Posted on April 04, 2013 at 17:37Hi all, When I supply 2 of my ADC inputs with 3V ramp/triangle/sine waves, it seems that values from 1024 - 1048 are reporting as 1023. There is another smaller ''dead band'' from 1087 up to 1092. Everything e...
Posted on April 03, 2013 at 11:27Hello, i run in to a problem, where i need to do math with single precision floating point. it looks like if(...) condition, and printing floating point to uint16_t is very slow. so i have two questions: first, what ...
Posted on April 04, 2013 at 15:51Hello ST lovers,I have a very simple yet critical to my project question : is the RAM in the STM32F405 erased upon reset ? If yes, then is there any EEPROM I can use to store 32 bits of data that'll survive through r...
Posted on April 04, 2013 at 14:43I have problem erease the write to the FLASH . I do as follow FLASH_Unlock(); FLASH_EraseSector(FLASH_Sector_4, VoltageRange_3); Prair to that I check that all section are unlock nWRP= 0xFFF. I use HSE and I ...
