Resolved! STM32H743ZI ADC + DMA sampling data acting quite strange
Hi everyone, hope all of you are doing well.Posting here again about the ADC. I finally got the ADC out of that over run situation and now ready to acquire data!The way the ADC is setup is by having 4 channels using Pins setup as continuous scanningP...
Timer 2 Nucleo L476RG
I am using the above Timer as both a debounce of 50ms and as a PWM for the on board LED. Basically I hit the user button, debounce for 50ms. While button held PWM to the LED of 1/2 sec on, 1/2 sec off.....Release button and PWM stops.The timer is run...
Resolved! Counter? Nucleo L476RG
Can someone tell me when I useuint16_t temp; temp = __HAL_TIM_GET_COUNTER(&htim2);the above why temp doesn't equal the TIM2 CNT register in the debugger? I've also triedtemp = htim2.Instance->CNT;
Resolved! STM32F40G UART, unexpected pulse on Rx Line
I am sending some data on UART, When I enable Transmitter TE bit in USART_CR1 register, a pulse is observed on Tx line ( as shown in figure). That's fine but I am observing some 190nsec pulses on Rx lines though I am not sending anything to it! I hav...
Resolved! STM32G030 ADC voltage residual issue
Hi Almighty Internet & STSo huge learning curve using MCU STM32G030J6 with ADCLearned the hard way you cannot use pin 4 for ADC as this is shared by NRST and there is no way to turn off MCU resetting because the bit registers which exist in STM32G031...
Resolved! STM32F4 problem receiving 0xF8 over UART with HAL
Hello I am trying to send hex values over UART with HAL_Transmitin the cubeIDE I do:HAL_UART_Transmit(&huart2,(0xF << 4) | (0x8), 1,10);However I receive in Hterm0xC5I cannot make sense over it. Sending text with " some text" works fineHAL_UART_Trans...
how to make DAC hold stable output voltage
I am testing OPAMP_PGA example code.Here is the DAC config code: /** DAC channel OUT1 config */ sConfig.DAC_HighFrequency = DAC_HIGH_FREQUENCY_INTERFACE_MODE_AUTOMATIC; sConfig.DAC_DMADoubleDataMode = DISABLE; sConfig.DAC_SignedFormat = DISA...
iOS app: will not work with STWINKT1B
I wanted to make sure the dev board I received would work before the webinar, but unfortunately I have not been able to reproduce the steps as seen on the YouTube tutorial. It seems like the iOS app is out of date according to attached screenshot.
How to program STM32F103RE on Creality v4.2.7 silent 3D Printer board [solved]
I have written an open source 3D Printer firmware for Arduino Mega - RAMPS 1.6 board which i have uploaded to github: https://github.com/3DHexfw/3DHexNow i am trying to port the code to Creality v4.2.7 board (STM32F103RE on board). To do so i have do...
