Posted on May 04, 2015 at 02:31I found a bug in stm32f4xx_hal_nand.c module, in ''HAL_NAND_Read_Page'' function!Need to change this line: *(__IO uint8_t *)((uint32_t)(deviceAddress | ADDR_AREA)) = 0x00; to this: *(__IO uint8_t *)((uint32_t)(deviceAd...
Each touch sensor features 2 sets of electrodes: the Transmitting ones (also known as Tx, or the driving electrodes, or simply X electrodes) and the Receiving ones (also known as Rx, or the sensing electrodes or simply Y electrodes).Electrodes are us...
Hello!I have to build a system that throws data simultaneously to 6 16-bit ports. It should be bit-accurate, so I was thinking about preparing all the DMA channels with one single timer, and when everything is ready, start the timer. I already did th...
Hi everyone,I'm using STM32L4R9 to develop product which run on RTOS kernel. Previously, I used a other Cortex-M4 chip run on RTOS platform in tickless mode, a 32 bit timer counter is used for calculate RTOS tick and this timer-counter able run on lo...
Posted on December 09, 2016 at 17:12Hi,After playing with the STM32F746G Discovery for a while I decided to get a Waveshare OPEN746I-C kit with a 7 inch LCD with capacitive touchscreen as I wanted a bigger screen and access to more of the pins.I've ...
Posted on March 02, 2015 at 01:34Hello,I would like to give external oscillators (TCXO, VCXO, etc) a try as HSE but can't find any diagram or documentation about it regarding STM32(F427). Could you please help with these three questions : OSC_IN ...
In auto baud rate situation is there a way to know the actual baud rate of the uart, anthe the other parameters linke size and parity?huart1->Init.BaudRateseems to have the initial parameters but not the actuals.
Hi, I am running an STM32L4 on a custom board with a 64mb PSRAM attached to it. I can write to any address on the PSRAM however I want to store a large array of sample data on the PSRAM itself. Basically, I want to do something like this int a[4] = {...
It's my first time to use STM23L031F6P6，and i got some troublesboth UART2 & LPUART1 don't work after resume from STOP modeis there somebody can help me？main code shows below：void test1(void) { HAL_Init(); RTC_Config(); ...
I have a problem on a STM32F071C board. The PLL will not reach ready state. I am using the HSI and in order to reduce current consumption I want to devide PLL from 8MHz down to 2MHz. This works fine on most board (18 out of 20) but on some the PLL_RD...
