Posted on September 13, 2017 at 16:56In my situation, I need to do SPI receiving with DMA (master side), and not care about Tx. I have three choices in the STM32Cube: Full-duplex masterHalf-duplex masterReceive only masterAnd I have two choices for...
Posted on September 13, 2017 at 16:05I'm using SPI with DMA for both Tx and Rx. So I call the relevant HAL API : 'HAL_SPI_TransmitReceive_DMA()'. And I only want to response to the Rx complete event. I find two possible places to filter the event: ...
Posted on September 13, 2017 at 15:55HelloWe are using FMC for communication with FPGA. FPGA has memory-mapped periphery implemented in compatible mode for synchronous non/multiplexed PSRAM/NOR.We are facing problem with misinterpreted spikes/cut pu...

Posted on September 13, 2017 at 03:08First Question . I am first time user of STM and I am totally new to STM. My idea is to build a GPRS GSM STM module as a gateway for various Automation project. Kindly let me know where should I start about the e...
Posted on September 13, 2017 at 14:09I just found this out on electronics stackexchange:If you set the struct member NVIC_IRQChannelCmd = DISABLE, calling NVIC_Init() will do nothing to set the interrupt priority and sub-priority. If you want the in...
