Posted on September 22, 2016 at 12:51Hi all; I am trying to comunicate with an external flash memory with my STM32F429. I can see my signals in the oscilloscope . I see how my microcontroler starts the clock and write to the bus but the NSS signal d...
Posted on September 22, 2016 at 13:24Hello to All, recently I coded an emulator of an old Apple-1 inside a STM32F401 Discovery board. It is capable to generate a PAL/NTSC composite video signal, it's interfaced to an old Macintosh 128K keyboard thro...
Posted on September 22, 2016 at 14:55The RAM-test procedure STL_FullRamMarchC(void) of the IEC 60335 SelfTest library ends with a HardFaultException. Debugging the function Shows that this happens after Step 6. The return address seems to be lost. ...
Posted on September 22, 2016 at 02:57Looking at AN4099 app note its not clear that the STM32L151VEY has the same capabilities/software support as the STM32F0xx in terms of setting up TIM16/17 for GPIO (PB9) for infrared txcr. Is it possible to confi...
Posted on August 29, 2016 at 11:04Hello,I have a following problem, I have a Nucleo f429zi board and after ST-link removal I am unable to run code on it. I've chcecked the solder bridges, I'm using SWO - the debbuging seems to be fine, the cpu is st...
Posted on February 14, 2016 at 21:24 Hi, i write bootloader with sdcard upgrade option. During first bootloader start (after power on, or MCU programming using stm-vldiscovery programmer) everything works well. When I restart MCU using N...
Posted on September 02, 2016 at 19:53I am unable to get any output from the COMP1 comparator on an STM32F072RB on any pin other than PA0. The datasheet ''STM32F072x8 STM32F072xB'' states on pg 41 that COMP1_OUT should be available on pins PA0 PA6 an...
Posted on September 21, 2016 at 02:43Hi dear all,I am using STM32F070RB-T6 to control a buzzer for 10 sec beeps and a power ON press key in my circuit.How to use RTC, DMA here in LSI mode?Kindly share code and disscuss it.Thanks in advance.
Posted on September 01, 2016 at 05:34Hello, We bought 10 of these boards and want to run USB host and log screen outputs through UART6 to Hyperterminal. When we run the USB host example, things work fine. When we run UART_com_IT standalone, things w...
Posted on September 21, 2016 at 17:07Hi,I'm having difficulties with STM32F4xx SDIO when using DMA transfer in circular mode (single buffer or double memory buffer alike). SDIO transfer (multi-block read or write) completes successfully, however DMA...
