Posted on May 20, 2012 at 20:02 The input to this function is a 'Desired Frequency' and the function, fairly quickly locates (out of the 4 billion possibilities! (ARR(16bit)*PSC(16bit)) the correct values for a given TIMER'S PRESCALER(PSC) and P...
Posted on September 30, 2014 at 21:29Hello,I've been racking my head trying to make sense of how to correctly configure the I2S Hardware to interface with the MP45DT02 microphone. I've been looking at ST's waverecorder.c for inspiration but I think ...
Posted on September 13, 2014 at 01:46I am having troubles setting up IAR Function Profiler so I wanted to double-check: The grey ''ST-LINK/V2'' device vs the debug interface within discovery board. Are these the same exact thing? At least my Windows...
Posted on September 17, 2014 at 09:35Hello. I am working in a R&D Project with the STM32 MCU. I have implemented Ethernet functionality like examples provided by ST. Frame transmission and reception are OK (checked with Wireshark). Now I must add PT...
Posted on September 19, 2014 at 17:18I'm designing a USB microphone, using STM32F0. All of the reference or example codes I can find are for USB speaker, and further more, they support only single sampling frequency. Is there anybody can provide any...
Posted on September 30, 2014 at 12:11Hi, I'm using an STM32L051 microcontroller for a low power application. Actually I am working on a state change between low power and normal operating mode. Therefore I am trying to switch the system clock to PLL...
Posted on July 24, 2013 at 09:47Hi,Until yesterday I haven't got any problems to launch my code into flash memory with CooCoxIDE. STLink utility and STMStudio have worked well also.But this morning, I can't do all thius things :C:\CooCox\CoIDE>''C:/...
Posted on September 26, 2014 at 00:43 Hi, I am having issue with the USART interrupt handler in my project. It seems to get stuck in the interrupt handler routine. The status register value is set to 0x1d8 but I don't seem to be able to ...
Posted on September 13, 2011 at 09:10Sometimes my code gets lost in usart1 interrupt flood.Registers:CR1: 0x202c (UE, RXNEIE, TE, RE)CR2 = 0, CR3 = 0SR: 0x1d8 (LBD, TXE, TC, IDLE, ORE)I'm not quite getting it how ORE can be set and RXNE not. The onl...
Posted on April 18, 2013 at 14:13Hello everybody, I have a board with stm32f207 and I use GPIO_AF_OTG2_FS as USB device connection, and I have sometime a strange problem when I plug the USB cable. When I plug the cable, all is working correctly and ...
