Hi everyone,I have to port one proyect from a STM32F4 to a STM32H743. In this project it is important to use the SPI through DMA, so after reading a bit about the DMA-Cache issue in this microcontroller i decided to disable the D-Cache in order to ma...
Hello,I'm using STM32H753-Eval2 board wherein MT28EW128ABA1LPC-0SIT NOR flash is connected over parallel interface(FMC mode). I want to keep some part of application code into this parallel flash, I've referred one application note from Keil which wo...
Dear all,I am working on a project with an L081KZ and want to count pulses with a frequency higher than the clock. In the post here (community.st.com/s/question/0D53W00001EyzG5SAJ/) I thankfully got the tip to use the LPTIM as it has an asynchronous ...
Hello I am trying to learn I2C communication between 2 STM32F103C8 MCUs. MCU1 acts as the master and MCU2 acts as the slave. I am using CubeMX to configure the settings however I could not establish a link between the 2 MCUs. What I wanted to happe...
Despite its up-trending equity and healthy appearances very few we've spoke too as of late are getting accurate forecasting relevant to STM manufacturing and parts' stocks. This makes business planning difficult at our end and production impossible w...
Hi,I'm trying to write a code that can receive a new app via uart. Can erase the unused bank. Writes the new code in that bank, flips the bank boot bit and then performs a reset. I also made a small app on a PC that reads the .hex file generated by m...
Please, I need an example of how to connect P-L496G-CELL01 to AWS IOT
I am trying to migrate the keil project into stm32cube ide. startup file is generating errors. if I add the object files of keil project main.o, stm32f1xx_hal_msp.c and stm32f1xx_it.c along with the startup file(startup_stmf105rbtx.s generated from S...
My SD card interface (using SDMMC1) stops working after the SD card has been removed/re-inserted.I have tried un-mounting using f_mount(0, &SDPath, 0) and then re-mounting with no success.As a test, I executed the following for each transaction:f_mou...
