I'm getting a lot of noise from my STM32 design, which is just supposed to be direct line-in/out I2S with DMA.I'm feeding in a 440Hz sine wave to my CS5343 A/D converter:And this is the output I'm seeing from my CS4344 D/A converter:If I zoom out a b...
Hi, i have some rather strange problems with my custom with an STM32F103C8 mcu on it. It is programmed via an Nucleo ST Link v2/1 and it works fine most of the time. I can load some test sketches on it via Platform IO or STM32CubeIde. But after a fe...
Hi, anyone know there is a register that can count the pulse directly on STM32H7?I know there is a timer in capture mode, it can generate interrupt when detected edge high or low. But this counter does count the period time only, does not count how m...
Iam working in STM32F723ZE controller I have downloaded flash loader demonstrator, but it does not have map file stm32f723ze controller.Does any one have the correct map file for this device, Can you please share this.I have created one but doesn't w...
Hi,I wanna use Unity test framework so i cloned from github Unity files. And added my STM32CubeIDE project. And write a simple code for test but i failed when i try build project. Is there anyone know how can i implement unity and use this framework?...
Im trying to write to and read data from 10 eeproms in parallel. I first transmit the data in parallel to all the eeproms via spi, I then read data in parallel by first transmitting the address of data stored in the eeprom and then transmitting dummy...
I know its clock is provided from the APB1, but I can't figure out how to calculate and what are the relations between fdcan_ker_ck and fdcan_pclk
Hi to all!I have an Nucleo-F767ZI board and I noticed a problem, in the I2C1 periperical.I have redirect the I2C1 pins on PB8 and PB9 for comodity and left PA6 and PA7 free and the I2C1 work well.After a couple of days, i have used the PA6 pin as out...
Hi,I would like to have more informations about the both integrated comparators in the stm32l052 because we only have the propagation delay informations in the stm32l052 datasheet.I would like to know the rise/fall time and propagation delay vs. over...
I have noticed some very strange behavior with the I2C controller. It appears that when it has a slave address match, it sets the ADDR ISR flag and raises an interrupt ( if enabled ). If I have a breakpoint in the interrupt handler, the ISR BUSY fl...
