LINK portion of the NUCLEO board. ST-LINK implements a VCP which I'm accessing via a terminal on my PC. If I space the ...
Posted on May 20, 2014 at 16:46Hello,I am trying to get the reference voltage value with ADC (Channel 18).On the VCT6 datasheet, it is said that reference calibration values (for VREF) are stored in memory at the address 0x1FFFF7BA. (Value for VREF ...
