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...
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...
Posted on July 17, 2013 at 16:46 Hi all, I'm trying to get a simple ADC working on the stm32f4 discoveryboard. At the moment I simply want to obtain an input value(ConvertedValue) as a variable rather than saving to memory inDMA. I'm struggl...
