Posted on August 14, 2016 at 15:02Hi,I am newbie to ARM.Recently I bought a STM32F4 discovery kit and I like to start up programming it in assembly language to get clear understanding of the processor.Can anyone please provide me a small assembly pr...
Posted on July 09, 2013 at 08:50Good morning everyone,I'm currently working on a project with a ST32 and my goal is to be able to give him simple instruction in Modbus TCP/IP thanks to an Ethernet cable. Presently I've been able to code functions in...
Posted on August 11, 2016 at 17:37Hi, I'd like to designe a PCB with a STM32F7xx. You use to have in the Design/Schematic Packs also the xxx.PCBDOC. E.g. STM3210C-EVAL (MB784C, MB785A) They save lot of work and time. But I miss the PCB Document for...
Posted on June 20, 2016 at 23:21Hello Forum, I've been reading on the forums about custom bootloaders stored in flash and I was wondering if there was another possibility (possibly because I want to avoid messing with stack pointers, reset vectors e...
Posted on August 12, 2016 at 07:27STM32 external SDRAM(32bit width,FSMC interface) 16bit and 32bit writing OK,but 8bit writing is not OK, shown below,source file is also attached. Test Results uint8_t write_buf1[100];write_buf1[0] = 0x01; //0xC000...
Posted on August 14, 2016 at 19:19Hi,I would like to utilize either a 128Mb or 256Mb, and someday, maybe even a 4Gb external SDRAM chip. If they can just be swapped out on the board all the better.The F7-DISCO makes a point that due to design consi...
Posted on August 12, 2016 at 01:09 A few details: both code and data caches are enabled. 216MHz SysClk. Timer ISR schedules a task every millisecond. SCB.SHCSR=1<<18 to enable use of usage fault ISR for the fp trap handler. All ISR’s mentioned a...
Posted on August 13, 2016 at 19:25 Hi all! I'm trying to create a parallel synchronous data transmission using DMA and GPIO on a STM32F051 MCU. I've been following the AN4666 document that ST released, but is set up for STM32F4 MCUs. I also don'...
Posted on August 08, 2016 at 08:42Hi all,I've built USART2 connection with using none-flow-control via rs485 through my pc. Sending data from my pc to stm32f103 is working correctly however, i can't send any data from stm32 to my pc.Do you have any ...
Posted on July 29, 2016 at 18:58Hi,Has anyone worked with STM32-MAT release 4.3 on the ADC examples? Could anyone tell me how one can run this example and get the ADC reading via USART3 block back to simulink host PC?I am not sure if this example is...
