How to use two or more timers independently from each other using the stm32h7?
Hello everyone,I am still relatively new to STM32 especially the stm32H7. ( I am using the stm32h755)I have one timer with DMA that outputs a PWM signal, I am controlling an ARGB strip. For this I have Timer4 connected with Channel 1 and it does work...
Question on SAI DMA buffer
Hi Team,I am using a the SAI Peripheral from the STM32L5 family to read data from a master device. I am employing the DMA peripheral to read the data from SAI. I have a buffer of 32kb and I am using the STM board as a slave device. I am using the HAL...
STM32H725IGK6 SRAM connection control signals review
Hi ST team We are using STM32H725IGK6 in our design with SRAM Can you please review and let us know if the PINs used for SRAM are proper?Mainly control signals
Current consumption in sleep mode for STM32f401re
Hello Everyone ,I have a wrote a code to send STM32F401re to sleep with all peripherals on at 84Mhz , as per the datasheet i should be seeing a current consumption of 18-20mA, however I am seeing a consumption of 27mA. The code sends data through UA...
Resolved! How to generate an interrupt at an F1 frequency and wakeup MCU at a different F2 lower frequency with RTC
Hello guys, I am working with an STM32L071CBT6 MCU. I want to have a cycle of 10 minutes, where MCU works for 1 minute before entering to standby mode during 9 minute.Using RTC, I want to have an interrupt every 1 minute(60 s); but I don't want the ...
STM32 UART receives Null character(\0) on reset.
Project Details:The project consists of two STM32 MCUs connected over UART (without any external pull up resistors). One STM32L4 MCU (LPUART1) acts as an AT master and other STM32L0 MCU (UART 1) acts as an AT slave. AT slave is configured to wake up ...
Resolved! STM32F429 i2c master transmit always returns busy
Hi,I'm using STM32F429 to talk to TI BQ40Z50 via I2C, and I ran into an issue I have no clue.First of all, the code simply reads registers, and it works on TI BQ20Z95. The same code doesn't work on BQ40Z50. The HAL library always returns HAL_BUSY, an...
"Pain" with D-cache cleaning&invalidating on STM32F7 family
I've read often about strange problems with activated D cache on M7 core and how it can be solved here in forum.But the STM32F7xx family has implemented a fast DTCM RAM that is accessible from CPU core and DMA peripherals.This DTCM memory should have...
Resolved! What is the accuracy of the ADC watchdog [STM32F303]?
I have successfully configured the adc watchdog. But i am a bit dissapointed of the accuracy. I set the bounds to 1000 and 3000, but when i read the values of the adc from the watchdog interrupt, i get also values from within the window (up to 1025/2...
