Best way to sequence ADC (a lot) without DMA

Hi all, I'm building an application which needs to sample 8 ADC channels at roughly 10kHz, while listening for messages over SPI. The issue I'm facing is that neither of these can be missed, and sometimes they occur simultaneously. Ideally both of th...

Problem trying to generate pwm by configurating the pin pb10 as open drain.

Hi, i`m having an issue driving a mosfet(irfz44n n channel---it`s a boost converter from 12v to 42v dc), the thing is that i`m usnig a PWM signal of the stm32f103c8tx, when it`s a %50 duty cycle i`ve got around 1.6v aprox, it`s not enough to power th...

Hello,I'm working on STM32l051K8 MCU with the custom board design. I just wanted to enter the device to the bootloader for serial flashing via USART peripheral. Here is the simple C code to enter into the bootloader for STM32L0xx family MCU.void Jump...

WDGA bit not immediately set after WWDG_Enable().

STM32F405 using STLIBF4 v1.4.0Near the beginning of my code, I enable the windowed watchdog withWWDG_Enable() Shortly thereafter, I have a conditional block that executes only if the windowed watchdog is enabled, i.e.if ((WWDG->CR & WWDG_CR_WDGA) != ...

HAL_SD_WriteBlocks_DMA - not writing or succeeding

When attempting to write to an SD card with HAL_SD_WriteBlocks_DMA() I expect the data to be written and then the card status to change to HAL_SD_CARD_TRANSFER. However, that never happens.Here's a short snippet of code I am using (this is pretty muc...

ADC using DMA i am modelling the issue i am facing is i am unable to digitize as input signal frequency is increasing can anyone help me out?

Recommended MCUs for Low Quality Cameras

Hello,I would like to use a microcontroller which keeps around 600x800 pixel one image comes from a camera and compresses it. They are very simple functions. It needs at least 600 kB RAM to keep one image. However I could not find a low-cost microcon...
