Posted on November 09, 2017 at 10:11 Thank you for your patronage. I'm using STM32F3348-Discoverywhich has FPU and EWARM. I made calculations like the picture below. I'd like to check if floating point arithmetic is calculated correctly. So,...
Posted on November 09, 2017 at 13:35Hi all,I see an inconsistency between application notes.Here, AN4221 shows that all STM32F303xx controllers have I2C bootloaders:But if I open a different document (AN2606) I see that it is NOT true:Which is true?...
Posted on November 09, 2017 at 13:35Hi,I am porting my code from FREERTOS to RTX on stm32 nucleo platform,but once data transmission starts programs stucks with in second in hardfault handler because of the stack over flow, but if I put some delay b...
Posted on November 09, 2017 at 11:14Hi all,I have an application when I need to reserve 4Kbytes of memory. This size is fixed during the whole life cycle of my application.Therefore my first idea was to create a static memory allocation. But I also ...
Posted on November 09, 2017 at 11:19I'm having a problem on data logging.I use Chan's FatFs R0.08a, SDIO 1 bit mode, DMA and ST standard library, IAR compiler.I save 600,000 data per 200ms in SD Card using CSV format. It need about 33hours.If I try ...
Posted on November 08, 2017 at 21:05In the STM32F030X8 datasheet the PortB pin 15 alternate function AF0 is both SPI1_MOSI and SPI2_MOSI(see table 13 on page 35 of en.DM00088500.pdf). The pin 15 is just an example - there are more of such.How can th...
