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 ...
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.
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...
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...
Posted on December 01, 2016 at 16:37 Hi , I'm using STM32L486RG microcontroller and I'm trying to use the SDMMC IP to interface with EMMC32G-M525-X01U an eMMC memory from Micron with 32Gb of size. I found in the reference manual that the SDMMC ...
Posted on December 19, 2016 at 19:45Greetings,I need to come up to speed quickly on the STM32F4 series processors. I have been in embedded development for a number of years and have experience with Renesas, PowerPC, and PIC32 processors, etc and now...
Posted on February 13, 2015 at 09:55Hi all,I´m trying to implement a Independent Watchdog functionality on my STM32L0.In HAL description pdf I´ve read the following sentence that give me some doubts on me:STM32L0xx devices provide the capability to ...
Posted on December 14, 2016 at 20:46I'm using an STM32F401 and am trying to understand the power consumption when the device is powered (3.3VDC) and held in System Reset. Can you tell me what the expected current draw will be when this device is he...
