I am trying USART communication with using DMA. Code written with HAL library is working on STM32F0 but it doesn't work on L0. I am getting irrelevant data at terminal.Also HAL_UARTEx_RxEventCallback function can called on F0 but not on L0.Here is t...
HiI am using stm32l496 in lprun mode but the current consumption is equal to 1.2 mA while in run mode the current consumption is equal to 3 mA while in the datasheet, the current consumption in the lprun mode is about 220 uA.how can I reduce the curr...
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...
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...
I'm new to embedded design, and I'm trying to wrap my head around the pinouts of the STM32L051K8T6. It says on the webpage it has two SPI buses, however the datasheet it seems to list one (SPI1) in two separate places (pins 11,12,13 & pins 21, 22, 26...
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...
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) != ...
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...
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...
