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...
I have a problem that the PWM timer stops working randomly, maybe once every 2 weeks on 4 prototoypes. The PWM signal is just high instead of the frequency it should do. I have added reset and recover but nothing seems to fix. Since I am not able to ...
I am using the STM32F407VET6 and SPL libraries. My goal is very straightforward, just send data over usart periodically.But when I send data (buttoncheck function) inside the timer interrupt it stucks " while(USART_GetFlagStatus(USART3, USART_FLAG_TC...
I need to write to the 4kB battery backed SRAM to hold information across power cycles, but it's not working! To be more specific:The debugger memory display shows the correct data in SRAM after a write.The data is read successfully at any time other...
HelloIm trying to implement stm32 spi multi-master function on a stm32f765 according to the below presentationI keep getting MODF error when transmitting as a master, that would indicate that the slave sets the masters NSS pin low. Even if I set the ...
HiI'm doing a project to detect collision on UART, when I get data from Rx, I will compare it with the data I transmitted, if there aren't the same, means collision occurred, then I will immediately stop my transmitting interrupt to stop sources wast...
Hi there, I'm using an STM32F103C8 and using the SPI1 interface with software CS together with DMA1 Ch2 and 3 (RX and TX, respectively) in master mode. Here is how I init my transactions:DMA_ClearFlag(DMA1_FLAG_TC3 | DMA1_FLAG_TE3 | DMA1_FLAG_HT3 | D...
I need to find one STM32 which can connect 32+ microphones ，use I2s or SAI or DFSDM， synchrony run best.
Hello,I am using STM32F765BI MCU.I want to generate an audio on both the channel of DAC using DMA simultaneously, currently I am facing a problem that I am able to generate audio only on one DAC channel at a time.So please suggest a method that how c...
Hello all , we use stm32f072.1.is this regulator LDLN025M33R can be alternative for LD39050PU33R no legssince we would like to use his "legs" .our current conception is 90mA 3.3V .thanksyaniv
