Posted on February 09, 2018 at 01:13HiI am using ST-LINK to program a STM32F103RBT6. I program it and the unit runs - then I set option bytes via the menu for readout protection and the unit stops. Power cycle et al does not recover. Are there ot...
Posted on February 11, 2018 at 22:27Hi there, im trying to work on some UI for the stm32f429i with StemWin. I set up everything with this tutorial http://slemi.info/2017/07/01/stemwin-touch-screen-stm32f746g-dicovery-part-2/Everything's okey but in ...
Posted on February 11, 2018 at 12:36I'm need to generate N channel (N>1) PWM output in a such a way that one channel is main 'governor' lets say ch0. Every other channel repeats the same duty, but with time shift (or or phase shift). Ch1 need to set...
Posted on February 07, 2018 at 04:36Hi,We designed a new PCB for the STM32F205RGT6, but we�re having trouble toggling GPIOs using the chip.We wrote a simple program that toggles a GPIO every 250ms, we confirmed that the code works on the http://www....
Posted on February 11, 2018 at 19:03What is Software NSS and Hardware NSS in SPI? Which Nss mode should we select?Do we need to connect the NSS pin (between master and slave) in Software mode?I read the NSS pin management in Reference manual, but I ...
Posted on February 11, 2018 at 15:00Hello everyone. I have encountered problem with USART1 on STM32F446RE. It seems it doesn't work for me. I have used multiple times USART2 and it works as it should, but USART1 with same configurations just refuse ...
Posted on February 11, 2018 at 08:07Hi, I'm interested in better understanding how SDRAM works with the on the STM32F4 Discovery development boards. For example, I have an STM32F429-Discovery. It has 64-Mbit SDRAM on the board.I've closely examine...
Posted on February 08, 2018 at 11:43Hi,for a new project I have to transfer data from a SD card to a serial line SDI (1 GPIO line). The data has to be synchronized with a 20 Mhz clock CK. At certain times , controlled by an external encoder signal, ...
Posted on February 10, 2018 at 11:39Hi all,Just wanted to check with the collective wisdom on this forum. I'm planning to do 3-channel ADC periodic sampling at 10kHz sampling rate. After reading up on the internet resources, two ways appeared to be ...
Posted on February 10, 2018 at 20:49 Hey everyone, I've got a small issue. I've got a Dma that fills a buffer(Double buffer so 2 actually) with data at every rising clock edge. I only want this clock to trigger the DMA 192 times until a reset s...
