The information in RM0433 regarding the use of the WBNE flag with respect to flag operation is unclear. In DocID029587 Rev 3, page 148/3178 it states:"WBNE1 is reset by hardware each time the write buffer is emptied. This happens when oneof the foll...
Posted on July 16, 2018 at 15:54Hello!My name is Jason.I have been testing USB FatFS of STM32F4-Discovery board since last week.And I tested reference source code of STMicro.(STM32Cube_FW_F4_V1.21.0\Projects\STM32F4-Discovery\Applications\FatFs\FatF...
Posted on July 08, 2018 at 10:35Hi.I want to generate a PWM pulse which might vary in terms of its frequency and duty cycle. It's easy to make it But I want to start reading ADC values using DMA (for example 100 samples) just after the pulse finishe...
Posted on June 04, 2018 at 22:36Hi.I tried to port latest SBSFU to STM32L4+ line of MCUs using NUCLEO-L4R5ZI board.I modified preprocessor macro to STM32L4R5xx and I found such problems:1. FLASH_PAGE_SIZE for L4+ is 0x1000, while for L4 it is 0x0800...
Posted on June 13, 2018 at 14:38I'm having trouble to initialize the LoRa stack after standby mode. I'm saving the required keys after the first join request etc on the EEPROM. But after standby mode, the stack needs to be initialized again. But I w...
