Posted on August 11, 2015 at 09:11I need input data from GPIO with external strobe (2000 samples; strobe is about 10 Mhz). But speed of processor it not enough. Can I do it with DMA? I have found many samples, but all of them use external signal as ...
Posted on August 11, 2015 at 09:40Hello, I'm using timer3 to generate an interrupt every 10ms (it saves one value everytime to a buffer). Everything works fine until I try to save buffer data to 1 page of flash. It happens of course inside the inter...
Posted on December 04, 2014 at 16:23Hi. I'm using STM32F101RBT6 in a project, with custom PCB. I need to remap the SPI1 signals to pins PB3/4/5 (which would be SPI3, only STM32F101 doesn't have one). I also use remap to disable JTAG to free-up PB3...
Posted on August 12, 2015 at 09:35 Good morning everbody, I am currently using a STM32L053C8 and I want to generate a square waveform. My APBx timer clock is 8MHz and can't be rised. Is it possible to generate a 8 MHz squrae waveform at ...
Posted on August 06, 2015 at 09:43Hi allI have a problem. I am trying to update the PWM duty cycle using TIM1 update interrupt. In the interrupt I write values to the TIM1 CCR1, CCR2 and CCR3 registers. When I run the code nothing happens.Have I mis...
Posted on July 31, 2015 at 08:55Hi Everyone,Does STM32 DMA controller provide options to perform following copy procedureSay the data in the source memory as follows. (x, y are 16 bit each)Source Memory:x1 ,y1,x2,y2.,.,xn ,ynI want to copy to destin...
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...
