Hi all,I am trying to interface a STM32L073RZ to a Si2151 tuner IC using I2C. I keep getting HAL_ERROR everytime i use the HAL_I2C_Master_Transmit function. I used STM32cubeMx to set the I2C parameter settings (freq to 400K) but the generated code ha...
I have used NUCLEO-F072RB EVK and just print "Hello World" using printf function but didn't print anything on console.IDE : STM32CubeIDEMay I know How to use printf function with proper steps?Please find below code : #################################...
Does load capacitance matter for a given device? Or does that only effect the caps you pair with the oscillator?
Hi,I know that PSSI can be used to transfer data between two STM32H7 microcontrollers. I wonder if there are other uses for PSSI?Are there any other components that use this interface?
Hi, I have 3 interruption pins PA13, PA14 and PA15, I would like to enable one pin for interruption at a time and changing the interruption mode, I made this function, but I'm not sure if it's the right way to achieve that.void Switch(uint16_t PIN, u...
I am using NUCLEO-STM32H743ZI2. I try ADC3 + DMA, but I confuse ADC3 CLOCK, from cubeMx, I found THERE ARE 3 SOURCE (PLL2P,PLL3R,PER_CK) for adc clock, in manual, it mentioned SCLK and HCLK can be clock resource as well. In RCC adc clock selection, o...
In my project I need to add padding to few flash address. I generated hex file which has flash data till 0x1000(Suppose) but I want to pad till 0x4000 with 0xFF. I am using below gcc commands but unable to get desired output.arm-none-eabi-objcopy --s...
In my debugging, I noticed something wierd with this line of code from HAL_SPI_Transmit macro :hspi->Instance->DR = *((uint16_t *)hspi->pTxBuffPtr);pTxBuffPtr being the Transmit Buffer which, in my case, is txBuff[1] the first element of a one-elemen...
Hi,i am using STM32F334C6T.i try to set my PWM as Center Aligned mode and generate interrupt at counter overflow. my code as below.whatever i do in my code, i can not take just one interrupt which is counter overflow. everytime it generates two times...
Hi ST Community,I am using the RTC on the STM32l100RBT6 µC to display the date and time every hour. It is battery powered and therefore at some point i would have to change the batteries, therefore, the µC will lose power. I have thought of using the...
