New possibilities for the ultra-low power segment!

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...

Simultaneous ADC Readings from 15 SPI slaves

Hi ;I need to know if it is possible to get 15 ADC samples from 15 ADC conversion ICs over SPI protocol with a single conversion trigger. My MCU has only 6 SPI peripherals and 3 of them have 16bits data size and the other 3 SPI have 32bits spi data s...

Writing bytes to internal flash memory blocks all interrupts on the STM32L0 despite moving the vector table and ISR functions to RAM

The ContextI have a embedded system running on an STM32L053 processor that needs to process STM32 hardware timer interrupts regularly and cannot be disabled. These top-priority interrupts cannot be prevented because it could cause a failure in the wh...

I2C dumping 255 as data instead of actual Values

I am using about 13 (PCA9554A & PCA9554AD) I/O expander IC to connect sensors to STM32 F103 micro-controller through I2C. Upto 3 PCA9554 IC works fine, but the moment I connect 4th IC, it starts to dump 255 from all the i/O Expander ICs.The data is l...

STM32F0 ADC DMA or Not DMA

Hello. I am making software with STM32F030CCT6 processor. I am trying to make ADC with or without DMA. I always face this problem in F0 series. I can read only one channel. When it switches to multi-channel, it transfers data from a single channel to...
