Posted on July 15, 2015 at 15:25Hi all, I am using a STM32F103VEH MCU which controls an external PN512 (NXP semiconductors) NFC RF reader. The MCU and PN512 communicate over a 8-bit bidirectional parallel interface as databus to exchange information...
Posted on July 15, 2015 at 09:22I have recently got my hands on an STM32F4Disovery board for one of my project requirements. I am supposed to use it with a transceiver and be able to transmit packet. Although I have done a bit of programming, it is ...
Posted on July 10, 2015 at 20:59Hello ST developers,I still don't know why I switched to HAL drivers (probably because there is no STD drivers for F7 lines) but I read MANY, MANY bugs in HAL library for F4 and after starting developing generic libra...
Posted on July 15, 2015 at 14:02I have a STM32L151UC, I am compiling a project getting a Hex and and Elf file, I flash the Hex file using ST-Link Utility and St-Link/V2 and I can start it on debug mode over openocd and gdb, being able to print with ...
Posted on July 15, 2015 at 16:12Hi I have adapted the program found below from the example 7PWM_Output in the StdPeriph library examples. My aim is to create 3 PWM channels each with it's respective complimentary output as well as inserted dead time...
Posted on July 15, 2015 at 00:09 I configure my DMA, and am trying to trigger it to move data from an array to a GPIO-> BSRR each time TIM2 update interrupt triggers. I have assigned a push button to enable the peripherals as per below. However,...
Posted on July 15, 2015 at 14:26Hi I have a stm32f429 board which i bought recently. When I try to flash the board the code gets downloaded, but after that when I try to flash again I get this error ''Internal command error'' ''Error: Flash downl...
