Posted on May 23, 2015 at 11:34I have a board with a 32 bit SRAM and have used CubeMX to configure a 32 bit data bus, a 10 bit Address bus with a Chip select of NE1. Briefly, Cube has produced the MX_FMC_Init(); file with settings as follows:- hsram...
Posted on May 28, 2015 at 07:23i brought STEVAL-IEG001V2 from mouser with bulk id Z4T21418E002. but as mentioned in user manual i did not received any Firmware (code for microcontroller). kindly provide any link for firmware. Thanks
Posted on May 25, 2015 at 03:50 Hi, I'm running some tests on an STM32F072 to verify my understanding of the docs. Apparently I'm missing an important point regarding the NVIC and pending interrupts... I'm single-stepping through the code ...
Posted on May 27, 2015 at 20:24HelloCan DMA access SRAM at the same time the CPU is accessing it or vice versa?Thanks.
Posted on May 19, 2015 at 12:01I'm using the DALI library STSW-DALI001 but it doesn't memorize the DALI data in flash. The only data memorized is the assigned address from master module but all other, as SCENE or GROUP assignement are always reset t...
