Posted on November 10, 2017 at 05:42 Hi, I used STM32F103 MCU before and was new for STM32F3x MCU. My stm32f103 codes was migrated to stm32f302 codes for stm32f302r8 MCU.The code problem is that after power on, MCU turned on LED normally and prin...
Posted on November 10, 2017 at 23:09I'm working with a Nucleo F767ZI and BSP F7 V1.8.0.When setting up a pair of ADCs to do dual simultaneous conversions, DMA access mode disabled and mode 2 are the only choices. Access mode 1 and 3 are missing fro...
Posted on March 28, 2016 at 23:29Recently the STM32F407 discovery board changed part numbers from STM32F4DISCOVERY to STM32F407G-DISC1. The old boards could be powered directly via the 5V pins on the headers, or via a USB wall-wart, but the new boar...
Posted on November 10, 2017 at 18:54Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed. How to Fix Code 43 Errors for STM32F407G-DISC1 MCU?NOTE: MY BOARD IS STM32F407G-DISC1I H...
Posted on November 10, 2017 at 13:18I am accessing an illegal memory location, but it does no generate MemManage fault or HardFault. Here's the compiling code that demonstrate the issue.&sharpdefine SCB_SHCSR (*((volatile unsigned long*) 0xE000ED24)...
Posted on November 10, 2017 at 21:03Hi, I need to calibrate my RTC crystal that is drifting about 7 seconds every 18014 that according to my calculations is about 389 ppm. I Tryed to perform the calibration with the following initialization code, bu...
Posted on November 10, 2017 at 18:21I have an STM32F103C8T6 uC and an ASIC chip with memory. They communicate with SPI interface, ST being the Master device. On the uC lies a Firmware by the vendor of the ASIC device. I have been trying to shape it ...
Posted on November 09, 2017 at 15:07Hi,i use a STM32L496.I configured the SPI to communicate 8bit but it always generates 16clk e 16bit data.SPI : MASTER- halfduplex 2wire(1clk , 1Mosi/Miso) /* Enable clock for SPI2 */ RCC->APB1ENR1 |= RCC_APB1ENR1_...
Posted on June 28, 2017 at 13:34Hello. My application hangs after setting the ROP to LVL1 and resetting the whole device. I have found some people had this issue as well and power cycling helped (which is my case as well). But it is kind of an incon...
Posted on November 10, 2017 at 14:09Hello, I'm working with STM32F4 Discovery Board and trying to generate a 16-pulse signal with variable duty cycle like this on the picture below.Currently i can generate 16 Pulse through One Pulse Mode. However i ...
