Posted on April 03, 2013 at 14:19Hi friends, It is written at ref/man for F2 and F4:Bit 7:0 I2SDIV: I2S Linear prescaler I2SDIV [7:0] = 0 or I2SDIV [7:0] = 1 are forbidden values. Why ''0'' is forbidden is clear, but why ''1'' ?! I make some intensi...
Posted on April 04, 2013 at 11:52Hello,I'm new to embedded programming and having a hard time getting into using the STM32L-Discovery. I'm trying to use the RTC to display time on the LCD on the board, I've been reading the documentation but haven't...
Posted on April 03, 2013 at 21:46HI, I'm going to extend my project with TCP/IP stack. What do you think is a best choice for TCP/IP stack. Currently I'm hesitating between lwIP and uIP. I'm developing under yagarto. Currently my code runs FreeRTO...
Posted on April 05, 2013 at 03:40Hi guysI want to do an experience with stm32f4.I want to simulate AM(amplitude modulation).I want to use 168 MHz as a carrier and generate the data in 100 khz. and modulate this 2 waves together.this action like i pu...
