I am interfacing (IS66/67WV51216EBLL) 8Mbit static RAM organized as 512K words by 16 bits with STM32F723 microcontroller using it’s inbuilt FMC interface. FMC is configured in 16bit mode. Read and write operations are working as expected. Bu...
I want to use ADC1 and ADC2 in dual mode simultaneous. In reference manual on p.360 there is a note that states that i can't convert tha same channel on both ADCs simultaneously ("no overlapping sampling times for the two ADCs when converting the sam...
Program locks in waiting for ADC_ISR ADRDY to become a '1'. Have set RCC_AHB2ENR bit 13 (ADC12EN), Cleared ADC2_CR-bit26(DEEPPWD) and set ADC2_CR-bit25(ADVREGEN). Finally set ADC2_CR-bit0(ADEN). Now ADC2_ISR bit-0 (ADRDY) should become high, but it s...
I want to read an image from an android phone via usb. Pl suggest me some microcontroller
Hi There,I Have purchased(On transit :) ) NUCLEO-F030R8 board for learning purpose. I''m planning to use Kiel IDE. Is this board needs separate debugger ? Or just usb cable connected to PC from board does the Job ?Thank you.
I have a simple application with the goal to fill a ring buffer with bytes received on the uart, while always transmitting 'E' at the same time. The UART uses both the RX and TX FIFOs. The only code running in the main thread is :uint8_t data = 0x45;...
Posted on March 29, 2017 at 00:21I've been working with USB on my Nucleo board(S) for some time now. Been comfortably successful at getting a few operational interfaces working with it. Including DFU. STM32L476. So time to make our own PCBS! We kno...
I have configured my ADC to convert an analog value every 100 milli seconds using timer 2 , I could able to write data to EEPROM but while reading it back i could only see 20 variables in array. As below mentioned in code, I could able to switch on m...
RM0091 rev.9 in 25.7.5 RTC prescaler register (RTC_PRER) says:The initialization must be performed in two separate write accesses. Refer to Calendar initialization and configuration on page 584.However, Calendar initialization and configuration doe...
