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'm trying to teach myself C++ on STM32. Unfortunately the books on C++ I have and most websites I found do not mention interrupt handling. The websites where it was explained (embedded.com, stackexchange.com, etc) did it in a way I simply do not (y...
Hi sir/madam,In the datasheet of STM32H750XB 57th page J1 pin name is given as PH0-OSC-OUT and in 61st page the same pin is given as PH1-OSC-OUT. which do we need to consider?Datasheet: https://www.st.com/resource/en/datasheet/stm32h750ib.pdf
Here's the essence of what I have at the moment. I wonder why it does not enter DMATxComplete, I have tried with 128 and 30 buffer sizes...//****** dac.c **********// DAC_HandleTypeDef hdac1; DMA_HandleTypeDef hdma_dac_ch1; DMA_HandleTypeDef hdma_d...
I'm using STM32F405VGT6 to output sine wave by using its dac.After every output sample,which is triggerd by timer, dac's data holding register 'DAC_DHR12R2' is not holding the data and is reset to zero.So the output wave is something like sine wave m...
Looking to use the device on a custom design using some of the resources from the Demo Kit Open Source data.
STM32F103RCT6 i2c work as slave mode，master i2c machine worked with clock speed 400KHz.When master read many bytes from slave,a wrong data will come out behind the address byte.in normal,master transmits 0xA1，then it will receive 0x11 0x22 0x33 0x44b...
Hi friends,I met a problem.I used one EXTI line to check a button push-and-release. EXTI line was set to be triggered by both falling and raising edge. I know there will be burr when I pushed the bottom. The question is , when I pushed and then relea...
Ive setup PB6 as a GPIO_Output and Timer 16 and an input capture which uses PA6. It appears that if you set PA6 as an input capture it joins PA6 and PB6 internaly on the trace Chanel 0 is attached to PA6 Channel 2 is attached to PB3 (green LED) and C...
Hi，STM32H743 Cortex M7 core with double precision FPU, it process 32bit float data(single precision) in my project, I wonder if it affects efficiency and performance of FPU, In my performance testing program, it's no different from Cortex M4 FUP.Th...
