Why is my frequency being effectively doubled?
I'll try to explain everything with detail as this is one will be a hard one to explain.Essentially what I am trying to achieve is sum both the left & right channel to produce a mono signal to be outputted via I2S as the subwoofer line.The problem I ...
Resolved! I no longer can't get I2S working on a STM32H7 anymore. Need help.
Hi guys, I have no idea whats going on. I no longer can't get the I2S peripheral working on the STM32H753ZI.The I2S was working. From the last post the Tx was not working, but as I kept working on the code to get the Tx back online, now the clocks th...
Resolved! What does "CHLEN" and "DATLEN" actually mean in the context of I2S
Hi guys I am having troubles in understanding the "CHLEN" & "DATLEN" from PG. 2251 from the STM32H753ZI The reason I am asking because I am doing DSP, and I noticed when I change DATLEN from 16BIT -> 24BIT my DSP works perfectly, but when its on the ...
How can we avoid the adc floating values(when we leave the pin(floating)
Hai,I am working on the stm32f070c6 , I was configure the adc but it shows some floating values(when I leave the pin as floating) ) and it shows adc values approximately half of the reference voltage around 1.5V to 1.7V(here my reference voltage 3.3...
Does the DMAMUX solve the External DMA Trigger deficiency on STM32 devices?
I just came across this application note here: Click Here as this still of great interest to me. I just don't know what ST would have to lose if they have added a couple of signals for the DMAC on their future STM32 devices so it can be triggered fro...
Resolved! ping-pong ADC + DMA
Hi,I've configured ADC + DMA to get a single 12-bit sample (of 7 channels) from an ISR routine. However I'd like to implement a double-buffer 'ping-ping' mechanism in order to process the chunk [7][1024] data at the end of acquisition. This is at sam...
TIM1_BKIN noise immunity problem
Hello,I am using STM32VLDISCOVERY board. We have configured TIM1 in PWM mode with break feature enabled. But the BKIN input seems really sensitive and catches noise from the system resulting in a trip. Is there any data that says how much voltage on ...
STM32G484 CANFD transmit issues with specific frame
Hey everyone here is my situation:I'm facing some issues during a transmission of a specific Can-FD message. I'am using a STM32G484 in combination with a TCAN332D Can phy on a self developed hardware. I used Cube MX to generate code for CAN-FD commun...
Resolved! FPU and DSP in STM32
Does STM32H7B0VBT6 support DSP and FPU ?
