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 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?
