Posted on November 06, 2014 at 22:23I have implemented a USB virtual serial port (CDC) device using the USB HS interface on an STM32F429 processor on an STM32F429I-DISCO evaluation board. The virtual serial port acts as a communication link between ...
Posted on January 08, 2014 at 16:43Hi All,I am using STM32F4Discovery board to log data from six analog channels at 50 KHz on micro SD card. Thanks to this forum for the help through various posts, particularly from Clive1. ADC operates in triple AD...
Posted on November 06, 2014 at 17:30Our design is operating properly on 3.1V PSU. When we try to start it with 2.9V PSU, it does not start.If we boot at 3.1 V and then reduce the voltage to 2.9V, it stops.The Brownout Reset (BOR) is set to 'disabled...
Posted on November 06, 2014 at 15:07Hello, I am designing a PCB for STM32F301K8U6 (UFQFPN32 package) I connected the exposed pad area with the ground but currently I am not sure if its correct. There is not a word about what to do with it in the htt...
Posted on October 22, 2014 at 18:29Hello everybody! Where can I download a previous version of the stm32cubemx? A newest version has generation bug, the generated c files not working. The initalization paramater sets in the structures but the init f...
Posted on June 19, 2014 at 09:57I'm looking to drive an 800x480 LCD using an STM32F429 and the STemWin graphics library, due to the other peripherals needed from the chip, the SDRAM will most likely be limited to 16-bit. Could this be a serious perf...
Posted on November 05, 2014 at 20:30I need to have 2xSPI synchronized and also synchronized with some timers.Unusual use of TIM1. (STM32F401VC, discovery board)I use TIM1 in repeat and one pulse mode to generate 8 CLK for 1 byte of SPII have a worki...
Posted on November 01, 2014 at 12:03Hi all, I have issue with importing variables in to STM Studio 3.3. Import shows me only few variables (usually only uint8_t type), rest variables of different types (uint16_t, uint32_t ..) are not in list. Elf fi...
Posted on November 05, 2014 at 12:11Hi everyone! I have a project where necessary to use FPU to proccess my AD data. If I enable the FPU in the uVision Keil, then I can see an extra noise on my power line and I get wrong values, but when I disable ...
Posted on November 04, 2014 at 13:17I have problem when underclocking STM32F030. When I setup to RCC->CFGR2 higher value than RCC_CFGR2_PREDIV1_DIV4 (for example DIV5 - DIV16) then PLL is never ready ( RCC_CR_PLLRDY ) With value <= RCC_CFGR2_PRE...
