Posted on April 20, 2015 at 01:44I'm using library only as a reference, so am writing simple test codes to understand guts of STM32F4xx. It is turn of SDIO.So far I'm able to read and write single block to SDHC card. My question to you is what shoul...
Posted on April 19, 2015 at 02:13Hello, I'm using a nucle 411 to test a RC servo driver. Si I configure 4 TIM3 channel to output PWM signal. Everithing is Ok, except that I can't finde a function to change PWM Duty Cycle. Is there any? BR!
Posted on April 19, 2015 at 15:58 How do I assign the variables a1 and a2 x ? I want to read the typed value unsigned long x; //readings value unsigned long a; //value unsigned int a1; //values written unsigned int a2; //values ...
Posted on April 18, 2015 at 23:12I can't figure out the cause of the Hard Fault: Chip: STM32F405RG Instruction (gcc generated program): vldr s0, [r4] r4 contains an address in the main RAM and aligned (0x2....4) Stepping over it results in a jump to...
Posted on April 18, 2015 at 23:58Hi,I am writing data on my sd card through spi in stm32f429zi controller using library of fatFs by chan. But after writing the data when i check the file it shows strange characters instead of the data entered. Later...
