Hi everyone, Trying to create an eeprom API based on the AT24CM01 ASIC chip. I got the Byte write working no problem, however the IC is capable of doing sequential writes up to 256 bytes. The way I am doing this is setting the 'RELOAD' value within t...

Hey guys,Kinda pulling my hair out as to why the pull up resistor is not kicking in? I am expecting when the MCU boots up to see a nice high signal on PA4, but nothing. I am not sure what I am doing wrong. if I write a 0x01 into ODR it then pulls up,...

Hi everyone,I am trying to get the SAI1 periperhal configured in I2S Standard mode going on the STM32H753ZI. During my testing sessions I found that my master clock is so far off it doesnt make sense. Based on the figure 652 within the TRM, it shows ...

Hi everyone,I am having a hard time trying to get the max clock frequency out of the STM32H753ZIT6U.This is the revision V model and is capable of hitting 480MHz unlike its Y revision. This is my code to get to 480MHz:LL_PWR_ConfigSupply(LL_PWR_LDO_S...

Hi everyone,A new issue has occur and have no idea as to why the transmission would be sometimes corrupt. I try sending the word "Hello World" as a test, however sometimes I would receieve the word but sometimes I would receivbe garage values that va...

Edit: Nevermind, I see where I made my mistake. Its actually zero on that node due to the NMOS, I believe this is where I went wrong.

No problem, it could easily be a misunderstanding, The reasoning behind my thinking is simply within the reference manuel pg 537 Figure 73. It states "Push-pull mode: a “0” in the output register activates the N-MOS whereas a “1” in the output regist...

I to find it very bizzare as well. The periperhal is not enable when doing the configuration and clock selection (Double checked in code). Enabled only after everything is set.I use HAL just for the initiation as theres no LL variant of it, however t...

The problem has not been solve. The register settings is listed in the original question. The periperhal clock is using PLL2_P_CLK. The output clocks are just shown in accurate, as shown in the original question, MCLK is completly wrong and the FS cl...

Sorry about the confusion,The clock I am using for the SAI kernel is PLL2_P_CLK. Its set at 98.304MHz and its working correctly.What I was trying to say was I have tried another sampling frequency of 48kHz, and 192kHz and they all output the correct ...
