Hi I'm using STM32F7 series microcontroller. Is it possible to send 9 bit data using SPI? the reason is i have to send 8 bit data along with command bit (ie 9th bit). I have seen some option in datasheet like we can chose the data length between 4...
Hello,I want to realize a startup-counter in a STM32L0xxx MCU.This means a counter which counts how often the MCU is doing a power fail and restart for the whole life.I want to save the actual counter-value in the flash memory.But I don't want to kil...
If switching GPIOA mode from 'General purpose output' (set to 1) to Alternate function USART Tx:Will level of pin break down for a short time or will it stay rock solid at "1" ?Rem. One has to change MODERy from 01 to 10. One may go via 01 -> 00 -> 1...
Posted on March 04, 2015 at 11:20Hi The latest version of CubeMx in Ubuntu generates (export TrueSTUDIO) file Linker (xxxx_FLASH.ld) empty. I have tested this on STM32L0 and STM32F4. In Windows it all works. Has anyone encountered this problem? B...
Hello, all!I need to explore an option to connect a DRAM to an MCU, and still ahve at least 40 PIOs and 16 AIOs left. and would like your input:Is there a comprehensive tutorial on how to connect and use a DRAM with an STM32?Any specific keywords I s...
Hello,Due to so attractive price + some specific features, the H7 Value Line looks to me very attractive to take into a new design, but 128kB Flash is not enough for me, I have to take an external flash, which is QSPI. I have a few basic questions a...
Hi! Wanted to know if i can use BOOT0 as GPIO input after my stm32f7 SW is up and running?
Hi,I am using PB0 and PB1 (no choice) alternatively but synchronized as PWM output and input/compare.For output, the only way to have two different DMA channels is to use a complementary output for one the two I/O.It seems a timer complementary outpu...
I am using the STM32F103C8 (blue Pill) and have been having lots of troubles with reading multiple channels on ADC1. Here is my init code using firmware 1.7: ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC1_Init 1 */ /* USER COD...
I'm currently using an STM32F4 board for a project that requires fast ADC conversion (2.4msps per channel, all 3 channels simultaneously) *and* pretty extensive cross correlation. Due to the clock tree of the F4, if I want to use the highest ADC cloc...
