I am trying to find the datasheet, reference manual for STM32 Nucleo 144 - F429ZI board.Basically, the document which talks about Functional block diagram - how the GPIO pins are connected to which bus. Next, I am looking out for the reference manual...
Hello All,I recent implemented a DMA transfer for SD card data to RAM (technically an external SDRAM) on the STM32F765VI. Previously we had been using an IT transfer. In other words, we are now using SDCard_WriteBlocks_DMA rather than SDCard_WriteBlo...
why is it equivalent to the use of global variables, the address will not change.
Hi All,I have a project that currently has a blinky, 2 ADC channel on DMA circular which were successfully working .I have now implemented the USART2 on IRQ on my STM32F302 Nucleo. The USART2 is running at 32Mhz and 9600 baud. I have set up the USARt...
Hi community,I am trying to get timer3 to trigger on a rising edge, run for one 10ms pulse and then stop until it is next triggered. Application is AC phase control for a simple SCR circuit with 2 optos. I nearly have it working, but essentially, it ...
I had a board that I was debugging, and all was going swimmingly. Then I started getting an 'unable to connect' message while debugging. I didn't touch the hardware, nothing had changed. So I thought.To make a long story short, I had enabled the f...
Hi, I want to send a sequence of data on a 16 GPIO bus with a linked-node MDMA setup. How do I set the transfer frequency? I have set up LPTIM1 to have the required clock, but I can't find a way to force the MDMA to have this clock control the output...
All,I am getting an issue when attempting to write to the SD card using a DMA burst transfer. I am transferring bytes to words in burst sizes of 16 beats to 4 beats respectively. I am using the full FIFO and direct mode is disabled. Memory is increm...
Hello,I am having issues with using the DMA to transfer SD card data to RAM. This may have to do with my configuration settings, because the FIFO error register is automatically set when I configure the SD card DPSM (not when I enable the DMA configu...
Hi all, I’m run a project that use printf with: Eclipse IDE for C/C++ Developers Version: Neon.3 Release (4.6.3) Build id: 20170314-1500If I add -u _printf_float to linker flags I’ve error from compiler:Invoking: MCU GCC Linker arm-none-eabi-gcc -mcp...
