Posted on March 30, 2017 at 13:43Hi Folks,I would like to learn programming STMicrocontrollers. I have basics of programming and done couple of projects for PIC controllers.I have set up the Atollic studio in my system. I would like start with toggl...
Posted on March 17, 2017 at 03:07Hello, I m a new guy in ST MCUI use CubeMX as start point and create a project for CAN1 and CAN2 Communication, and test a simple code belowresult is 'HAL_CAN_Transmit(&hcan1, 50); ' always return Time out error;can ...
Posted on March 30, 2017 at 17:44Hi to all,I have a problem about interrupt, expecially USART interrupt.I use USART1 to interface my boarf to computer (FT232), but often my routine crashes.Here is the code:uint16_t iocnt = 0;extern 'C' void USART1_I...
Posted on March 30, 2017 at 17:03Hi! ST32L476 Discovery Board is an mbed OS enabled board. If i have only an L476 MCU in my hardware design (no in-circuit debugger, but LQFP100 as well) so technically it is not a board, will my device still be mbed ...
Posted on March 30, 2017 at 16:10 I am trying to get some CubeMX PWM DMA code working on a Nucleo F767ZI board. I can get it to work on D10(PWM4/3) but not D9(PWM4/4). I have tried to get some Cubemx PWM code working on D9 and it doesn't work excep...
Posted on March 30, 2017 at 15:57On STM32F43xxx MPU If I try to program the embedded flash (with any value) without erasing it first, the HAL_FLASH_Program function does not return an error. Is this the expected behavior?#hal_flash_program-stm32f43
Posted on March 29, 2017 at 10:12 Ok, I've seen some strange things in my day but this has got to be the most insane thing I've come across. Need a brilliant person to try to help me explain this: The NFC CR95HF library is a work in progress b...
Posted on March 29, 2017 at 21:16Hi Ive been looking through documentation (and web sites), and testing some code on using the A/D on the STM32L0 processor. As the chip I am using uses the VDD as the reference voltage I am currently calculating th...
