Posted on October 21, 2015 at 17:36Hello, I'm working on a project on a STM32F429 and we experienced every 10 or more days a board reset. Based on the fault handler I detect that somebody is wasting my memory but I cannot get who is wasting it. I le...
Posted on October 21, 2015 at 14:43 STM32f30x The aim is to trigger the DMA from a timer. The DMA should then send one row of data from my buffer to the SPI. The DMA should then trigger an interrupt which points DMA to the next row in the bu...

Posted on October 20, 2015 at 11:29gpioc pin 0 and gpio a pin 0 &1 work fine but gpio c pin 1 and furhter show 0.5v at output instead of 3 volts. here is the code i implemented &sharpinclude ''main.h'' static __IO uint32_t TimingDelay; //-----------...
Posted on October 18, 2015 at 23:29Hi all,lost one day finding that this line 259 from stm32l0xx_hal_gpio.c is missing some braces:bad (current):temp &= ~((uint32_t)0x0F) << (4 * (position & 0x03));right (should be):temp &= ~(((uint32_t)0x0F) << (4 ...
Posted on October 22, 2015 at 11:13Hi, thanks for your code .but I found that when transmit data use HAL_UART_Transmit, the lock of uart api will cause HAL_UART_Receive_IT can't receive data.how to slove it?

Posted on October 20, 2015 at 22:05Hello could you please help me with my question about backup SRAM in STM32F427? I have design, where I am using voltage regulator for VDD and VDDA - 3V0. As backup I use batery 3.2V connected to VBAT pin6. My qu...
Posted on October 22, 2015 at 00:24Good day everybody, I'm having an usual problem on STM32F407 SPI. I'm using a STM32F407 discovery board with a custom made breakout board (SPI2 pins used are PB13, PB14 and PB15 and are connected to a AD7190 AD...
Posted on October 21, 2015 at 22:02Hello could ypu please explain me how can I check from Order number of STM32F427VI which revision (HW revision) in this chip? In datasheet I can check, that for STM32F4xxx exist several HW revisoon of silicon chip:...
