Posted on June 18, 2014 at 08:49 Dear Community! I'm using DMA to transfer the ADC1 results (100 consecutive data) to some incremented memory address. DMA is in Normal mode (not circular), it is transfering 100 data, repeatedly over time....
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 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 July 22, 2014 at 10:53 Hello, I have a problem with the initialization of the SPI1 from my STM32F It doesn't work and I don't now what I doing wrong or what I forged. When I write something in the data Register ( SPI1->DR), nothing h...
Posted on August 02, 2014 at 08:21Hi,In the HAL documentation, stm32fxx_hal_uart.c & .h, I can read that in interrupt mode, the HAL_UART_TxHalfCpltCallback is called after half of tx is transfered but this is wrong.The HAL_UART_TxHalfCpltCallback is...
Posted on August 05, 2014 at 07:53Hi All, I am having an issue with I2C on the STM32F4. After successfully transmitting an address byte with values below 0xF0 , but when address value is more or equal 0xF0 (e.g. 0xF0, 0xF2, 0xF4 ..) - the slave ack...
