The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on April 10, 2017 at 12:51Hi everyone,I've been struggling with a problem a few years ago.I want to send data to my computer via uart and to free the mcu, I need it to be done with dma.The problem was, the first transmission worked fine but I...
Posted on April 11, 2017 at 17:04HI all,I noticed in the F76/F77 Errata (DocID028806 Rev 4) that Errata 2.2.2 ('BSY bit may stay high...') should probably not be in the I2C section as it discusses a SPI problem.Thanks,Dave
Posted on April 10, 2017 at 21:07We want to use ADC2 but it is not listed as an altenate function but as an additional function in RM0090. So I was wondering how I should configure the pins.This is what I am guessing is correct:GPIO_StructInit(&GPIO...

Posted on April 10, 2017 at 11:50Hello, I'm using STM32L486 microcontroler and I have to implement eeprom 1Wire driver (DS2431). As first implementation, I used _NOP operation to generate 1�s Delay. It was working correctely and I was able to write ...
Posted on April 06, 2017 at 20:25Hi!I have a question regarding the stm32f0 DMA engine. I am using an stm32f0discovery MB1034B evaluation board.I have the following setup:The SPI dma is configured to transmit 3 bytes from memory to the spi periphera...
Posted on March 31, 2017 at 15:55Hi all.I want to know, can I use two different SLink-v2 (SWD) debugger to debug separate STM-ARM based system? I have STLink v2 debugger and discovery boards (which can be used as a debugger). I've designed a board w...
Posted on April 09, 2017 at 21:57Hi!I was wondering what is the correct way to abort an ongoing DMA transfer?I have a situation where it seems like there was an incoming DMA request while I had the DMA disabled.I disable all channel triggers and whe...
