STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello, I am working on a project where I implemented various peripherals including a SAI configured in DMA mode. I have defined a 1024 samples buffer and used the Half and Full callbacks to fill it. Everything worked perfectly. However, I quickly rea...
I got an STM32F401CC6 blackpill module.I tried to upload via Arduino IDE the demo project blink.After succefull upload the board does not work.It lights only the red led and not the blue one.Is there any way to recover it?Thank you ,Yannis
Hi,when i use sleep mode, i have a reset problem on STM32L431CCT6 only on recent batches.I implemented the workaround described in section 2.2.5 of dm00218224-stm32l431xx-device-errata-stmicroelectronics.pdf but without success.The problem only affec...
I have an STM32F103 configured in slave mode using NSS for slave select and using DMA. I'm using 8 bit mode. When the master starts clocking the STM32F103 it always shifts out the first byte in the buffer twice. So rather than seeing 0xF0, 0xF1, 0xF2...
We discovered spurious Errors (every half a year) on reading out the GPIO Pin PC14 on a STM32F427ZIT6.The Pinis not connected on the PCB itself.Is configured as Input with PullUpAnd reads in perfectly the High state from the PullUp in 99.99% of the c...
Im working on stm32l4 series ,using external eeprom , eeprom writes four variables in 4 EEPROM addresses succesfully,but while reading EEPROM it only reads last (4th) variable on all 4 EEPROM address,Im try all methods adjusting delay ,EEPROM addre...
Hello,I have a strange problem on an STM32G071. I get ADC values every 25 ms from ADC1 channel 0 to 3 without DMA as speed is no issue. Strangely when one of the canels reaches about 1.2 V the CPU sometimes goes in a hard fault lock. There is a poten...
Where generally do I find the difference described between different mcu models in the same series with same major features. For example the difference between STM32L433RCT6P and STM32L433RCT6?
Hi all.I have a motor connected to my STM32F7 board and I'm trying to generate an interrupt for every rotation. Each rotation is 2122 ticks but I keep getting an interrupt for every pulse generated from the motor encoders. My init code is:static voi...
Hi,I started now programming the STM32F767ZI MCU and do not have any experience with 32bit uController.I have to programm a project, which includes a SPI communication to an external ADC. It must be programmed with the LL library and I'd like to do t...
