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...
HiI want to use TIM2_CH1 as the timer_2 input capture and also use this pin to trigger timer 2 to start counting.here is the code I use for configuring it:static void MX_TIM2_Init(void) { /* USER CODE BEGIN TIM2_Init 0 */ /* USER CODE END TIM...
I would like to be able to use USART2 in RX mode only, but even configuring it as Receive only still takes over the SYS_SWCLK pin (with alternate function USART2 TX). I am never going to use the TX pin, and I'd like to use SYS_SWCLK for flashing and ...
