I have a huge accuracy loss (way above what is expected in the datasheet) on ADC reading when increasing the sampling rate. I get that the accuracy is supposed to decrease but I sample at only 200 kHz on the STM32H47AI which is supposed to go up to 3.3MHz
Considering the fact that I can no longer make a difference between waveforms sent at 1kHz (sin and triangular) I am wondering about what I did code wrong in my ADC initialization to mess up my results that much. Below is a 1kHz sin I get for my 200...
How to increase the number of Zigbee nodes in the network?
I am using "stm32wb55rg" with FFD binary stack. Using Zigbee coordinator sample application example. With this I am able to join only 16 nodes in ZC network. Please suggest how I can increase the number of nodes that can join to the network.
Input Capture not consistent (STM32F103C6)
I'm using STM32F103C6T6 to capture input frequency configured on TIM2, Channel 1 (A0).I'm generating 1KHz frequency from Arduino Uno (using tone(Pin, 1000) function) connected to STM32 Pin PA0.Timer Configurations of STM32:Prescaler set to : 10000-1A...
Resolved! Problem with COMP1 and COMP2 as TIM1 break function sources.
Hi,I am using STM32L476. COMP1 and COMP2 are configured in window mode, and that is working great. I am also using TIM1 break function. Below is a summary of the problem that I am encountering:If I use COMP1, and only COMP1, as a source for BREAK or...
Resolved! I have two devices. Need to setup UART communication?
I have two STM32 devices and both are identical, send and receive messages in frame formats. They both have UART, DMA, NVIC etc. And I need a good strategy to setup a lossless communication between them. There is too much information online, but very...
HAL_RCC_OscConfig timeout
On initialisation SystemClock_Config(0 calls the function HAL_RCC_OscConfig() and this generates a timeout on the loop below: /* Set the new HSE configuration ---------------------------------------*/ __HAL_RCC_HSE_CONFIG(RCC_OscInitStruct->HSESt...
Resolved! UART Transmit Interrupt disable while keeping the Receive Interrupt alive
Hi all,I have a question regarding the control of the UART interrupt on the STM32F4.First let me describe the application:int main(void) { SystemInit(); //Stream out Data via Uart via DMA HAL_UART_Transmit_DMA(&huart2, (uint8_t *)UARTMessage_out,...
