I am wondering if VSSA voltage can be slightly lower than VSS? If so, what is the maximum allowed difference?The reason why I ask is because I would like to measure voltage slightly (0.2-0.3V) below the common ground attached to VSS. I looked in seve...
I need a MCU with a USB host controller. It seems to be hit or miss as to which STM32 chips have this feature. I've tried the product selector on both this site and Digikey, but "host" is only ever listed in the datasheet, so this has proven fruitles...
Hello Team,We are trying to configure Nucleo-l476rg with 74HC165B1 with SPI Parallel IN SERIAL OUT but unable to configure the board, Kindly help me with code with any other STM microcontroller in STMCUBE_IDE OR KEIL. Best Regards,Gagan Gowda G
I want to drive a WS2812 LED strip using PWM and DMA. I've tried everything, but it's not working. I'm running at 72MHz, and I'm using htim2.Init.Prescaler = 0; and htim2.Init.Period = 90-1;. This is how my library works./** wsled.c** Created on: Ma...
Hello STM team,I'm working with STM32h745 project. in that interface 7 external ADC using SPI and I want to continuously read ADC data and send using serial usb. So now my function executed one by one sequential manner but Some ADC data loss. So I wa...
Hi there,I am using the touchGFX and I want to store my image to SPI flash chip.The pin to pin of the connect as below:STM32F429BI <---> W25Q64BVSSIG CS <---> PD13 CLK <---> PB3(SPI3_SCK) DO <---> PB4(SPI3_MISO) DI ...
I'm using CubeIDE and I want to have an output compare event on TIM1 CH1 trigger an input capture event on TIM8. It doesn’t seem like there is a way to do this with normal timer functions and CubeIDE. Is it possible if I work outside CubeIDE?As a bac...
Hello all-Working with the SPI peripheral on the STM32F411VET6, we need to connect to a device that sadly requires the CS line to toggle with every byte sent. Just about every example code runs along the logic of "write to the SPI data register and ...
Hello,I need to drive some power mosfets (STP55NF06) from open drain outputs.The gate and mcu output will be connected to a pull up resistor to 12VAre the TT and FT pin voltage limits applicable when used in open drain mode?If yes, I will amplify the...
I’m using CubeIDE + STM32G4 to configure DMA transfers and I’m a bit confused by the interrupt code it generates. Configuring DMA transfers on TIM8 defaults 'DMA1 Channel1 global interrupt' to enabled and generates a DMA1_Channel1_IRQ_Handler functi...
