Posted on August 19, 2015 at 15:02Hi,I have encountered the following problem on the STM32F4 using the CMSIS DSP Library V1.4.2:When calculating the standard deviation using arm_std_f32() of the following values </colgroup> 7111.15283 7111.3867...
Posted on August 19, 2015 at 20:18Hello, I made a PCB with a STM32F429IGT6 (f429 176 pins) and I want to test it but... I cannot flash my stm. I've tried many things and I'm started to think I might have missed something so if some experienced stm32...
Posted on August 20, 2015 at 11:49Hello,i'm using the HAL library and CubeMx. The chip is a STM32F334C8.I want to send datas on USART1 with DMA control. The datas are well sent but when i go to the DMA complete transfer interrupt, i wait in the inte...
Posted on August 19, 2015 at 21:34Is there a general programmer reference available for the STM32? For example, basic functions like Delays, Timers, GPIO, PWM, etc?
Posted on August 19, 2015 at 13:09Hi, I am trying to connect to the bootloader on nucleo -F070Rb board. I tried the Flash loader Demonstrator, but I get ''No response from the target...''. I tried to send the start comman byte (0x7F) using realterm ...
Posted on August 18, 2015 at 20:59 On an STM32F4 Discovery (STM32F407) I'm trying to set up a timer and then reconfigure it within its own interrupt handler. The idea is that I should be able to repeatedly trigger tasks from the ISR in an...
Posted on August 20, 2015 at 09:14Hello. I'd like to know what microcontrollers has qspi interface? Whole STM32F7 series? The document DS10916 says that ''All STM32F75xx devices embed a Quad SPI memory interface, ...''(2.9.Chapter) but there is no ...
