I had this problem on my project, so I created a new one and added only I2C to pins Pb7 and Pb6. I set I2C from disable to I2C and I set them to "pull-up" . That's about it. And the code gets stuck in the HAL_I2C_IsDeviceReady function.I have also se...
I have a design that uses and STM32L4 series MCU. The device will be hard to physically access, but has a serial connection to the 'outside' world on UART 4. The board also has a 4 Mbit flash connected to the MCU via (bit-banged) SPI.When I need to u...
Hello,I am using a Nucleo-L073RZ board for my application. Reducing power consumption is adamant. Being so, I opted to put the MCU to sleep mode with WFE in some ocasions where some kind of delay is needed, with a reduction of HCLK (64 division). I a...
Hi, is it possible to use the external RAM as a heap. I would like to do malloc and free on it. I was able to set an huge array on it by little modifying the linkerscript, but that is not really handy because than you have to do the mem managing. Hav...
When reading from the sd card is completed, HAL_SD_RxCpltCallback is executed. But when I use the HAL_Delay() function within the callback, the rest of the code within the callback after that delay doesn't run.Any information about this issue is grea...
I have an .elf file and a .mpa file both in the same directory, Debug-->project.elf and Debug-->project.map and the build analyzer is not showing any information. Any ideas on a possible solution to resolve this? SRM32 CubeIDE Version: 1.12.0
I looked at the pages for both MCUs side-by-side:https://www.st.com/en/microcontrollers-microprocessors/stm32f407ze.html/https://www.st.com/en/microcontrollers-microprocessors/stm32f407ve.htmlI can detect no difference other than the Z vs. V in the n...
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 ...
