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 ...
Posted on June 18, 2014 at 20:24Could someone please confirm the following issue ?, p.706/914 states that: ''ORE: Overrun error (...) An interrupt is generated if RXNEIE=1 or EIE = 1 in the USARTx_CR1 register.'' The hardware indeed appears to work ...
Posted on September 29, 2014 at 23:16 Hi all, I've been getting familiar with the RCC stuff on the STM32L152 (STMrecently152L-Discovery), but I'm struggling to push the baud rate of my USART transmission beyond 130Kbaud. I've set u...
