Bug in BSP_LCD_ReadPixel
Posted on July 22, 2016 at 15:44 Hi, Using CubeF7 with STM32F746G Discovery board. Found a weird bug in STM32Cube_FW_F7_V1.4.0\Drivers\BSP\STM32746G-Discovery\stm32746g_discovery_lcd.c : uint32_t BSP_LCD_Re...
STM32F7 ''clause 45'' MDIO?
Posted on December 20, 2016 at 21:12How do I configure the ETH IP to send a 'Clause 45' compliant message to the PHY? We are using one that uses an OP code of '00' to access an extended register set. The processor is STM32F745IET6. I am programming ...
N-Pulse Generation Problem
Posted on December 10, 2016 at 15:43Hello,I'm trying to get exact 2048 pulses with TIM4 on Channel 1 at PB6 with a frequency of around 3 MHz after an TRGO from TIM3. Sounds actually quite simple but I've tried already the following which dosn't lead...

Posted on October 02, 2011 at 15:31Hi,I want to use PA13 (multiplexed with JTMS) as GPIO pin of stm32f103. So i configured AFIO_MAPR reg (SWJ_CFG[2:0] - 100 --> JTAG-DP Disabled and SW-DP Disabled) .Now i am unable to program or erase flash. Please ...
Send data 16bit over SPI using DMA
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...
