I want to send 16-bit, 16-channel data measured by ADC. but I realize BLE is transfering 8bit data. How can I solve this?my key script is below.<main.c>uint16_t DMAo[16]; HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED); HAL_ADC_Start_DMA(&hadc...
I am producing a prototype and will not be making a custom PCB therefore I need to try to reduce power consumption of a Nucleo-STM32H7A3 development board.With the microcontroller in standby mode (approx. 3uA) the dev board itself consumes 6mA runnin...
I am trying to convert time dominie to frequency dominie to calculate FFT of that data. If so, who can I do that.
I'm using an STM32L4 for a solar inverter control project to control some H-bridges and sense some voltage and current. I run into this particular issue that when the environment is noisy (the DC input to the H-bridge is high), the ADC sometimes will...
TIM20 peripheral is missing in the SVD file for STM32G491 deployed in Keil PACK STM32G4xx_FDP v1.4.0Please see the attached fix with all files rebuilt (SFR and SFD)
Hi everyone,I'm working on STM32L433 Nucleo-64 board and I would like to try the low power sleep mode to see the power consumption part.From datasheet, current consumption us XXuA. Use my example code, the current consumption(PIN is JP6) is about 5....
I am using an STM32L4 chip that sends an update to the nRF52832 on a ublox module over USART. I assume the nordic chip is in the bootloader during the update.We get a UART error: 4 and when we observe the UART lines we see that on the TX line of the...
I have to replace HAL(ADC) with self made implementation (regular channel, 1 channel, single conversion).During that, i found that delay between setting of ADON and SWSTART (Tstab) is significant for the quality of the measurement (stm32f4xx_hal_adc....
I would like to use SAI interface, but the initial setup seems to be failing. ErrorHandler was called because of FIFO is Empty after calling HAL_SAI_Transmit_DMA().The SAI is set up as follows: hsai_BlockA4.Instance = SAI4_Block_A; hsai_BlockA4.I...
