Posted on July 16, 2014 at 10:45I'm trying to understand how to build a buffered serial handler using DMA. I currently have an interrupt driven handler, that adds characters received to a circular buffer, but due to the lack of a FIFO on the USARTs,...
Posted on July 23, 2014 at 11:42Dear all,I have several questions regarding ADCs in STM32 (more specifically, I use STM32F407ZG). Let me explain you how I use them:1) I have 3 ADCs that are triggered by the same timer (TIM4), and that are used in sc...
Posted on August 06, 2014 at 11:53Hi, I want to program the STM32F429 with the flash loader demo, but there is no .stmap file for it! Is there an official file or has someone created it yet? Any help appreciated. Thanks, Chris.
Posted on August 06, 2014 at 09:15Hi, I am trying to reset the Time and Date (TR/DR) registers in STM32F2xx using a logic as below: reset_func() { // Disable write protection // Enter init mode RTC->TR = 0; // Reset TR // Exit init mode // Wait f...
Posted on August 05, 2014 at 10:31 Hello , I have successfully implemented a quick and dirty communication between the STM32F407 and an external ADC ADS1278 via the SPI, using DMA. Everything seems to work fine until the moment I try to ...

Posted on August 05, 2014 at 19:36Hello,I'm new to the concept of using DMA with ADC on STM32F072 MCU and I want to read 6 ADC channels (PA0 thru PA5) using DMA.Initially I tried reading the 6 channels just by configuring the ADC as follows:void Adc...
Posted on August 05, 2014 at 14:58Using an STM32F103, I want to wake from Stop mode by RTC alarm after 5 seconds.I have set EXTI on UART_RX and #17 for RTC.Here is what I know: I can put the MCU into Stop mode (via WFI).I can wake from Stop via UA...
Posted on August 05, 2014 at 15:12HiI'm trying to interface an OV7670 module using STM32F401 discovery board. First step is to get this SCCB interface going, which seems to be an I2C ripoff, http://www.ovt.com/download_document.php?type=document&DID...
Posted on August 05, 2014 at 15:04 hello, I try to communicate with an eeprom and I was able to initialise I2C1, the eeprom acknoledges when I send the adress command and I am able to send data to the I2C but the data are not allways the same, s...
