Is there some issue related to ADC for NUCLEO_H743ZI or ADC configuration just missing in stm32h743_af. 5 cycles All these ADC are Time trigger for that i am using timer 1 as center aligned mode this timer will happen at every 20micro s In Cube I set up the ADC in Continuous Conversion Mode, Regular Conversion launched by software, and set the Conversion Data Management to DMA Circular Mode. All Pheriphera I'm attempting to get two ADC's to simultaneously sample on a STM32H743. ADC conversions are performed successively in a scan sequence. The ADC Configuration Will Be As Follows: All ADC settings will remain the same but we’ll need to enable the interrupt from the NVIC controller tab. STM32H743 PID lab Hello, in my project I connected 6 channels to ADC3; then i set up: A single mode regular sequence to read 5 of them using DMA; start of sequence is given by software inside a periodic task An injected sequence for the 6th channel to trigger a conversion when needed I want to use oversampling for Hi @wu qw , Are you using the indirect read mode? It is mentioned in the errata sheet ES03932, for the STM32H743 MCU , when the QUADSPI is configured in Indirect read with only the data phase activated (in Single, Dual, Quad or Dual-quad I/O mode), the QUADSPI peripheral hangs and the BUSY flag remains of the QUADSPI_SR register remains high. 6 Msps. 15. i am transferring the data to DM Find out more information: http://bit. In general, if p additional bits are required by the application, the ADC sampling frequency should be at least: F. The PLL that drives the ADC and also the internal switch that connects the input signal to the sampling capacitor is very jittery. Why would a presumably 12-bit ADC result in values larger than So now it is solved. Here is the code snippet of the configuration which I setting : The internal ADC of the STM32H743 is used for digitizing the antenna signal and the internal DAC of the STM32H743 is used for putting out the audio signal. While in the ADC setting, we have maximum sampling HAL_ADC_Start_DMA(&hadc2, (uint32_t*)&adc_buffer, 5); Leo H - July 19, 2022 at 12:41 pm. The RCC controller has a dedicated programmable Greetings, I am working on a project where a STM32H743 nucleo board and use of 16 ADC inputs are involved. Thus a 32b word holds 2 x 12b conversions. I don't know if I understand it this way, right? I want to collect higher-frequency sine waves. The code and the clock configuration are shown, and the answer suggests checking the ADC The STM32H7-application sends ADC data to the PC via USART3. Piranha. ADC has a clockfrequency of 48 MHz. Some applications require periodic sampling of analog signals using an ADC (Analog to Digital Putting the code together, the ADC seems to use the reference voltage properly in conjunction with measuring the temperature sensor. ) The Exact Same Steps As The Previous Example Except For Step 2. HAL library is quite straight forward and simple, while LL took me some time to make it run. Dllanes ADC gpio_adc="A0" adc=pyb. I'd assume adc_hclk is the clock of the AHB bus to which the given ADC is attached to; this based on the diagram where adc_hclk is the clock driving the AHB interface of the given ADC. If, it is the input for t 在高性能嵌入式系统中，高速高精度adc采样是数据采集的重要环节。stm32h743作为stm32家族的高端mcu，内置多个16位adc模块，采样速度高达3. Staff member For it to work, I have to calculate the charge time on my capacitor. (Read 1195 times) 0 Members and 1 Guest are viewing this topic. Issue #2: Radc not specified in I can read ADC value from ADC1_IN1 channel with this code ADCValue = HAL_ADC_GetValue(&hadc1); but ADC1 port (you can see on picture) has many channels. This avoids unnecessary conversions and thus reduces power consumption. According to the aroma sampling principle, the maximum sine wave frequency that can be collected is 1. The issue is my ADC doesn't measuring from zero, when my GPIO pin is reset, the values that I'm getting are around 0. Observing ADC_ISR bit ADRDY, it looks like ADC is not ready at all. 3. Also note that if the continuousconversion mode is disabled, ADC will stop here and we have to again start the conversion in interrupt mode. But using ADC1 or ADC2 I mistakenly thought that the ADC used a 32 bit data register and it does - just not for a regular single channel mode that I'm using. In chapter 6. 0 ADC Clock settings were removed for some reason. I am working on a project where a STM32H743 nucleo board and use of 16 ADC inputs are involved. I am not so sure about this setup will work using ioc: On the other hand, I have tried with different setups, like Independent Hi all, recently I am trying to use ADC to sample 4 channel current signals. The Cube example is the ADC_AnalogWatchdog which use several feature ADC, DMA, watchdog for the Nucleo F103RB. External high density RAM up to 8 MB connected across 133MHz QSPI bus accessible in memory mapped mode or block device mode with on the fly encryption/decryption. And because the clock I used is adc_sclk, so no DIV in ADCx_CCR register has effect on sampling frequency - that was probably main mistake I did. gctfnhosxqjhcdwwrisntxviwsgbzwnyidauzpnvjnjgipyw
