ex) When compiled with IAR 8.30.1, HardFault exception was occured.float gfSetDataRate = 100.0f; printf("Data Rate = %f \r\n", gfSetDataRate);HardFault is occured at VCVT.F64.F32 instruction.I also tested following caseIn case Compiled with GCC, is...
Convert CubeMX project in Atollic to C++: Pane to input symbols for C++ missing
Hello,I am trying to convert a project generated by CubeMX to a C++ project in Atollic True Studio.From various sources, I got hints how to do. I fail when trying to copy the symbols e.g. processor type to C++ because the input pane is missing. Here ...
Is there a way to figure out what error the Cube32MX actually means?
Hi Folks, I recently had a hard drive crash so I had to re-install Atollic Studio and the Cube32MX programs. My original project was read by the Cube32MX just fine but when I clicked on the Generate Code button it'll chug for a while and this error p...

Resolved! Anyone have a working sdcard(FATFS) with DMA on the stm32f7?
Hey!I used HAL and I've tried to get the DMA going, although It doesn't seem to work and I'm not sure where the bug is at this point, I've realized that when I replace BSP_SD_WriteBlocks_DMA with the standard BSP_SD_WriteBlocks in sd_diskio.c the sdc...
Resolved! What is the endianess of STM32F407? Datasheet conflicts with real test.
I checked the data sheet of STM32F407 and it says it is little endian.However, when I test in a real device in MDK, it shows that it is big endian. I assign an int "testttt" as 0x12345678. Then, in memory window, it shows as 0x12345678 which is big e...
