Posted on October 08, 2015 at 16:23 I'm trying to understand DMA usage by testing a simple application. The idea is to allow USART peripheral to access read and write from and to memory directly, by using DMA technique. I'm testing this on htt...
Posted on October 09, 2015 at 13:23 I have I2C slave working to a point but have an event code which causes the isr to trigger continuously. Simplified code below. Now I am using a ''Total Phase Aardvark'' to ask for 8 bytes of data and ...
Posted on October 09, 2015 at 12:02hallo,i am trying to transmit data to stm32 from an android phone.i setup a receive and send buffer for usb each with 256 bytes.if i send one bulk packet with less or equal to 64bytes and echo in back things work f...
Posted on October 09, 2015 at 10:47Hi, I'm using a STM32 L051K8 and i'm kind of short in IO, is there any way to avoid using an ADC pin to measure VDD?? #vdd #stm32
Posted on October 08, 2015 at 13:32I must select a MCU for a project which should use a TFT LCD (240x320). I would like to know what are the main differences between FSMC, FMC and LTDC interfaces for driving an LCD. If FSMC is OK then the value line...
Posted on October 08, 2015 at 13:18Hi, in this part of the DMA-SetConfig() function the comments are wrong. /* Memory to Peripheral*/ if((hdma->Init.Direction) == DMA_MEMORY_TO_PERIPH) { /* Configure DMA Stream destination address */ hdm...
Posted on October 08, 2015 at 11:02I've a new project were I need to use NAND flash connected to STM32F2 or STM32F4. I need to support NAND Flash chips with 8, 16, 32 or 64 Gbits. These chips have page size of 4096 or 8192 bytes, and the required nu...
Posted on October 08, 2015 at 18:29Hello, I have been trying for days to get the ADC in STm32f4Discovery board to work in triple regular Injected simultaneous mode with no luck. My intended goal is setup the ADC to work in triple Injected simultan...
Posted on August 25, 2015 at 20:45I am thinking of building several ''shields'' with GSM, GPS, LCD, MicroUSB and MicroSD connectors to stack up on the STM32F401 Nucleo board (by the dual row connectors, not Arduino) but i'm worried about the signal ...
Posted on October 08, 2015 at 17:35 Hi, I'm working with stm32f4-disco. I made a code that works well: the micro waits for an external interrupt, and when receives the interrupt it makes pulses of 40kHz with a duration of 1 ms. Now, I wanted...
