I'm laying out a board using a STM32F103CB and I'm connecting to an I2C peripheral, and I noticed that on the STM32 there's a third I2C pin, labelled SMBAI - what is this pin, I'm unfamiliar. Is this an address pin for the STM32 for slave option? I c...
Hai,i tried configuring UART1 on PA9 and PB6 designed to communicate with two different devices.I tried transmitting data by configuring each pins individually and disabling (configuring the pin as low) the pins after transmission.My Transmission doe...
Hello!I have just currently developed a matrix library for embedded systems. It works for all systems. The problem is that using matrices, takes lot of both ram memory and flash memory. So i need a better controller, but the largest RAM from STM32 i ...
Dear Sir:We are working with a STM32F429VIT6 and we would like to debug our board with JTAG boundary-scan IEEE 1149.1.WE need to know if we can read and modified the pin status as the IEEE 1149.1 says. If you JTAG is 100% IEEE 1149.1 or it has some l...
Posted on July 20, 2014 at 15:58Hi all,Where can I find more documentation on the STMTouch library? I have read UM1606 but don't get how it works.The manual says to start with one of the included example files but I cannot get them to work on the Di...
I have uint16_t array[2000];HAL_ADC_Start_DMA(&hadc1, (uint32_t*)array, 2000);I get values from 0 up to 65535but when I declareuint8_t array[2000];I get values 0-255I shouldn't be bigger than 4095 since it is 12 bit resolution for ADCI have STM32L416...
Posted on June 20, 2018 at 15:33Hi All,I'm developing an application using CubeMx to generate the basic code. On CuebMx I enabled freeRTOS and LWIP.Now I would like debug my threads but Eclipse gives me access only on the thread in esecution before ...
The SDRAM HAL module has DMA functions but there is no tab in CubeMX to set up a mem2mem DMA channel. This is with CubemX 4.27.0. Is the DMA a pre-requisite for LTDC operation or does it use it's own internal memory access.
Posted on August 11, 2017 at 05:02Hello, I am using an Olimex-E407 board to measure some signals (AC signals). After some reading on ADCs I learned that there are a few error that have to be taken into consideration when doing measurements and some ...
Hi,I've been playing around and refactoring a small test app for the STM32F769 DISCO board. The app runs fine and I retest after even the smallest code tweak.What I'm seeing is that physical position of the function SysTick_Handler within the source ...
