Hi, the device have some kind of limitation on the usage of DMA?What I did:1 - Implemented DMA0 stream 0 and 1 to do the following:DMA0 stream 0 - Update the TMR2 ARR when TMR2overflow. Generate an Event on DMA transfer.DMA0 stream 1 - Sync with the ...

Hi, I did a code to select which channel I want to enable in operation according to some parameters when I start the ADC configuration and TMR.I have the ADC2 with ch5 and ch10, this work fine, both channels, or only 1 of them.On ADC1 I have ch2 and ...

Hi, I have a buffer with 65000 values in 16 bits from the ADC read that I need to provide to my computer running a python code.Any suggestion how can I handle this in both sides?I'm trying to use this function but I'm getting weird data when I'm list...

Hi, I'm using a Nucleo-H723 board and I need to sample 4 ADC's with variable sampling rate, maximum 1Mbps.I configure the TMR2 with the time stamp (10ms, 1ms, 10ms, etc...), and TMR3 with the sampling rate that is the input for the ADC trigger.Values...

Hi, I'm optimizing the decoupling capacitors of the board using PDN analysis with ansys siwave tool.And I need to set the requirement for the IC.Do you have a recommendation for that?For example, the IC needs: 0.1ohms between 0 and 10MHz, then 0.2ohm...

My mistake, I change the jumper from SB60 to SB65 and now it's fine.My jumper configuration of the board was not correct to my usage.

This is the NUCLEO-H723ZG.

Yes, this is the PC code.STM32 was fine.Im having other troubles now with the ADC but it's not related with this.https://community.st.com/t5/stm32-mcus-boards-and-hardware/ch2-on-adc1-does-not-work-while-ch15-or-ch2-ch15-works-fine/td-p/733584

I will try to configure my ADC in dual mode to see if it fix the problem:ADC1 and ADC2 are not impacted when running in dual mode, as they operate sampling and conversion at the same time. And it would not explain why when I select only the CH15 or b...

With this code I was able to read the correct values.Thank you for the support. def read_serial_data(buffer_size, output_file): # Buffer to store the received binary data buffer = bytearray() while len(buffer) < buffer_size: # ...
