I'm faced with connecting a (piano) keyboard to an MCU using a number of columns and a number of rows.The principle is shown in the attached photo. I've read approaches where the coulmns are pulled to low while the rows are inputs that are sensed.Am...
Hi, I am looking for a microcontroller in the STM32F103 series or a similar Cortex-M3 series for my satellite research. I need a specific type (full part number would be best) that has been used on a satellite that has already flown in space. Thank y...
Hi everyone,I’m working on a battery monitoring prototype using an STM32F303. I’m measuring multiple analog voltages using the internal ADC with DMA. The ADC readings fluctuate by ±20 counts whenever the PWM output for the buck converter is enabled.I...
Trying to Interface ADS1293 with STM32U5 for 3-Lead ECG – Need Help with Lead II Data Hi STM32 Community :waving_hand:, We’re trying to build a 3-lead ECG signal acquisition setup using the ADS1293 analog front-end connected via SPI to an STM32U5G...
This is probably an old hat to most of you here but I'm facing this problem momentarily:Using an STM32F103CBT6 (Blue Pill) where GPIOB Port is used already with the following PB3 - SPI1_SCKPB5 - SP1_MOSIPB6 - Some Interface Function (OUTPUT)PB7 - Som...
Hi I am trying to use the AEK-POW-BMSWTX to read cell voltages from an Optipower OPR50006S50 Lithium Ion battery. I only want the cell information, not interested in battery management itself. I'm using SPI2 from an STM32G474RE. I have spliced pin ...
hello ST Community, I'm trying to send commands as indicated in the AN3155 manual via UART with Teraterm on the NUCLEO-H755ZI-Q for CM7. system bootloader application note (AN3155) First, I tried establishing UART communication with the STM32CubePro...
Hello everyone,I am a research scholar in High Energy Physics and currently working on a scintillation-based muon detector using SiPMs.My setup:- Board: STM32 NUCLEO-F446RE- Sensors: 2 SiPMs- Signal conditioning: Op-amp amplification + peak detection...
Hello.I am trying to implement RFID using NXP's NT3H2211W0FT1. The microcontroller I am using is the STM32C031F6.After powering on the board, the first thing I do is read the data from the NT3H2211W0FT1 via I2C, but sometimes I can read it and someti...
Hi, I'm relatively new to STM32 series and so far have experience with STM32F103 only. My current goal is to learn and work on master-slave system, with master being an embedded linux (IMX6ULL), and the slaves are (supposingly) STM32 boards. Cameras ...
