Actually I am using a single interrupt to receive, data from another processor in two different arrays. Due to this scenario and interrupt being called at two times in different arrays, only the first array receive interrupt accurately.
Hello, I'm working on a project based on STM32F446 controller. In my project, I'm reading and writing some data on the external flash. Its interface to one of the SPI port of the controller. The frequency of data accessing (reading and writing) is a ...
Hi, does library example of in-application programming (IAP) for STM32F103C8T6 exist?I would like to load software updates from MicroSD card.Also as I understand I will need 2 projects? One as bootloader to load software and another as application wh...
Hi,The example DMAMUX_RequestGen works perfectly on my STM32H755 board and now I'm trying to modify it so it uses the DMA1 instead of the BDMA. I need that because at the end I would like to trigger a SPI5 RX.Unfortunately I cannot make it work, that...
Information:- STM32F777ZI- Dual mode enabled- Application in BANK 1. Nothing in BANK 2.- For simplicity I do NOT turn on: I/D caches, ART and Prefetch, MPU.Scenario:1) Power up.2) I execute the function. CPU sometimes stalls, sometimes not, sometimes...
According to I2S example of STM32373C-EVAL SDK : "Mono audio streaming is not supported (in order to play mono audio streams, each data should be sent twice on the I2S or should be duplicated on the source buffer. Or convert the stream in stereo befo...
I need to achieve level sensitive interrupt behavior with EXTI, similar to shared PCI interrupts on other architectures.Have several OR'ed interrupt requests wired together to a EXTI input;all requests are active low.All requests can be masked or dis...
Hi all, as mentioned in the title i have an issue with the ADC configured to sampling 4 channels with different rank.I want to collect the sample in one array ( array uint16_t values[4] ) in the same order for each conversion done. The data in the ar...
Hi, I have custom HW with STM32L496RGTx. On board I have SD card slot. I tried HW with CubeMX. Setted SDMMC1 to Mode: SD 1, SD DMA - SDMMC1 and divider to 24. In code I wroted: FATFS SDFatFs; /* File system object for SD card logical drive */ char S...
Greetings to all.I'm Following some online courses to learn to program STM32. I have a very weird behavior of my board that gives me not few headaches. After reviewing, changing, testing my codes for 2 days i found a way to get my program running cor...
