Posted on December 16, 2014 at 14:15My company has developed a board with a STM32F207IG and RMII ethernet which is working fine. Now they have given me the same board with a STM32F439II fitted, and here I can not get the ethernet to work. The CPUs s...
Posted on December 15, 2014 at 16:52Hi, I am using STM32L152. I programmed some timers to output a repeated burst of pulses without any software interaction. Now I want SPI to transmit data from a buffer, one 16 bit word at each pulse, and repeat th...
Posted on December 15, 2014 at 02:55Hi,How can i link 2 different hex files at 2 distinct memory locations?for example at 0000h i have my main code and at 4000h i have my application code. app code must access the functions in main code, so since i ...
