There is a minor issue in pin names of STM32H750XB datasheet
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
Trying to integrate the waveplayer from stm32137 example in L4+ MCU. However, the loop updating the DMA buffer only enters DMATxComplete on 3 occasions?
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...
DAC output error
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...
Resolved! What is the difference between the STM32F401RET6 and STM32F401RET6U?
Looking to use the device on a custom design using some of the resources from the Demo Kit Open Source data.
wrong data send with slave i2c1 on STM32F103RCT6
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...
EXTI line got odd/even interrupts count.
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...
On an stm32L4 When you enable input capture on timer 16 it appears to join pins PB6 and PA6
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...
Resolved! STM32H743 double precision FPU process single precision data
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...
timer 16 interupt not trigering on a stm32L432
Im migrating the code from a stm32L031 to a stm32L432 and the timer interupt isnt triggering Ive set the LED to toggle in the CaptureCallback. This code works on a L031 using timer22. Clearly Im missing something obvious;void HAL_TIM_IC_CaptureCallba...
