Posted on January 15, 2016 at 08:33I have been using ST-Link to flash the firmware of STM32L151Cx. Now, I would like to add the feature of flashing the uC using USB. I have checked on the datasheet and knowing that if I set BOOT0 = 1 and BOOT1 = 0 a...
Posted on January 19, 2016 at 08:06I am trying to generate the PWM from STM32F4 micrcontroller. The PWM output was done but it is 0-3.3V range. May I possible to configure the PWM voltage range (0-5V) if so, can someone guide me the way to proceed i...
Posted on January 20, 2016 at 10:38 Hi, i try to create a movie by using a file which is not available in addressable RAM or ROM. The file is stored on USB. I use this funktion: int MS_GetData(void * p, const U8 ** ppData, unsigned NumBytesReq, U32...
Posted on January 13, 2016 at 18:53 So, I'm trying to take the plunge into HAL with my STM32F407VG to be more ''future-proof'' but HAL seems to fight me at every avenue. Today's headache: I2C. Something that is usually pretty trivial to do has t...
Posted on January 04, 2013 at 21:21I need to sample 2 ADC channels at a rate of 200KHz I also need to sample another ADC channel at a rate of kHz.Currently I use the same ADC (ADC3) for all 3 channels.During the initialization, I supply the DMA with...
Posted on January 15, 2016 at 09:16Hello! I am using a STM32F302 custom made board. When I set TIM2, CAN_TX and CAN_RX at the same priority, CAN_TX and CAN_RX interfere with the performance and interrupt timer of TIM2. I checked the user manual and ...
Posted on January 19, 2016 at 23:54On stm32f072xb (Discovery board), I am able to detect an interrupt on PA0.Using the example provided, I configured the external interrupt as such. EXTI->IMR = 0x0001; /* (3) */ EXTI->RTSR = 0x0001; /* (4) */ ...
Posted on January 10, 2016 at 02:08 Hi everyone, I am trying to connect a nucleo board to an ESP8266-01WiFi board using UART1, I've used the STM32Cube to generate the project. I've added the NVIC and there is aUSART1_IRQHandler function g...
Posted on January 18, 2016 at 20:10 Hello, I'd like to create a sequencer on my STM32F100RB (@8MHz) to control 8 independants PWM channels. I configured a timer to generate a 10us interrupt wich call the update function. //timer 10µs...
Posted on January 12, 2016 at 16:22Hello. According to UM1907 I can power the board via ST-LINK USB connector (CN14) if the host PC can deliver 500mA. My board doesn't start using CN14 connector. When I power it from the same USB via usb_fs (CN13) o...
