Posted on June 01, 2015 at 19:36 Hello everybody, I have a strange problem, hard to debug, I want to know if somebody already had this kind of ADC madness. I use 6 ADC inputs in my code, using DMA and NVIC. Sometimes, after 2 to 5 m...
Posted on June 05, 2015 at 09:13HiOnce we jump to bootloader of STM32 controller for Firmware upgrade(DFU mode),the Windows7 64 bit OS was not able to install driver automatically(However it worked in 32 bit OS). IS there any link or place where w...
Posted on June 04, 2015 at 22:37 I am trying to use pb8 and pb9 with stm32f4 's usart 2 peripheral.I first used usart 2 with pb6 and pb7.It worked great but then i was obliged to change them. to pb8 and pb9. Here a quick look at my code. ...
Posted on June 04, 2015 at 17:01Dear community,I am trying to initialize the UART of the STM32F051 µC – however receiving of data does not work because the interrupt is not triggered. I recognized only the weak initialization of the UART1 interrupt ...
Posted on June 04, 2015 at 06:39Just got a STM32F429 Discovery board and am seeing something weird when implementing an SPI driver in master mode. I'm writing the SPI driver code from scratch and am not using a peripheral library.The SPI peripheral ...
Posted on June 04, 2015 at 01:18 Hi, I'm continue fighting with full-duplex configuration of STM32F4 I have an audio codec with MIC input and speaker output. I connect DOUT pin from the CODEC to PC3 (I2S_Dat) line. So it will be my Rx pin. Th...
Posted on June 04, 2015 at 09:39I'm using a stm32f303 which has a max clock speed of 72MHz. It would be very convenient for me to set it to 73.728MHz. It works on my board, but what effect does a few percent overclocking have on the MCU? How is rel...
Posted on June 04, 2015 at 20:28I can't find the internal oscillator accuracy anywhere in the datasheet or the reference manual. If I have the sysclk set at 48MHz from the internal osc. what are the limits of what that sysclk may actually be? #da...
Posted on June 04, 2015 at 22:00I'm trying to get an ADC input to work on the Discovery STM32L053 board. The VREF calibration value is 0x68D, reading channel 17 shows 0x5E9, which by my calculations makes VDD 3.325 volts, which matches what I read o...
Posted on May 29, 2015 at 02:55Hi,I am developing codes on STM32L0 microcontrollerI want to add flash read out protection function in the code.After I enable the PcROP(proprietary Code Read Out Protection), my codes do not work anymore. It does not ...
