![]() Pricing and Availability on millions of electronic components from Digi-Key Electronics. The final implementation of the project will be on a STM32U595, which apparently has a different datasheet from the STM32U575, and I noticed that only after facing this problem.Īs far as I can understand from the STM32U575 datasheet on the ADC characteristic, silicon rev X has some lower performance on ADC compared to the STM32U595, but still the Differential linearity error I'm measuring is way too big. NUCLEO-U575ZI-Q STM32U575 Nucleo-144 STM32U5 ARM® Cortex®-M33 MCU 32-Bit Embedded Evaluation Board from STMicroelectronics. Using ADC4 ( 12bit) gives no problem ( see picture ) HAL_ADCEx_Calibration_Start makes no difference ![]() Tested two different application code, one based from scratch application and one based on "ADC_SingleConversion_TriggerSW_IT" example, with same result NUCLEO-U575ZI-Q STM32U575ZIT6Q 32Bit, Arm Cortex-M33 Development Board Common features STM32 microcontroller in LQFP144 package 3 user LEDs 2 user and. The STM32U575I-EV evaluation kit comes with a camera module, sensors, and a display, to prototype more powerful IoT. Moreover, in the coming weeks, two more development boards will hit the shelves. ![]() Engineers can use it with sensors and communication boards to build applications. Tested with VREF tied to 3V3 or with external reference without any difference. To get started, teams can already grab the NUCLEO-U575ZI-Q. STM32 Nucleo-144 development board with STM32L552ZE MCU, SMPS, supports Arduino, ST Zio and morpho connectivity. STM32CubeIDE Version: 1.14.0 Build: 19471_20231121_1200 (UTC)ĪDC is read in software trigger mode with ADC complete callback interrupt, tested different configuration, different resolution ( 14bit 12 bit ), clock, single ended or differential, oversampled or not, on different channel, but linearity error is always present. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation. Prices and availability in real-time, fast shipping. Order STM32 Nucleo Boards:NUCLEO-U575ZI-Q direct from STMicroelectronics official eStore. &127877 Flat-rate shipping is live - Only 5.99 worldwide delivery until Dec. Test on evaluation board NUCLEO-U575ZI-Q, NUCLEO575ZIQ$AT2, marking on microcontroller is "X" For the best experience on our site, be sure to turn on Javascript in your browser. See pictures below for a better view of the issue. This happens at spacing of about 500 points all along the input range. In some point of ADC1 range there is a huge gap between sampling points, Differential linearity error is around 25 LSB, clearly out of spec. I'm facing an issue in reading ADC1 on a NUCLEO-U575ZI-Q evaluation board.
