Posted on November 08, 2017 at 10:04Hey, I'm using STM32L496G-Discovery before our PCBA will arrive. According to the docs there is 8Mbit (1MB) PSRAM on board, but in ALL ST examples with the board just 64k of it defined into icf (from 0x1000000 to ...
Posted on May 21, 2017 at 22:05hey guys,i'm interested in a SD breakout board for my STM32F427 disco board.I'd like to use the MCUs SDIO Pins for the communication with the SD breakout board.Of course when you search for 'sd breakoutboard' there are...
Posted on November 08, 2017 at 13:41I selected the 32F769IDISCOVERY board in CubeMX.Why is UART7 in CubeMX disabled?The pins in the conflicts list are not mapped or active.For my app I need the Arduino Pin D3 which is UART7_RX.I studied the schemati...
Posted on April 25, 2016 at 10:36This is one for the ST insiders. On a Nucleo64 (SB21, SB29, SB44 all disconnected) with STM32F446, the PA5 pin has been configured as AF5 (SPI1_SCK/I2S1_CK), push-pull, OSPEEDR set to 0b11 (and later tried also 0b10)...
Posted on September 20, 2016 at 13:08 Hi, I use STM32F410RB, and I need to trigger an ADC1 scan regular conversion every TIM1 CC1 event. I am sure that TIM1 works, because I have an interrupt that is triggered every CC1 event. I tried to ...
Posted on October 06, 2017 at 17:58While compiling a project with syscalls.c generated by cube mx, there is a block like this: #ifdef _SYS_TIME_H_ struct timezone { int tz_minuteswest; /* minutes west of Greenwich */ int tz_dsttime; /* type ...
Posted on November 07, 2017 at 23:41 Hello, I am trying to run a custom example of USART6 transmitter from the STM32F4 Discovery (so using an STM32F407VGT) and I am having problems since I only see garbage characters like '�' through the PC se...
Posted on November 08, 2017 at 14:28Hello Everyone,I have a question about STM32F303VCT6 MCU's Hardware Comparator Unit.I want to use 6 of the comparators as window comparator. I have no problem with this installation. But I also want to use this 3 ...
Posted on October 27, 2017 at 20:06Hello ! I am working on STM32F207 controller , where I am trying to transmit my data over UART2 at TXE Interrupt . i have used ISR mention in attached file but its not working , problem is it stuck in Interrupt lo...
