Posted on July 07, 2015 at 20:47Hi all, I am using STM32F407 chip with GCC toolchain. I have a trouble with my code. I wrote a function that needs an exclusive access to variables (I want to have ability to call this function from interrupts as we...
Posted on July 08, 2015 at 09:25I have a STM32L152C Discovery board. I want to use a 1GB FAT SD Card with STM32Cube and EWARM ide, but there is an error. pins: STM --- SD Module PA5 SCK PA4 CS MISO MISO MOSI MOS...
Posted on July 08, 2015 at 08:14I'm using stm32f429. I have configured my system core clock to 160Mhz and I use the APB2 clock divider as 4, which gives me 40Mhz to my SPI4 peripheral , I want to use my SPI peripheral at 30Mhz, since the SPI core cl...

Posted on July 06, 2015 at 14:20 hi everybody! I'm developing on st32f0 a device with two analogics sensors. After the initialization, I can read properly one value but the other is always at it s maximum value (4095 for 12 bits of data). ...
Posted on July 07, 2015 at 20:13I've seen at least two other threads with an inverted DAC concern being present, wondering if anyone has more information o the issue? I have 3 identical boards in house populated with the F4, one of which has an inve...
Posted on July 07, 2015 at 17:00 I used STM32 cube for the PLL configuration // Enable HSE Oscillator and activate PLL with HSE as source RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_...
Posted on July 07, 2015 at 18:18I've been testing a STM32F4 Discovery since I'm new to ST Microcontrollers and I wanted to use one timer to measure 4 different channel frequencies, as I want to measure more signals than there are timers. I do not ca...
Posted on July 07, 2015 at 07:04Hello,I would like to generate number of pulses on timer3. I am using two channels PB6&PB7which runs at different period, but on same timer. For that reason I am using OC1&OC2 and I am counting number of pulses at ea...
Posted on July 07, 2015 at 11:49Hi guys, I have code that has been working great for a couple of months now on an STM32F415VG, but I added some libaries/code yesterday which took it beyond the flash sectors that I wanted it to sit in (it's a custom ...
