Posted on November 08, 2016 at 13:46Hi,I want to transfer data 16bit over SPI using DMA, Like thatSPI_Transmit(SPIx, (uint16_t) value, (uint16_t) count);For driver ILI9341 function clear screen faster than using SPI mode 8 bit.Many thanks.
STM32F3 using 2 channels ADC with high impedance inputs causing cross-channel interference
Posted on December 19, 2016 at 02:18Hi. While I have found a solution to this problem, I still do not understand the root cause and would appreciate any insight as to why it occurs.To simplify the issue I am using the standard stm32F334 Nucleo hardw...
Resolved! What could be consuming power in stop mode after flashing an STM32L073?
Posted on December 13, 2016 at 00:28So I'm running a program on an STM32L073 that puts the device into stop mode to minimise power consumption.After flashing the device (via ST-LinkV2) it starts up and enters stop mode where it is consuming around 1...
