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...

unable to program or erase the flash
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...
