Hi,I am using stm32f051r4 for my project . I want to configure multiple channel ADC using DMA and my configurations are as follows . void adc_configuration(){ RCC->AHBENR |= RCC_AHBENR_GPIOCEN; // Enable clock for used IO pins GPIOC->MODER |...
Posted on April 12, 2018 at 14:47I am using stm32f446zet6 and IDE keilv5 for a project . When debugging it shows the following error ,*** error 65: access violation at 0x40023800 : no 'read' permission*** error 65: access violation at 0x40023800 : n...
Posted on February 19, 2018 at 13:20We are using stm32f051r4t6 for a new project and the IDE is Keil V5 . We are generating an external interrupt on Pin PC2 . The hardware set up is a push button in pull down arrangement whose interrupt should occu...
Posted on February 15, 2018 at 10:59We are using stm32f051r4t6 IC for a new project and IDE used is Keil V5 . We are using Timer_3 running at 8MHz internal clock to generate a timer delay but , by varying PSC and ARR registers we always obtain near...
Posted on October 05, 2017 at 15:16Hi,We are facing a problem, any help will be greatly appreciated.I am using stm32f446zet. I have set to 180MHz system clock , but GPIO pin toggles at 8 MHz. We are using OPT8320 TOF sensor whose opclk runs at 24...
Posted on February 20, 2018 at 06:29When push button is in pull down arrangement and pull up arrangement , and when Rising trigger ( EXTI_RTSR) is enabled for input line, the interrupt occurs at both the cases .
Posted on September 14, 2017 at 06:25Sorry , ...void i2c_read(){ while(!(I2C1->SR1 & I2C_SR1_RXNE)); data = I2C1->DR;}waiting on while(!(I2C1->SR1 & I2C_SR1_RXNE));
Posted on September 13, 2017 at 15:11Thank you sir for your reply . I got the code for i2c write operation when i enabled gpio output type as open drain and when OR operation removed .But i couldn't readdata from rtc .Always data shows 0 .void i2c_...
Posted on September 12, 2017 at 13:50Why i2c data reception cannot be achieved from rtc in stm32f446. I can write data to rtc. I tried to receive data using hal driver but then also data reception doesn't occurs. HAL_I2C_Master_Receive(...
