Posted on July 14, 2014 at 15:44 Hello there, I am trying to read in serial data from UART2 Rx and retransmit out to UART3 Tx. I am using the STM32CubeMx code generator with the F4 discovery board. Both UART are configure to the same baud rate. ...
Posted on August 06, 2015 at 00:25Hi everybody, I think i tried anything i could have in mind so i decided to start a new discussion... Material : - Evaluation board with stm32l152RCT6 with st-link integrated My question is : Is anybody tried to us...
Posted on August 11, 2015 at 20:21Hi.Currently, I have configured ADC regular simultaneous dual mode for 8 AD conversions. 4 of them on ADC1 (master) and other 4 on ADC2 (slave). I transfer results via DMA as 4 32-bits words into my destination arra...
Posted on August 11, 2015 at 12:28Good afternoon to everyone!I want to develop a system around the stm32f4discovery hardware (I own this board) that acquires data from peripherals (one IMU, GPS and internal ADC) and ships it through USB to a HOST PC...
Posted on August 11, 2015 at 18:26Im having an issue erasing pages of flash. During my bootloader application while receiving a block of data I erase the page and then write the data. During testing I have the messaging protocol setup to just read t...

Posted on August 09, 2015 at 20:09 I'm sitting here pulling my hair out because I can't figure out what's going on, I've tried everything I can think of. I'm using SPI to communicate with an offboard periph, When I write to the data register the...
Posted on August 06, 2015 at 13:19 Hello, I need use a port both input and output. What should I do? Should I use something like this? GPIO_InitTypeDef GPIO_InitStructure; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE); GPIO_Ini...
Posted on July 22, 2014 at 18:28I have a boot loader and main app. I am trying to use the MPU to restrict access to parts of the boot loader Flash and to DMA registers so that the app code can't use DMA to read the boot loader Flash (as is done the...
Posted on April 30, 2014 at 17:56Hi there,I am working on STM32F429 Discovery board and trying to figure out a proper way to enable PCROP feature shipped with this board. I can use windows st-link utility application to turn flash sector into PCROP ...
