STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on March 26, 2013 at 17:15The Reference Manual states ''The internal PLL can be clocked by the HSI RC or HSE crystal.''Is it possible to clock the PLL by feeding an external reference into OSC_IN?If there is no signal present at OSC_IN will t...
Posted on March 28, 2013 at 12:14Hello, sorry for maybe stupid question, but I can't understand - how to make the frequency divider using STM32F4's timers? I mean how to divede the frequency of the external signal and output it from CPU? Tnanks. ...

Posted on March 28, 2013 at 10:12Hi, in the file System_ST32F4xx.c of the ST4Discovery examples, I always find the following 2 lines for the clock configuration (SysClk 168MHz): /* HCLK = SYSCLK / 1*/ RCC->CFGR |= RCC_CFGR_HPRE_DIV1; ...
Posted on March 28, 2013 at 15:40 Hi, I have STM32F4 Discovery connected OV9655 camera module without using any external ram from LCD.I want to use PC interfaces in the other words from DMA to Usart2 Module.I have tested it in many ways from...
Posted on March 19, 2013 at 14:47Hello.I found the USB HID Demonstrator application. I want to test it with my STM32F4 Discovery board. But i don't have any code in the microcontroller to communicate with this application. Can anyone help me to find...
Posted on March 28, 2013 at 12:50As I look in ST example I didn't find any example for saving to the OTP. If there please link me to. Only found this function FLASH_Status FLASH_ProgramOTP(uint32_t Address, uint32_t Data) I go threw the flash prog...
Posted on March 27, 2013 at 23:32Hello all,I will apreciate any help that can give me some light to understand what is happening.The firmware has a loader, data flash and an application.ROM memory mapping:* Loader 0x0000h - 0x3FFFh* EEPROM DATA 0x...
Posted on March 28, 2013 at 07:12Hi, I have to know whether how much amount of program memory will need to debug a Embedded linux in controller as well as needed RAM size to load the linux application. Am new to this platform, So could you plea...
Posted on March 27, 2013 at 21:57Hi, Trying to get my head around how many ADC channels that are available in STM32F207Zx chip. Datasheet p14 Table3 claim ''Number of channels = 24''. Also on p.1 ''ADC with up to 24 channels''. OTOH, Reference manua...
