Hi,I am currently implementing a guitar effects pedal using the STM32F446RE and the PCM3060 as my CODEC.I have gotten everything to work, except when I try to adjust the following parameterscf0_lim = (int)(time*l_CB0);cf1_lim = (int)(time*l_CB1);cf2_...

Hi,Am trying to correctly connect to my external NOR flash memory using my STM32F446RE's DMA.Am not sure how to go about this and the libraries I have tried are not working at all.Here's a link to the library I tried to test the connectivity between ...

Hi,I would like to know if there are any resources for learning and understanding how to communicate (read/write/erase) from an external flash memory using SPI.I am using an STM32F446RE and my external flash memory is a w25q128.Ideally I would like t...

I am currently using the HAL function ```HAL_I2S_Receive (I2S_HandleTypeDef * hi2s, uint16_t * pData, uint16_t Size, uint32_t Timeout)```in order to collect an input signal (currently being tested with a function generator 440 Hz sine wave). However,...

In terms of making the buffers volatile, yes. I had forgotten to make them volatile. Thank you. In terms of the register debugging, as far as my knowledge goes, the Hard_Fault is held in the pc register, which I suppose stands for program counter. Ho...

@TDK and @Community member using the ST-LINK Utility tool I get the follow error message when set to openOCD: Info : Target voltage: 0.001567Error: target voltage may be too low for reliable debuggingThe voltage varies but it is usually below 1 V

Thank you @Community member and @TDK I will go ahead and probe the SWD and SWCLK. I will post schematics along with the results from the probing.

Apologies, the VCAP pin has a voltage of 1.14 V and NRST is high. I however wired the BOOT0 and BOOT1 to ground, which means is booting from the user flash memory. Could this be the issue?

How can I determine that the values am reading from the CODEC actually represent the input signal?
