I am trying to get an STM32L0 MCU to startup as quickly as possible. The datasheet says 5us wake up time from flash memory, but I am getting nowhere close to this. I loaded a super simple program that just toggles a GPIO and watched it on a logic ana...
I understand the general concept of why global variables are not a great idea but I have a specific use that may make sense and I'd like to see if anyone has a better approach.I time stamp a lot of events in my applications and also calculate time in...
Sorry if this has been answered elsewhere, but I'm not seeing it. For background, I do a lot of work with Nordic, and in their I2S implementation, you feed two buffers to the peripheral, then every time a buffer has been transmitted/received, it swi...
Hi,Am working on a STM32F745VG micro controller and i want to use multiple uart using dma. Majorly facing issue at the reception side.When i try to receive data from uart 1 sometimes my uart 2 also receive the same data.Even though their handler are ...
Hi everyone .I'm looking for a demo code to run the SD card (16gb) with FatFs on the STM32H757 i-EVAL Board.When I generate it with CubeMx the demonstration doesn't work (I didn't forget to activate the transiver)Thanks you =)
Hello,I working on the stm32f070c6t6 , i want to transmit an adc value to the LabVIEW VISA and storing the adc values in the labview array further processing . but when i continously giving the command from the USB COM port for adc value sometimes it...
Hello ,I am working on the stm32f070c6 controller , i am reading the adc values from controller and passing to the serial monitor of USB virtual COM port, but i want to checksum the values before transmitting the adc values to the serial monitor .how...
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...
